The Maryland Department of Health has confirmed the state’s first human case of West Nile virus this year and is urging residents to take precautions to protect themselves from mosquito bites.
According to the department, the individual lives in Maryland’s Capital Region. No additional information about the patient has been released to protect their privacy.
West Nile virus is spread primarily through the bite of an infected mosquito that has fed on infected birds. Health officials said up to 80% of infected people do not develop symptoms, but some may experience fever, headache, body aches, swollen lymph nodes or a skin rash. Adults over age 50 and people with weakened immune systems are at greater risk of developing severe illness.
The Maryland Department of Health recommends using EPA-registered insect repellent, wearing clothing that covers exposed skin and eliminating standing water around homes where mosquitoes can breed. Officials also advise residents to use extra caution during mosquito season, as even small amounts of standing water can produce dozens of mosquitoes.
In 2025, Maryland reported 23 confirmed human cases of West Nile virus. Health officials said the number of infections varies from year to year and encouraged residents to take preventive measures throughout the summer.
