Zika - What You Need to Know
The City of Grapevine is working with Tarrant County Public Health in responding to imported cases of the Zika virus. As of late June 2016, there have been no cases of locally transmitted (via mosquito) Zika cases in the U.S. There have been numerous imported (illness acquired outside of the U.S.) cases of Zika in North Texas, however.
In an effort to prevent the potential localized transmission of the Zika virus in Grapevine. The City, in conjunction with Tarrant County, has increased monitoring of populations of Aedes mosquitoes, the Genus of mosquito that is known to transmit the Zika virus in other countries. This mosquito has different habits than those that carry WNV in that they actively hunt in the daytime (not just dusk and dawn) and they primarily feed on humans (Culex mosquitoes primarily feed on birds). Aedes mosquitoes are weaker flyers than Culex mosquitoes, so they tend to hang around where people are, not straying too far away.
Additionally, residents can help protect themselves by following a modified version of the WNV protection Four D's (see below), including:
- If you must be outside, where light color clothes and cover as much of your body as possible.
- Use a bug repellent containing DEET at all hours of the day, not just dusk and dawn.
The City of Grapevine has provided an Anti-Mosquito Yard Inspection form HERE for your use.
