Factors linked to chikungunya, dengue outbreaks discovered

Updated:7 years, 3 months ago

New Delhi, Jul 25 (ANI): In one of the largest studies of its kind, researchers analysed chikungunya and dengue outbreak data from 76 countries over a period of 50 years. They mainly focused on regions across the Indian Ocean that are hard hit by these and other mosquito-borne infectious diseases. The data revealed that population density and proximity to a country already experiencing an outbreak were the factors most closely associated with a country's own likelihood of experiencing an outbreak. The new study found no significant association between local temperature or precipitation and outbreak risk, a somewhat unexpected finding since heat, rain, and fluctuations in mosquito populations are often linked.
