A locally transmitted case means that the person who got the Zika virus did not get it by traveling to a place where it is commonly found nor did the person have sex with someone who has the virus. She also did not get it through a blood transfusion or in a lab setting. In other words, it was most likely spread by an infected mosquito.
Texas health officials have set up surveillance sites in the Brownsville area where the infected woman lives, to test mosquitoes for possible infection. They are also trying to find out if anyone else in the area has been infected with the virus.
CDC Director Tom Frieden, M.D., M.P.H. said “Even though it is late in the mosquito season, mosquitoes can spread Zika in some areas of the country. Texas is doing the right thing by increasing local surveillance and trapping and testing mosquitoes in the Brownsville area.”
The CDC’s press release states: “As of Nov 23, 2016, 4,444 cases of Zika have been reported to CDC in the continental United States and Hawaii; 182 of these were the result of local spread by mosquitoes. These cases include 36 believed to be the result of sexual transmission and one that was the result of a laboratory exposure. This number does not include the current case under investigation in Texas.”
Now that the cold weather has arrived, you may think that the Zika virus is a thing of the past. But, this announcement of a likely locally transmitted case of Zika should be a reminder that Zika is still here, and it is still a threat.
