The involvement of these reward and habit neurocircuits helps explain the intense desire for the substance (craving) and the compulsive substance seeking that occurs when actively or previously addicted individuals are exposed to alcohol and/or drug cues in their surroundings cholesterol level chart pdf discount pravachol master card. Withdrawal/Negative Affect Stage: Extended Amygdala the withdrawal/negative affect stage of addiction follows the binge/intoxication stage percent of cholesterol in eggs purchase pravachol 10 mg with mastercard, and chart high cholesterol foods purchase pravachol 20mg overnight delivery, in turn cholesterol blood ranges order discount pravachol on-line, sets up future rounds of binge/intoxication cholesterol values normal cheap 20mg pravachol visa. During this stage low cholesterol foods and recipes buy pravachol 20 mg mastercard, a person who has been using alcohol or drugs experiences withdrawal symptoms, which include negative emotions and, sometimes, symptoms of physical illness, when they stop taking the substance. Other studies also show that when an addicted person is given a stimulant, it causes a smaller release of dopamine than when the same dose is given to a person who is not addicted. This is because natural reinforcers also depend upon the same reward system and circuits. This impairment explains why those who develop a substance use disorder often do not derive the same level of satisfaction or pleasure from once-pleasurable activities. This general loss of reward sensitivity may also account for the compulsive escalation of substance use as addicted individuals attempt to regain the pleasurable feelings the reward system once provided. The person who has had a cocaine use disorder has lower levels of the D2 dopamine receptor (depicted in red) in the striatum one month (middle) and four months (right) after stopping cocaine use compared to the non-user. The level of dopamine receptors in the brain of the cocaine user are higher at the 4-month mark (right), but have not returned to the levels observed in the non-user (left). In animal and human studies, when researchers use special chemicals called antagonists to block activation of the stress neurotransmitter systems, it has the effect of reducing substance intake in response to withdrawal and stress. For example, blocking the activation of stress receptors in the brain reduced alcohol consumption in both alcohol-dependent rats and humans with an alcohol use disorder. Recent research also suggests that neuroadaptations in the endogenous cannabinoid system within the extended amygdala contribute to increased stress reactivity and negative emotional states in addiction. As noted previously, this motivation is strengthened through negative reinforcement, because taking the substance relieves the negative feelings associated with withdrawal, at least temporarily. Of course, this process is a vicious cycle: Taking drugs or alcohol to lessen the symptoms of withdrawal that occur during a period of abstinence actually causes those symptoms to be even worse the next time a person stops taking the substance, making it even harder to maintain abstinence. Together, these phenomena provide a powerful neurochemical basis for the negative emotional state associated with withdrawal. The drive to alleviate these negative feelings negatively reinforces alcohol or drug use and drives compulsive substance taking. Preoccupation/Anticipation Stage: Prefrontal Cortex the preoccupation/anticipation stage of the addiction cycle is the stage in which a person may begin to seek substances again after a period of abstinence. In people with severe substance use disorders, that period of abstinence may be quite short (hours). In this stage, an addicted person becomes preoccupied with using substances again. Executive function is essential for a person to make appropriate choices about whether or not to use a substance and to override often strong urges to use, especially when the person experiences triggers, such as stimuli associated with that substance. People also engage the Go system when they begin behaviors that help them achieve goals. Indeed, research shows that when substance-seeking behavior is triggered by substance-associated environmental cues (incentive salience), activity in the Go circuits of the prefrontal cortex increases dramatically. This increased activity stimulates the nucleus accumbens to release glutamate, the main excitatory neurotransmitter in the brain. This release, in turn, promotes incentive salience, which creates a powerful urge to use the substance in the presence of drug-associated cues. The Go system also engages habit-response systems in the dorsal striatum, and it contributes to the impulsivity associated with substance seeking. Habitual responding can occur automatically and subconsciously, meaning a person may not even be aware that they are engaging in such behaviors. Especially relevant to its role in addiction, this system controls the dorsal striatum and the nucleus accumbens, the areas of the basal ganglia that are involved in the binge/intoxication stage of addiction. As described above, these neurotransmitters are activated during prolonged abstinence during the withdrawal/negative affect stage of addiction. Studies show that lower activity in the Stop component of the prefrontal cortex is associated with increased activity of stress circuitry involving the extended amygdala, and this increased activity drives substance-taking behavior