Zika outlook less dire as disease wanes in Southern Hemisphere

New cases of Zika transmission are declining in Caribbean and South American countries that were hardest hit by the mosquita-bourne virus according to public health officials, the Houston Chronicle reports.

Peter Hotez, fellow in disease and poverty, said while Texas does not have enough disease surveillance in place to detect whether the virus is still present after a local transmission in South Texas last year, he stated that Zika probably will not be brought into the U.S. this summer.

“The sources of last year's epidemic are largely gone,” Hotez said."There's less virus circulating in the Southern Hemisphere to be imported and introduced into places like Texas and Florida."
