Denton County health officials confirmed Wednesday the county's first case of Zika virus.
The patient, whose name and personal information are not being disclosed, is a female who traveled internationally in January to a country where the virus is active, according to Denton County Public Health.
So far, there are no confirmed reports of Zika transmission by mosquitoes in the United States.
Common symptoms of Zika virus include fever, rash, joint pain and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting several days to a week, Dallas County health officials said.
The latest news from around North Texas.
There is no medication to treat Zika virus and there is no vaccine; the best prevention is to avoid mosquitoes and sexual contact with infected people. The recommendations for avoiding the Zika virus are the same for avoiding West Nile virus.
- Dress in long sleeves, pants when outside: For extra protection, spray thin clothing with repellent.
- DEET: Make sure this ingredient is in your insect repellent.
- Drain standing water in your yard and neighborhood: Mosquitoes can develop in any water stagnant for more than three days.
It has been recommended in the past that to avoid mosquito bites you should avoid being outdoors during Dusk and Dawn (the 4 Ds). While this is true for mosquitoes that commonly carry the West Nile virus, other types of mosquitoes that are more likely to carry Zika, dengue and chikungunya are active during the day. When outdoors, no matter what time of day, adjust your dress accordingly and wear insect repellent containing DEET, picaridin or oil of lemon eucalyptus as your first line of defense against insect bites.
