MOSQUITO SEASONS CHANGE. SO DOES YOUR RISK.
MOSQUITO SEASONS CHANGE. SO DOES YOUR RISK. Mosquito populations rise and fall with temperature, rainfall, humidity, and local conditions. As mosquito numbers and infections increase, so can the opportunity for viruses to spread. Travel adds another pathway. An infected traveler can carry a virus across borders—and where the right mosquitoes are already present, local transmission can begin. Holiday travel connects the world faster than ever. Before you fly, check what is circulating now—not last year. Mosquitoes don’t need passports. Viruses travel with us.
