Texas reported its first home-grown case of Zika virus infection Monday — making it the second U.S. state with mosquitoes spreading the virus.

It's a long-feared development but not a surprising one. Like Florida, South Texas is home to the Aedes aegypti mosquitoes that spread Zika and also hosts many travelers to and from countries where the virus has been spreading.

Zika has been sweeping through Latin America and the Caribbean in recent months, and the fear is that it will get worse there and arrive in the U.S. with the onset of mosquito season this summer. John Mone / AP
