This week, the Mississippi State Department of Health confirmed the first human case of West Nile virus in Rankin County for the year. West Nile Virus Transmission: West Nile virus is primarily transmitted through the bite of an infected mosquito. While most people infected with West Nile do not show any symptoms, about 1 in 5 individuals may develop a fever accompanied by symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Summer and Mosquitoes: The summer months are considered prime time for mosquitoes to thrive and potentially spread diseases like West Nile virus. It is crucial to take precautionary measures to protect oneself from mosquito bites and minimize the risk of contracting the virus.
