Climate change will cause 60,000 deaths in 2030. Researchers warn that poor air quality can cause 260,000 premature deaths by the year of 2100

Rising temperatures go to accelerate chemical reactions that create air pollutants such as ozone and affect public health. Dryer sites also suffer from intense air pollution due to less rainfall and more occurrence of fires.

In addition, trees will also be affected by higher temperatures, emitting a higher volume of pollutants organic. Climate change should also reach health through changes in thermal stress, access to safe water and food, severe storms and spread of infectious diseases.

For the analysis, the researchers used a set of mathematical models on climate to determine the number of deaths due to the pollutants in 2030 and 2100. In each sample, the team evaluated projected changes in ground-level air pollution that could be attributed to future climate changes, in addition to population growth.

The results indicated that all regions of the world, with the exception of Africa, will have a high death toll from air waste. Specifically, five in eight models predicted that there will be more premature deaths by 2030 and seven of nine models by 2100. "Our finding is the clearest sign that climate change is detrimental to air quality and health," West said. "We also have the collaboration of some of the world's leading climate modeling groups in the United States, the United Kingdom, France, Japan and New Zealand, making this study the most comprehensive yet," said West. By 2015, air pollution has caused more than 4 million deaths worldwide, according to the Institute of Health Effects. Heavy and polluted air is equivalent to three or four cigarettes a day, and even if you are not a smoker, it is impossible to leave of breathing and to prevent poisonous smoke from flowing into the lungs.

Pollution is related to the increase in the occurrence of other cardiorespiratory diseases, such as cardiac arrhythmia, increased attacks of hypertension, myocardial infarction arteriosclerosis, angina, stroke and other diseases linked to decreased blood circulation. The incidence of lung cancer is also related to poor air quality.

For analysis, the team infected mosquitoes in the laboratory with all three virus types. Then they performed tests to verify the rate of transmission. The results showed that viruses can reproduce without dominance of one or the other in the organism of Aedes aegypti. "Double infections in humans are quite common and may be even more common than we imagine in theory the mosquito can infect someone with multiple viruses at one go, "said Claudia Rückert, a postdoctoral fellow at the CSU's infectious disease and arthropod laboratory.

Inspire project seeks to accelerate the diagnosis of lung cancer

Lung cancer is the leading cause of death among men and the second among women in Brazil, according to the Ministry of Health. For a long time, the main factor to trigger lung cancer was smoking. It has not been an element of risk for developing the tumor, but it is not the only one. To get an idea lung cancer rates in non-smokers have doubled in the last 15 years, from 8% to 20 %.
