The virus is primarily spread through the bite of an infected mosquito. “We strongly warn everyone – especially pregnant women or women planning to become pregnant – avoid traveling to countries where Zika virus is circulating. “With Kentuckians competing in and attending the 2016 Summer Olympics in Rio, Brazil this summer, we must remain vigilant and take steps to protect ourselves. This includes being knowledgeable about where the virus is spreading, consulting with a healthcare provider, and following public health recommendations to avoid mosquito bites,” said Dr. Hiram Polk, DPH commissioner.
