Yes, once you’re infected you’re immune to the virus. With the Rio Olympics starting Friday in the country where over 165,000 suspected Zika cases have been reported this year, and local mosquito-borne Zika virus transmission reported in Florida, it’s natural to be concerned about the infectious disease that’s been dominating headlines. That being said, one of Hotez's biggest worries is Zika cases that aren’t being reported. Guillen-Barre is rare and is found in 1 in 1,000 Zika patients, with some estimating 1 in 500 cases, Hotez said. Certain areas of the country, specifically Florida and the Gulf Coast, particularly Louisiana and Texas, have a high concentration of the Aedes aegypti mosquito and may be more at risk of a Zika virus outbreak.
