Over long periods of time, individuals and communities can adapt to their local climates. When both warmer and colder temperatures go above or below those norms rapidly, scientific evidence shows that people become vulnerable to associated health effects related to those extremes. Studies suggest th...at climate change will greatly increase the severity and frequency of extreme temperature conditions, leading to increases in temperature-related illness and death

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.

Cet article fait partie d’une série d’explications à propos de la mise au point et de la distribution des vaccins.
Les vaccins sont conçus pour vous conférer une immunité sans les dangers d’avoir contracté la maladie. Il est courant de ressentir quelques effets indésirables légers à modérés après avoir reçu un vaccin. Ils sont dus au fait que votre système immunitaire demande à votre organisme d'a...ugmenter le flux sanguin afin que davantage de cellules immunitaires puissent circuler, et il élève votre température interne afin de tuer le virus. Les vaccins nous aident à nous protéger contre les maladies, et ressentir des effets indésirables légers ou modérés après avoir reçu un vaccin est un signe que ce vaccin et notre système immunitaire fonctionnent.

Rapid Policy Brief Series Series 14: COVID-19 and hypertension
This paper summarizes the evidence about the health effects of air pollution from particulate matter and their implications for policy-makers, with the aim of stimulating the development of more effective strategies to reduce
air pollution and its health effects in the countries of eastern Europe,... the Caucasus and central Asia.

The document presents a systematic analysis of dietary risks and their health impacts in 195 countries from 1990 to 2017. It highlights that suboptimal diets, such as those high in sodium and low in whole grains, fruits, and vegetables, significantly contribute to non-communicable diseases like hear...t disease, stroke, and diabetes. The study emphasizes the urgent need for improved dietary habits and policy interventions to reduce diet-related mortality and morbidity globally.

Occupational exposures to respirable crystalline silica occur in a variety of
industries and occupations because of its extremely common natural occurrence and the wide uses of materials and products that contain it. At least 1.7 million U.S. workers are potentially exposed to respirable crystallin...e silica [NIOSH 1991], and many are exposed to concentrations that exceed limits defined by current regulations and standards.

Air pollution from road traffic is a serious health hazard, and people with preexisting respiratory disease may be at increased risk. We investigated the effects of short-term exposure to diesel traffic in people with asthma in an urban, roadside environment.
This American Thoracic Society Statement was prepared by a Committee of the Scientific Assembly on Environmental and Occupational Health at the request of the American Lung Association Occupational Health Expert Advisory Group to emphasize the continuing importance of silicosis as a major lung disea...se worldwide and the need for increasing efforts in prevention. Emphasis is placed on public health issues of silicosis rather than on important current research in pathologic mechanisms.
