Dallas County health officials reported three additional human West Nile virus (WNV) cases Friday, all in residents of the city of Dallas, bringing the county total to 15 for 2020.
The death count in the county is four.
WNV is usually transmitted to humans through the bite of an infected mosquito.
West Nile virus symptoms usually develop between two and 14 days after a person is bitten by an infected mosquito. Symptoms may include fever, headache, nausea, vomiting, body aches, skin rash and swollen lymph glands. Older individuals or individuals with compromised immune systems are at higher risk of severe illness.
