While a solitary case of travel-related Zika virus infection was reported in Bulloch County Wednesday, local city and health officials say there is no cause for panic. Measures to prevent Zika and other mosquito-borne viruses have been in place for some time, and the mosquitoes that carry the virus have not been detected anywhere in Georgia, officials say. While little information is being released about the person in Bulloch County who contracted the virus, health officials said it is important to know the case is travel related, meaning the virus was contracted elsewhere.
