Health officials confirmed Maryland’s first case of West Nile Virus in Baltimore yesterday. The virus is usually transmitted to humans by mosquitoes that have been infected by birds. Eighty-percent of those who get the virus report no symptoms, however, those with underlying health conditions could suffer severe illness. Officials say disease surveillance teams are closely monitoring increasing numbers of infected mosquitoes in several areas across the state. More information about West Nile Virus can be found on the CDC website.
