SARS-CoV-2 in the context of past coronaviruses epidemics: Consideration for prenatal care.

Since December 2019, the novel SARS-CoV-2 outbreak has resulted in millions of cases and more than 200 000 deaths worldwide. The clinical course among nonpregnant women has been described, but data about potential risks for women and their fetus remain scarce. The SARS and MERS epidemics were responsible for miscarriages, adverse fetal and neonatal outcomes, and maternal deaths. For COVID-19 infection, only nine cases of maternal death have been reported as of 22 April 2020, and pregnant women seem to develop the same clinical presentation as the general population. However, severe maternal ca…

Эпидемии и вспышки периферийных расстройств нервной системы: I. инфекционные и иммунизированные причины.

История человечества характеризуется многочисленными эпидемиями, некоторые из которых связаны с заболеваниями периферической нервной системы, как инфекционными, так и другими. Здесь мы описываем три основные инфекционные причины эпидемий, которые влияют на периферию нервной системы: проказу, полиомиелит и дифтерию. Затем мы обсуждаем основные эпидемии иммунного происхождения.

The history of mankind is marked by numerous epidemics, some of which involved diseases of the peripheral nervous system, either infectious or otherwise. We describe here the three main infectious causes of epidemics that affect the peripheral nervous system: leprosy, poliomyelitis and diphtheria. We then discuss the main epidemics of immune-mediated origin.

Risk perception and behavioral change during epidemics: Comparing models of individual and collective learning.

Modern societies are exposed to a myriad of risks ranging from disease to natural hazards and technological disruptions. Exploring how the awareness of risk spreads and how it triggers a diffusion of coping strategies is prominent in the research agenda of various domains. It requires a deep understanding of how individuals perceive risks and communicate about the effectiveness of protective measures, highlighting learning and social interaction as the core mechanisms driving such processes. Methodological approaches that range from purely physics-based diffusion models to data-driven environm

The Opioid Hydra: Understanding Overdose Mortality Epidemics and Syndemics Across the Rural-Urban Continuum.

The rapid increase of fatal opioid overdoses over the past two decades is a major U.S. public health problem, especially in non-metropolitan communities. The crisis has transitioned from pharmaceuticals to illicit synthetic opioids and street mixtures, especially in urban areas. Using latent profile analysis, we classify n = 3,079 counties into distinct classes using CDC fatal overdose rates for specific opioids in 2002-2004, 2008-2012, and 2014-2016. We identify three distinct epidemics (prescription opioids, heroin, and prescription-synthetic opioid mixtures) and one syndemic involving all o…

Health Disparities and Converging Epidemics in Jail Populations: Protocol for a Mixed-Methods Study.

BACKGROUND: Incarcerated populations have increased in the last 20 years and >12 million individuals cycle in and out of jails each year. Previous research has predominately focused on the prison population. However, a substantial gap exists in understanding the health, well-being, and health care utilization patterns in jail populations. OBJECTIVE: This pilot study has 5 main objectives: (1) define recidivists of the jail system, individuals characterized by high incarceration rates; (2) describe and compare the demographic and clinical characteristics of incarcerated individuals; (3) identi

Historical Perspective of Arboviruses in Mozambique and Its Implication for Current and Future Epidemics.

Mozambique is a tropical country situated in the Southern part of Africa, a region where data on the burden and epidemiology of arbovirus is presently quite scarce although the frequency of outbreaks caused by arboviruses is rapidly increasing. Outbreaks of dengue fever have been reported in Mozambique, Angola and Tanzania and a recent unprecedented outbreak of Yellow fever has been recorded in Angola. These new outbreaks collectively suggest that arboviruses, and specifically flavivirus infections, are endemic in Mozambique.Although recent data on arbovirus activity is scarce, the work of Kok

Recalibration of the Grunow-Finke Assessment Tool to Improve Performance in Detecting Unnatural Epidemics.

Successful identification of unnatural epidemics relies on a sensitive risk assessment tool designed for the differentiation between unnatural and natural epidemics. The Grunow-Finke tool (GFT), which has been the most widely used, however, has low sensitivity in such differentiation. We aimed to recalibrate the GFT and improve the performance in detection of unnatural epidemics. The comparator was the original GFT and its application in 11 historical outbreaks, including eight confirmed unnatural outbreaks and three natural outbreaks. Three steps were involved: (i) removing criteria, (ii) cha…

Timing of influenza epidemics and vaccines in the American tropics, 2002-2008, 2011-2014.

BACKGROUND: Influenza-associated illness results in increased morbidity and mortality in the Americas. These effects can be mitigated with an appropriately chosen and timed influenza vaccination campaign. To provide guidance in choosing the most suitable vaccine formulation and timing of administration, it is necessary to understand the timing of influenza seasonal epidemics. OBJECTIVES: Our main objective was to determine whether influenza occurs in seasonal patterns in the American tropics and when these patterns occurred. METHODS: Publicly available, monthly seasonal influenza data from t…

HIV infection among persons who inject drugs: ending old epidemics and addressing new outbreaks.

