The AccuWeather Mosquito Zika Risk Index provides users with a new and informative way to quickly view the likelihood, at a particular location, of mosquitoes that could carry the Zika virus. A risk level (very low, low, medium, high) is generated by evaluating the historical habitat for the mosquito species most closely linked with Zika and the latest scientific research on how weather affects mosquitoes, combining it with AccuWeather's Day By Day 90-Day forecast. The number of reported cases, sourced from the Center for Disease Control (CDC), is provided to heighten the awareness in Zika prone areas.
