DALLAS – This 4th of July holiday weekend, Dallas County Health and Human Services (DCHHS) is stressing the importance of taking precautions to avoid exposure to mosquitoes that can carry West Nile and Zika viruses.
“A lot of Dallas County residents may be planning to be outdoors or travel this weekend, so we want to remind them to use personal protection to avoid exposure to mosquitoes,” said Zachary Thompson, DCHHS director.
DCHHS recommends the 4Ds to protect against mosquitoes:
While all 4Ds are important, draining or treating standing water is crucial to stop mosquitoes from breeding. Standing water can be treated with EPA-approved larvicides that are available for retail purchase. Larvicides are products used to kill immature mosquitoes before they become adults. Larvicides are applied directly to water sources that hold mosquito eggs, larvae, or pupae. When used well, larvicides can help reduce the overall mosquito burden by limiting the number of mosquitoes that are produced, according to the Centers for Disease Control and Prevention.
To date, more than 100 mosquito pools have tested positive for West Nile virus in Dallas County in 2016 and there have been no reports of human West Nile virus cases. There have been no reports of Zika virus being transmitted locally by mosquitoes, but citizens may be traveling to areas where Zika virus transmission is active and ongoing, which include Central and South America, and the Caribbean.
“Travelers need to take extra precautions to avoid mosquito exposure, especially pregnant women and women planning to get pregnant, and of course if you are staying in the area West Nile virus remains a threat,” said Dr. Christopher Perkins, DCHHS medical director/health authority.
Travelers can protect themselves further by doing the following:
Pregnant women and women planning to get pregnant should consider postponing travel to areas where Zika virus transmission is ongoing, and talk to their doctor or other healthcare provider first and strictly follow steps to avoid mosquito bites during the trip.
