Changes in climate factors substantially affect reproduction, development, distribution and seasonal transmissions of malaria. It is estimated that for the cost of saving one life by cutting down on carbon, 78,000 lives may be saved annually by using mosquito nets, environmentally safe indoor DDT sprays, and subsidies for effective, new combination therapies.19Surveillance and preparedness have been major components of the malaria control strategy, adopted since 1992 by the World Health Organization (WHO). } box-shadow: 0 1px 3px rgba(0, 0, 0, 0.12), 0 1px 2px rgba(0, 0, 0, 0.24); In addition, new diseases are emerging in regions where they were previously not present. color: #009edb; Given all the additional challenges created by the COVID-19 pandemic, we should recognize and focus on the need to strengthen and mend family relationships. } An official website of the United States government. However, a limitation of these models is the application of a uniform malaria-pre-cipitation relationship to geographically diverse regions (1-3). /*line-height: normal !important;*/ Problem statement: Climate change is a global environmental change that is adversely affecting human health by causing various health impacts in countries throughout the world.Climate is the most influential driving force of vector-borne diseases such as malaria.

The average temperatures in 2020 were 1.2°C higher than in the pre-industrial period globally, and 2.2°C higher in Europe. Predictions are common that in the coming decades, tens - even hundreds - of millions more cases will occur in regions where the disease is already present, and that transmission will extend to higher latitudes and altitudes. } Nature 420(6916):627-628 12478282. .main-container.container { Areas shown in yellow indicate the current distribution of malaria.

Leading health experts are urging the government . Half of the world is now at risk for contracting malaria, and with warmer temperatures and variations in rainfall, researchers from the University of Florida expect that malaria vulnerable areas will change and the total transmission zone will expand. The proposed effects of rising global temperatures on the future spread and intensification of the disease, and on existing malaria morbidity and mortality rates, substantively influence global health policy. The Effect of Climate Change on Malaria.