and relapse. These executive function defcits parallel changes in the prefrontal cortex and suggest decreased activity in the Stop system and greater reactivity of the Go system in response to substance-related stimuli. Indeed, a smaller volume of the prefrontal cortex in abstinent, previously addicted individuals predicts a shorter time to relapse. In Summary: the Preoccupation/Anticipation Stage and the Prefrontal Cortex this stage of the addiction cycle is characterized by a disruption of executive function caused by a compromised prefrontal cortex. The activity of the neurotransmitter glutamate is increased, which drives substance use habits associated with craving, and disrupts how dopamine infuences the frontal cortex. Progression through this cycle involves three major regions of the brain: the basal ganglia, the extended amygdala, and the prefrontal cortex, as well as multiple neurotransmitter systems (Figure 2. The power of addictive substances to produce positive feelings and relieve negative feelings fuels the development of compulsive use of substances. The combination of increased incentive salience (binge/intoxication stage), decreased reward sensitivity and increased stress sensitivity (withdrawal/negative affect stage), and compromised executive function (preoccupation/ anticipation stage) provides an often overwhelming drive for substance seeking that can be unrelenting. Different Classes of Substances Affect the Brain and Behavior in Different Ways Although the three stages of addiction generally apply to all addictive substances, different substances affect the brain and behavior in different ways during each stage of the addiction cycle. Differences in the pharmacokinetics of various substances determine the duration of their effects on the body and partly account for the differences in their patterns of use. For example, nicotine has a short half-life, which means smokers need to smoke often to maintain the effect. What the body does Additional research is needed to understand how using more to a drug after it has been taken, including than one substance affects the brain and the development and how rapidly the drug is absorbed, broken down, and processed by the body. As use progresses, the opioid must be taken to avoid the severe negative effects that occur during withdrawal. With repeated exposure to opioids, stimuli associated with the pleasant effects of the substances. For men, drinking 5 or more standard alcoholic drinks, and for euphoria as well as the sedating, motor impairing, and anxietywomen, 4 or more standard alcoholic reducing effects of alcohol intoxication. Alcohol addiction drinks on the same occasion on at least often involves a similar pattern as opioid addiction, often 1 day in the past 30 days. As with opioids, addiction to alcohol is characterized by intense craving that is often driven by negative emotional states, positive emotional states, and stimuli that have been associated with drinking, as well as a severe emotional and physical withdrawal syndrome. Many people with severe alcohol use disorder engage in patterns of binge drinking followed by withdrawal for extended periods of time. Extreme patterns of use may evolve into an opioid-like use pattern in which alcohol must be available at all times to avoid the negative consequences of withdrawal. Stimulants Stimulants increase the amount of dopamine in the reward circuit (causing the euphoric high) either by directly stimulating the release of dopamine or by temporarily inhibiting the removal of dopamine from synapses, the gaps between neurons. These drugs also boost dopamine levels in brain regions responsible for attention and focus on tasks (which is why stimulants like methylphenidate [Ritalin ] or dextroamphetamine [Adderall ] are often prescribed for people with attention defcit hyperactivity disorder). Stimulants also cause the release of norepinephrine, a neurotransmitter that affects autonomic functions like heart rate, causing a user to feel energized. Addiction to stimulants, such as cocaine and amphetamines (including methamphetamine), typically follows a pattern that emphasizes the binge/intoxication stage. A person will take the stimulant repeatedly during a concentrated period of time lasting for hours or days (these episodes are called binges). The binge is often followed by a crash, characterized by negative emotions, fatigue, and inactivity. Marijuana (Cannabis) Like other drugs, marijuana (also called cannabis) leads to increased dopamine in the basal ganglia, producing the pleasurable high. Effects can be different from user to user, but often include distortions in motor coordination and time perception. Over time, individuals begin to use the substance throughout the day and show chronic intoxication during waking hours. Withdrawal is characterized by negative emotions, irritability, and sleep disturbances. To a lesser extent, they also activate the serotonin neurotransmitter system, which can affect perception. Fentanyl is a synthetic opioid medication that is used for severe pain management and is considerably more potent than heroin. Prescription fentanyl, as well as illicitly manufactured fentanyl and related synthetic opioids, are often mixed with heroin but are also increasingly used alone or sold on the street as counterfeit pills made to look like prescription opioids or sedatives. Factors that Increase Risk for Substance Use, Misuse, and Addiction Not all people use substances, and even among those who use them, not