Penn State Global Programs is issuing advice to travelers about the risks of mosquito-borne illnesses, like Zika, based on the latest information from the Centers for Disease Control and Prevention. Penn Staters are currently traveling to affected areas and are likely to continue to do so. Officials, however, say Zika is not the only concern, as travelers should take simple precautions to prevent all mosquito-borne illnesses — such as Zika, dengue or chikungunya viruses.
Daytime temperature fluctuations greatly alter the incubation period of malaria parasites in mosquitoes and alter transmission rates of the disease. Consideration of these fluctuations reveals a more accurate picture of climate change's impact on malaria. Most studies use average monthly temperatures to study the impact of climate change on the global malaria burden," said Matthew Thomas, professor of entomology, Penn State. "But mosquitoes and the malaria parasites developing within them do not experience average temperatures; they are exposed to temperatures that fluctuate throughout the day."
