Just three days after two positive mosquito samples were confirmed in Dallas County, another mosquito has returned positive for West Nile virus according to the Dallas County Health and Human Services Department.
The latest positive test comes from ZIP 75149 code in Mesquite. Earlier this week, two samples were confirmed in Richardson and Highland Park in 75080 and 75205 postal codes. Last month, the first mosquito test positive for West Nile in Dallas County was also in the postcode 75080.
The county has not announced any plans to spray mosquitoes.
West Nile Virus is a disease spread by bites of an infected mosquito.
Mosquitoes can become infected when feeding the blood from infected birds. The infected mosquitoes can then transfer WNV to humans and animals. Serious WNV infections can cause neurological complications such as encephalitis. Milder symptoms include fever, headache and muscle pain. There is no vaccine or specific treatment for WNV.
"Mosquito season is here. We want the Dallas County residents to know to expect more positive traps this season and therefore remember the 4 Ds." said Dr. Philip Huang, DCHHS Director, in a previous statement.