all are equally likely to become addicted. Many factors infuence the development of substance use disorders, including developmental, environmental, social, and genetic factors, as well as co-occurring mental disorders. Other factors protect people from developing a substance use disorder or addiction. The relative infuence of these risk and protective factors varies across individuals and the lifespan. Early Life Experiences 1 the experiences a person has early in childhood and in adolescence can set the stage for future substance use and, sometimes, escalation to a substance use disorder or addiction. See Chapter 1 Introduction and Early life stressors can include physical, emotional, and sexual Overview and Chapter 3 Prevention Programs and Policies. Research suggests that the stress caused by these risk factors may act on the same45 46 stress circuits in the brain as addictive substances, which may explain why they increase addiction risk. In addition, the brain undergoes signifcant changes during this life stage, making it particularly vulnerable to substance exposure. For example, a brain imaging study of adolescents revealed that the volume of the frontal cortex was smaller in youth who transitioned from no or minimal drinking to heavy drinking over the course of adolescence than it was in youth who did not drink during adolescence. Genetic and Molecular Factors Genetic factors are thought to account for 40 to 70 percent of individual differences in risk for addiction. Some of these variants have been associated with the metabolism of alcohol and nicotine, while others involve receptors and other proteins associated with key neurotransmitters and molecules involved in all parts of the addiction cycle. Genes involved in strengthening the connections between neurons and in forming54 drug memories have also been associated with addiction risk. Additional research on the mechanisms underlying gene by environment interactions is expected to provide insight into how substance use disorders develop and how they can be prevented and treated. Use of Multiple Substances and Co-occurring Mental Health Conditions Many individuals with a substance use disorder also have a mental disorder,57,58 and some have multiple substance use disorders. One reason for the overlap may be that having a mental disorder increases vulnerability to substance use disorders because certain substances may, at least temporarily, be able to reduce mental disorder symptoms and thus are particularly negatively reinforcing in these individuals. Second, substance use disorders may increase vulnerability for mental disorders,62-64 meaning that the use of certain substances might trigger a mental disorder that otherwise would have not occurred. As these possibilities are not mutually exclusive, the relationship between substance use disorders and mental disorders may result from a combination of these processes. Regardless of which one might infuence the development of the other, mental and substance use disorders have overlapping symptoms, making diagnosis and treatment planning particularly difcult. For example, people who use methamphetamine for a long time may experience paranoia, hallucinations, and delusions that may be mistaken for symptoms of schizophrenia. And, the psychological symptoms that accompany withdrawal, such as depression and anxiety, may be mistaken as simply part of withdrawal instead of an underlying mood disorder that requires independent treatment in its own right. Given the prevalence of co-occurring substance use and mental disorders, it is critical to continue to advance research on the genetic, neurobiological, and environmental factors that contribute to co-occurring disorders and to develop interventions to prevent and treat them. Biological Factors Contributing to Population-based Differences in Substance Misuse and Substance Use Disorders Differences Based on Sex Some groups of people are also more vulnerable to substance misuse and substance use disorders. For example, men tend to drink more than women and they are at higher risk for alcohol use disorder, although the gender differences in alcohol use are declining. They also report worse negative affects during withdrawal and have higher levels of the stress hormone cortisol. Female rats, in general, learn to self-administer drugs and alcohol more rapidly, escalate their drug taking more quickly, show greater symptoms of withdrawal, and are more likely to resume drug seeking in response to drugs, drug-related cues, or stressors. The one exception is that female rats show less withdrawal symptoms related to alcohol use. Differences Based on Race and Ethnicity Research on the neurobiological factors contributing to differential rates of substance use and substance use disorders in particular racial and ethnic groups is much more limited. Although these effects may protect some individuals of East Asian descent from alcohol use disorder, those who drink despite the effects are at increased risk for esophageal76 and head and neck cancers. Another study found that even low levels of alcohol consumption by Japanese77 Americans may result in adverse effects on the brain, a fnding that may be related to the differences in alcohol metabolism described above. Additional research will help to clarify the interactions between race,78 ethnicity, and the neuroadaptations that underlie substance misuse and addiction. This work may inform the development of more precise preventive and treatment interventions.

