About 40% of the world’s population lives in the tropical zone. The tropical climate is warm to hot and moist year around. As a result, exotic disease is mostly reported in tropical areas. In addition, large volumes of rains favor the formation of breeding grounds and high number and variety of natural reservoirs and presence of insect vectors of diseases. Higher temperatures may favor the replication of pathogenic agents both inside and outside the body of organisms. In comparison, in the temperate zone \,disease are less prevalent because of cold season; insects go in hibernation during the cold season and thus their population growth is arrested to some extent.
Increase in global temperature is causing tropical disease and vectors to spread to higher altitudes in mountainous region and to higher latitudes that were previously spread. Thus, the tropics with their biodiversity and favorable climate for microbial growth and the evolution are the potential place for the emergence of new disease. So, it can be safely concluded that future hot spots for occurrence of new disease are more likely to be found in the wildlife rich and the population dense tropics, especially in the highly populated cities.
Countries of southern Asia and Southeast Asia are tropical countries rich in biodiversity overpopulated. Hence, these countries too are at risk for emergence of new disease. India too cannot escape the specter of the appearance of new bugs. And hence Nepal is also at risk because of the open border with India.
