Vector-borne disease, the disease-causing microorganism is transmitted from an infected individual to another individual by an arthropod (e.g., mosquito, tick, etc.) or some other agent. Key VBDs of concern include malaria, Lyme disease, dengue fever, yellow fever, Hantavirus pulmonary syndrome, and several forms of encephalitis. Weather affects the timing and intensity of disease outbreaks. Within their temperature range of tolerance, mosquitoes will reproduce more quickly and bite more in warmer conditions. Warmer temperatures also allow the parasites within mosquitoes to mature more quickly, increasing the chances that the mosquito will transfer the infection. Several modeling studies have predicted that increasing temperatures will lead to the spread of malaria and other diseases into previously unaffected areas. Climate change may also affect the severity of the disease at a given location.