Persistent infection with a high-risk virus (especially type 16) can cause cancer of the cervix, vulva, vagina, anus, penis, and 10 oropharynx. One of the reasons, among others, for the increase in the infection lies in the rise of sexual initiation at very early ages and to have an important and promiscuous sexual activity. The most recent Spanish figures (April 2017) indicate that the percentage of women aged 15 who have had sex is 19%; and the average age range at the time of first intercourse is between 16. The best known are genotypes 16 and 18, since they are linked to the development of cervical cancer, is the second most common cancer in women after breast cancer. In fact, it has been demonstrated that there is a link between the high prevalence of cervical cancers and infections 3, 6 with this virus. Therefore, the goals of ozone therapy are to: Prevent the virus from multiplying and infecting new cells. Favor the immune response of the T cells dependent, as well as the humoral response B dependent, thanks to a better presentation of antigens. Rebalance the immune response by controlling persistent infection and related diseases. Neutralize the production of viral oncoproteins, involved in the origin and progression of the neoplastic process. The research protocol was discussed by the participating researchers and reviewed and approved by the Ethics and Institutional Review Committee (Fiorela Clinic). Once the committee determined that the research complied with the ethical procedures for medical research in 13 humans set up by the Helsinki Declaration issued by the World Medical Assembly the protocol started to be applied. Ozone group (patients treated exclusively with ozone) (n = 10): It received only 10 ozone vaginal insufflations with the same concentrations used in the previous group and that are specified below. Vaginal insufflation through a vaginal device at concentration of 20 fig/mL O2 / O3, at continuous flow of 200 mL/min during 10 min.

The evaluation of the efficacy of the treatment was concluded with vaginal cytology three months after the last therapy. An exploratory analysis of the data was performed to detect aberrant points (outliers). The experimental data were subjected to a descriptive analysis where the proportions of the main variable (success or failure) were estimated.

More than 85 well characterised genotypes are recognised, and more than 120 have been tentatively identified (zur Hausen 1999). These epidemiological characteristics are consistent with a sexually transmitted disease. This demographic transition has already taken place in the Western countries of the world. Lack of reliable data on the magnitude of chronic diseases in India has been a major limitation in assigning their priorities in health care and medical research. The pattern of cancer in India shows a predominance of tobacco related cancers in men. The programme envisages control of tobacco related cancers, early diagnosis and treatment of uterine cervical cancer and distribution of therapy services and palliative care through augmentation of health infrastructure. These data have been the main resource for initiating cancer control programs in Kerala. Risk factors for common cancers in the hospital cancer registry were reported (Sankaranarayanan et al. Pap smear based cytology screening has been the recommendation for the prevention of invasive cervical cancer and several agencies and countries have accepted this strategy. The effectiveness of organised cytology screening programmes has been well demonstrated by the Finnish mass screening system. The incidence of cervical cancer in Finland decreased from 15/100,000 in 1963 when screening was introduced to 2. Improvements in living standards and empowering women are the prerequisites for cervical cancer control in India (Varghese et al. With this background a study was carried out in the suburbs of Trivandrum, the capital of Kerala State, to address the prevalence and determinants of Human Papillomavirus. The (E) region proteins are associated with cell transformation and viral gene regulation and are most critical in the pathogenesis of invasive cancer. These factors point towards the likelihood for a sexually transmittable agent in the aetiology of carcinoma of the cervix. The religious practice of circumcision of males was considered as a protective factor among Jews and Muslims (Brinton and Fraumeni 1986). The role of a male factor in cervical cancer was noted from the studies showing geographic clustering of cervical cancer and penile cancer (Li et al. Risk of cervical cancer was found to be increased significantly in women whose male partners have reported multiple partners (Brinton et al. Smoking also had been considered as a risk factor for cervical cancer (Winkelstein 1977). However in India, which is a high incidence region for cervical cancer, tobacco smoking in women is extremely rare. In bacterial vaginosis, the lactobacilli-dominated flora is replaced by an abundant complex flora, constituted by gardenella, micrococci, streptococci and staphylococci. The age specific