AIDS among persons who inject drugs, first identified in December 1981, has become a global epidemic. Injecting drug use has been reported i … eview examines possible processes through which combined prevention programs may lead to ending HIV epidemics. However, notable outbreaks of HIV among persons who inject drugs have recently occurred in several countries, including in Athens, Greece; Tel-Aviv, Israel; Dublin, Ireland; as well as in Scott County, Indiana, USA. This review also considers diffe …

Climatic and evolutionary drivers of phase shifts in the plague epidemics of colonial India.

Immune heterogeneity in wild host populations indicates that disease-mediated selection is common in nature. However, the underlying dynamic … ue-resistant phenotype had become prevalent among commensal rats of cities undergoing severe plague epidemics. To understand the possible evolutionary basis of these observations, we developed a mathematical model coupling environmentally forced plague dynamics with evolutionary selection of rats, capitalizing on extensive archival data from Indian Plague C …

[Isothiazolinones as causal factors of contact allergy epidemics in the 20th and 21st centuries].

Chloromethylisothiazolinone (MCI) and methylisothiazolinone (MI) have been widely used as preservatives in cosmetics, household products and industrial products since the late 1970s. First cases of contact allergy to the MCI/MI combination were noted in 1980-1982 in Sweden. Then, a significant increase in the frequency of sensitization to these compounds was observed in many European centers. The increase has been stopped by the introduction of legislation on their maximum concentrations in consumer and industrial products in Europe and in some non-European countries. But approval of the use o

[Epidemics in the news in Portugal: cholera, plague, typhus, influenza and smallpox, 1854-1918].

In severe health crisis like those of 1854-1856, 1899 and 1918, especially in Porto, where cholera morbus, the bubonic plague, typhus fever, pneumonic influenza and smallpox killed high percentages of the population, the images of the epidemics in the press enable us to identify the scientific knowledge in a country considered peripheral, but which had studies and personnel specialized at the most advanced levels for the time. A database of 6,700 news items and announcements reveals the medical and pharmaceutical knowledge of the second half of the nineteenth and early twentieth centuries, the…

Definition and characterization of localised meningitis epidemics in Burkina Faso: a longitudinal retrospective study.

BACKGROUND: The epidemiology of meningococcal meningitis in the African meningitis belt is characterised by seasonality, localised epidemics and epidemic waves. To facilitate research and surveillance, we aimed to develop a definition for localised epidemics to be used in real-time surveillance based on weekly case reports at the health centre level. METHODS: We used national routine surveillance data on suspected meningitis from January 2004 to December 2008 in six health districts in western and central Burkina Faso. We evaluated eight thresholds composed of weekly incidence rates at health…

Simultaneous epidemics of influenza and malaria in the Australian Army in Palestine in 1918.

In October 1918, an Allied army (Egyptian Expeditionary Force) in Palestine experienced simultaneous epidemics of falciparum malaria and influenza during the cavalry campaign that defeated the Turkish Army. Malaria infection occurred 2 weeks after the advance of cavalry units into areas without environmental mosquito control. Pandemic influenza, now thought to be an A/H1N1 strain, struck at the same time. In the Egyptian Expeditionary Force of 315,000 soldiers, 773 died from malaria and 934 from influenza-pneumonia. Disease casualties outnumbered those due to combat by more than 37 to 1. Simul…

Epidemics of vector-borne diseases observed in infectious disease surveillance in Japan, 2000-2005.

BACKGROUND: Observing the epidemics of vector-borne diseases is important. One or more cases of 6 vector-borne diseases were reported to the National Epidemiological Surveillance of Infectious Diseases in Japan in 2000-2005. METHODS: The reports of those cases were available. The incidence was observed by region of acquired infection, prefecture reporting, and week and year of diagnosis. RESULTS: The incidence rate per year per 1,000,000 population was 0.36 for dengue fever, 0.04 for Japanese encephalitis, 0.38 for Japanese spotted fever, 0.08 for Lyme disease, 0.74 for malaria, and 3.50 for…

Measuring trends in prevalence and incidence of HIV infection in countries with generalised epidemics.

OBJECTIVE: Review of recent data and practice to derive guidance on questions relating to the measurement and analysis of trends in HIV prevalence and incidence. RESULTS: HIV prevalence among pregnant women attending antenatal clinics (ANCs) remains the principal data source to inform trends in the epidemic. Other data sources are: less available, representative of a small section of the population (sex workers, occupational groups), subject to additional bias (for example, voluntary counselling and testing service statistics), or are not yet available for multiple years (national surveys). V

Estimation of infectious disease parameters from serological survey data: the impact of regular epidemics.

Serological surveys are a useful source of information about epidemiological parameters for infectious diseases. In particular they may be u … or to the introduction of the combined measles, mumps, rubella (MMR) vaccine. We conclude that past epidemics have only a marginal effect on estimates, and that standard methods that do not adjust for regular epidemics are valid.

Predicting St. Louis encephalitis virus epidemics: lessons from recent, and not so recent, outbreaks.

St. Louis encephalitis virus was first identified as the cause of human disease in North America after a large urban epidemic in St. Louis, … rsely impacted tourism in the affected region. The accurate forecasting of mosquito-borne arboviral epidemics will help minimize their impact on urban and rural population centers. Epidemic predictability would help focus control efforts and public education about epidemic risks, transmission patterns, and elements of personal protection that reduce the pro …
