RETRACTED: Climate Change and Emerging and Re-Emerging Tropical Infections

Abstract

Continual changes in climate have become a globally alarming phenomenon. Evidence showed that temperature is increasing from time to time globally, linked to the growing concentration of atmospheric energy-trapping gases, potentially creating the so-called greenhouse effect. Greenhouse gases comprise mainly carbon dioxide, N2O, methane, and other halocarbons. A remarkable upsurge in greenhouse gas levels was noticed around the 18th century, when the industrial era started. Climate change influences the health of humans and animals. The relationship between climate and health has been a subject of study for a very long time; however, the development of modern tools and technologies has led to fascinating annotations glimmering new insights into the role of the environment, including weather and climate, in infectious disease dynamics. Suitable climate and weather situations are required for the persistence, multiplication, distribution, and spreading of disease pathogens, vectors, and hosts. Hence, changes in climate or weather situations may influence transmittable diseases by affecting the pathogens, vectors, hosts, and their living milieu. This chapter highlights the effect of climate change on the emergence and/or reemergence of selected disease models.