incidence rates of preinvasive lesions are not usually collected. The sequence in time at which they attain the peak supported the successive progression (Storm et al. The protein E6 transforms cells by binding the cellular tumour suppresser and regulatory protein p53, leading to rapid degradation of p53. This finding supports the prevention of squamous cell carcinoma of the cervix by vaccination. Kazhakuttom Panchayat (one of the administrative units) and Maryandu village, (15 Kilometres away from the Regional Cancer Centre) (Figure 2). Kazhakuttom Panchayat was selected for operational and logistic convenience as well as for the fact that this area had a good representation of the three major religious groups in Kerala. The addresses of all the households in these regions were available at the Panchayat office (administrative office), the reliability of which was not certain. Pilot phase A pilot study was conducted between March and August 1993 to assess the feasibility. The list of houses maintained in the Panchayat office was utilised to identify the eligible population during the pilot phase. Attendance at these clinics was not restricted to any defined population and women from outside the study area also visited the clinic. It was realised from the pilot phase that the list of addresses in the administrative office was not adequate and unique identification of an individual was not possible. Hence, considering the logistic aspects, the study was conducted in the following way. Information was collected on a household survey form (Appendix 1), which contained details of the ownership of the house, members of the household, their age, marital status, and relationship to the head of the household. The enumeration of the entire study area took 9 months to complete and details of all the households were entered into the computer. This unique identification number was used in all the forms and data entry programmes for linkage purposes. Pamphlets describing the study and the procedures were distributed through various local groups (Appendix 3). All religious organisations and political parties were approached to gain the confidence of the community. These centres were sometimes situated at places remote from where the people resided and women were not happy to walk long distances to attend the clinic. Medical consultation the medical officer of the team provided prescriptions for the women and sometimes for the family members who accompanied these women. The medical officer was available in the field office every day and women were asked to see the doctor if they had any complaints. Data collection Women who attended the clinics with their identification cards were matched with the computer list. An informed consent form in vernacular (Appendix 2) was given which explicitly mentioned the biological sample collection. Gynaecological symptoms and temporary contraceptive measures were asked over a reference period of one year. This was mainly due to logistic reasons as such a questionnaire in the beginning would have been difficult to administer. Men were not available to be interviewed and their behaviour was also enquired from their wives. The first sample from the spatula was dissolved in a phosphate buffered saline solution and placed in ice packs immediately. The next sample was smeared onto glass slides, which were marked with the unique identification numbers. Cytology smears were received in the cytopathology division for staining and reading. The results of these analyses were then linked to the database on interview schedules using unique identification numbers. The probes used were biotin-labelled and positive hybridisation was detected using enhanced chemiluminecence. Samples giving a positive signal with the generic probe but which were negative on all dot blots were considered positive but untyped. Based on these combinations, three levels of (low, middle and high) social class were generated. Instead of age at menarche and age at marriage, this variable (menarche-marital difference) was used for further analyses.

The associated costs also may be reduced available and distributed earlier in the pandemic. Modeling studies tify cases early enough to administer antivirals from the 2009 influenza pandemic investigated the efficaciously. Those studies found that vaccinating high-risk individuals was more cost-effective than prioritizing Cost-Effectiveness children. However, these studies did not following interventions among the general population account for the indirect costs of school closures and had the potential to provide cost savings: vaccines, antiabsenteeism. Consideration of these factors could reveal viral treatment, social distancing, antiviral prophylaxis increased cost savings from vaccinating children. Vaccines for a novel influenza virus can take several Depending on the characteristics of a pandemic and months to develop, and vaccines for other pathogens how mitigation efforts are implemented, some mitiga(for example, Ebola and Zika) can take even longer to tion strategies could become highly cost-ineffective.

