Maryland reports 1st human case of West Nile virus this year

August 3, 2026 - 02:08

State health officials have announced the first human case of West Nile virus in Maryland for this year. The Maryland Department of Health confirmed the infection on Tuesday, though they did not release details about the patient's identity, age, or exact county of residence, citing privacy concerns.

West Nile virus is typically spread through the bite of an infected mosquito. Most people who contract the virus show no symptoms at all, but about one in five will develop fever, headache, body aches, joint pain, vomiting, or a skin rash. In rare cases, especially among older adults or those with weakened immune systems, the virus can cause severe neurological illness such as encephalitis or meningitis.

Health officials are urging residents to take precautions as mosquito activity remains high during the late summer and early fall. They recommend using EPA-registered insect repellent, wearing long sleeves and pants during dawn and dusk when mosquitoes are most active, and removing standing water around homes where mosquitoes breed. This includes checking gutters, flower pots, birdbaths, and old tires.

The confirmation comes amid heightened concern over mosquito-borne diseases in the region. While West Nile virus is not new to Maryland, the timing of this first case serves as a reminder that transmission season is far from over. Last year, the state reported a handful of human cases, with no fatalities. Officials say they will continue monitoring mosquito populations and testing birds for the virus to track its spread. Anyone experiencing severe symptoms after a mosquito bite should contact their healthcare provider promptly.
