Question: The spread of infectious diseases is expected to increase with climate change, mainly because?

Warming climates increase the range within which a disease can find a home especially those transmitted by vactors mosquitoes and ticks that carry a pathogen from its primary host to its new victim. Climate change would directly affect disease transmission by shifting the vectors geographic range and increasing reproductive and biting rates and by shortening the pathogen incubation period.