Less noticed was the likelihood that a pandemic with characteristics similar to the 1918 influenza pandemic would have killed about 10 times as Value of Lives Lost and Illness Suffered many people in Liberia, Guinea, and Sierra Leone as did the second major dimension of loss from a pandemic Ebola. The global death total from such a pandemic lies in the intrinsic value of lives prematurely lost and of could be 2,500 times higher than the World Health illness suffered. Nevertheless, extensive empirical findings appear in the economics literature, particularly for losses from premature mortality (Hammitt and Economic Loss Robinson 2011; Lindhjem and others 2011; Viscusi In addition to the enormous loss in terms of human 2014). This chapter estimates the magnitude of these losses (Burns, Mensbrugghe, and Timmer 2008; this dimension of loss from pandemic influenza using Jonas 2013) and found that a pandemic of the severity of standard methods. McKibbin and Sidorenko (2006) examined expressed as the fraction of the world population that Corresponding author: Victoria Y. The estimated loss is relative We define severe pandemics as having mortality rates of to the counterfactual of no risk (r = 0). The historical record suggests that the 1918 influenza pandemic was an outlier, with unusual circumstances, including the co-occurrence of World War I. Fauci (2017) point to long-term morbidity and disability In 1918, 20 million deaths would constitute 1. It uses an expected value frameWe searched PubMed and Google Scholar for all work to estimate losses from an uncertain and studies on influenza epidemics and pandemics. We found three studies that examined loss in national income from influenza pandemics of varying Implications of All of the Available Evidence severity. This finding points to the need estimates of the magnitude of pandemic risk were for more attention to pandemic risk in public polfound in only two sources, both partially icy and to the value of enhanced understanding proprietary. Lowand middle-income countries Added Value of this Study would suffer more than high-income countries in this study provides the first assessment of the mortality losses. Further studies to investigate the expected value of losses from pandemic influenza potential losses from pandemics from other causes and, specifically, the value of intrinsic losses from are ongoing. The table includes pandemics dating from 1700 to 2000 for which severity could be ascertained from the literature. Morens and Fauci (2004) and Morens and Taubenberger (2011) identify 12 to 17 pandemics in the period from 1700 to 2000, but many of those resulted in lower mortality than those in this table (or had mortality levels that could not be ascertained). Although the world may be expected to experience rather to select plausible values from that literature to moderately severe to severe pandemics several times define reference cases. With Taubenberger and others each century, there is consensus among influenza experts (2007), we emphasize the uncertainty inherent both in that an event on the very severe scale of the 1918 panthe history and in projections drawn from it. In light of demic may be plausible but remains historically and this literature and its attendant uncertainty, we develop biologically unpredictable (Taubenberger, Morens, and and report results for two representative levels of severFauci 2007). First, information on missible and virulent viruses could lead to global death pandemic severity is used to generate increases in rates substantially higher than in 1918 (McKibbin and age-specific death rates for the world and for each of the Sidorenko 2006; Osterholm 2005). Second, In general, lower-income areas of the world suffered the literature on valuation of changes in mortality rates disproportionately in 1918; in particular, India suffered is used to generate estimates of the age-specific losses a major share of global pandemic mortality (Davis from mortality increase and, by extension, of total loss. Estimates of the age-specific excess mortality rate in 1918 was low, probably because of lower case ity rates of different populations from the 1918 fatality rates rather than lower incidence rates (Cheng pandemic are consistent in their form of a unique and Leung 2007). This finding points to the possibility of inverted U-shaped distribution, whereby adults ages heterogeneity between countries of comparable national 15 to 60 years experienced elevated rates compared to income levels in a modern pandemic. The average severity of a pandemic in a given severity range is the expected value of severity given that a pandemic did in fact occur in that range. Let s*(x) be the contribution of If we had access to a function r(s) showing exceedance probability as a function of severity, our analypandemic severity greater than x to expected pansis could proceed using the expected value of severity