From California Department of Public Health: Spring Break Travelers Reminded to Protect Themselves against Zika
CDC Considers Travel to Mexico, Latin America a Potential Risk for Infection

Sacramento, CA – March 20th, 2017

The California Department of Public Health (CDPH) advises spring break travelers vacationing in warmer climates to protect themselves from mosquito bites and avoid unprotected sex in areas with known transmission of the Zika virus.

“Spring break is the perfect time to have fun in the sun, but it is important that people take precautions to prevent Zika,” said CDPH Director and State Public Health Officer Dr. Karen Smith. “Unfortunately, the mosquitoes that spread Zika enjoy warm weather too.”

Rainy Weather and Mosquitoes

Do wet or dry years create more mosquito problems?  One might immediately assume wet years because mosquitoes need water to breed.  On the other hand, droughts create pools and puddles in water bodies like rivers and streams that would otherwise be flowing too strongly for mosquitoes to utilize.  The reality is both weather patterns cause different types of mosquito control challenges.