demic severity. For the first step in our tary cumulative distributions provides natural canassessment of expected severity, we use recent history didates for r(s), and we parameterize the hyperbolic as a straightforward guide to frequency and severity in terms of its expectation and the fatness of its tail box continues next page 350 Disease Control Priorities: Improving Health and Reducing Poverty Box 18. However, for s = 4 in the United the fatness of the tail (smaller values imply a fatter States (over 7 million deaths worldwide), the expotail). We estimates (Madhav and others 2018) of exceedance infer global severity from the severity in the United probability and pandemic risk that use methods States using the approach described in the main text. Substantially greater severities severity for the United States of such a pandemic of and likelihoods have been discussed by Madhav 8. The fatality rate among Using the age distributions of populations and the young adults, although high in the 1918 influenza panlife tables from the World Population Prospects of the demic, was relatively low in the 1957 and 1968 epidemUnited Nations Population Division (2015), we calculate ics (Simonsen and others 1998). We also use an excess deaths and the estimated reduction in life expecalternative and more typical distribution of excess tancy based on these age-specific mortality rates mortality, where young children and elderly persons (Preston, Heuveline, and Guillot 2000). Our expected of the two, assuming the same proportional increase in annual pandemic death total across both severities is mortality for all age groups. Relative severity indicates severity in each income group relative to the high-income group. Our specific calculations followed the methods used in Global Health 2035 (Jamison and others 2013). In calculating the income loss figures as expected annual values but uses value of change in mortality at age, we used as a reference different values for annual pandemic risk. This amount was adjusted up or down for loss for the world as a whole from the intrinsic loss from ages other than 35 years in proportion to the ratio of life pandemic risk to be -0. The dominant position in the literature is that lower-income countries should have lower values for v (Hammitt and Robinson 2011). The literature provides weak quantitative guidance on how v should vary with y, if at all, and the numbers we have chosen should be viewed as reasonable assumptions within the spirit of the literature. Very substantial uncertainty adheres to these cost estimates (see note a, table 18. For any given value of s, our calculation of the value of intrinsic loss from a pandemic depends on the age distribution of deaths from the pandemic, and the calculations reported here use different age distributions for pandemics of different severities. In particular, for moderately severe pandemics, we assume an older age distribution of deaths, typical of such pandemics. For severe pandemics, we assume the younger age distribution of deaths that characterized the 1918 pandemic. In contrast to the modest nummates in the literature of the income loss from pandember of studies on potential pandemic loss, there are hunics of differing levels of severity (Burns, Mensbrugghe, dreds of studies on the cost of climate change and the and Timmer 2008; Jonas 2013; McDonald and others social cost of carbon (Pizer and others 2014; Tol 2013). Though our severGlobal carbon dioxide emissions were on the order of ity categories differ from theirs, the values of 1 percent of 36,000 million tons in 2013, containing 6,200 million global income from a moderately severe pandemic and tons of carbon (Global Carbon Project 2015).

The synthesis of the 2014 report of the which 95 percent is from severe pandemics. In comparison, our expected annual Expected annual pandemic losses appear substantial. Modest reductions in Sensitivity to Assumptions cold-related mortality and morbidity will be offset by the magnitude and severity of the increased risks. However, the gradual nature of often an ineffective substitute for dimensions of human warming allows time for costly adaptations that could well-being. In practice, however, these estimates are be expected to reduce the mortality consequences. A obtained from ex post observations of the labor market recent paper points to potentially important mortality and reflect the way people differentially value and trade off reductions in the United States resulting from efforts to very small fatality risks for income. These benefits at a given age in the United States and in the way the valappear to flow almost entirely from reduced pollution uation (v) should vary across ages and countries (Hammitt rather than slower atmospheric warming.

Another useful comparator for pandemic risk lies in Hammitt and Robinson (2011) have assembled the deaths from selected alternative causes.
