Maryland Reports First Human West Nile Virus Case of the Year

The Maryland Department of Health has announced the first confirmed human case of West Nile virus in the state for this year. The case involves an adult residing in the central region of Maryland, and officials have reported that the individual is currently recovering from the illness. While the exact location within the central area has not been specified, health authorities emphasize the importance of awareness during this season.

West Nile virus transmission occurs primarily through mosquito bites, with the infected mosquito having contracted the virus from feeding on infected birds. Many individuals infected with the virus remain asymptomatic, but it can lead to severe health complications, especially in those with pre-existing conditions.

Dr. Meg Sullivan, Maryland's Deputy Secretary for Public Health Services, highlighted that this is the period of heightened risk for mosquito-borne illnesses in the state. She advised residents to be cautious and adopt preventive measures such as eliminating standing water, which serves as breeding grounds for mosquitoes.

In 2024, Maryland recorded 18 confirmed cases of West Nile virus, with the numbers fluctuating annually according to health officials. The virus was first identified in the U.S. in 1999.

Common symptoms of the infection include fever, headache, body aches, swollen lymph nodes, and skin rashes. While most recover within days, symptoms can persist for weeks in some cases. Elderly individuals and those with weakened immune systems are at increased risk for severe neurological illness.

Preventive actions recommended by health authorities include wearing protective clothing outdoors, using EPA-registered insect repellents, and regularly checking properties for stagnant water sources like clogged gutters or containers that could attract mosquitoes.

The Maryland Department of Health initiated a public awareness campaign earlier this year to promote mosquito bite prevention, sharing tips via social media. Additionally, residents are encouraged to report sick or dead birds, which may carry the virus, to wildlife authorities at 1-877-463-6497 or through the Maryland Department of Natural Resources website.

Protecting oneself during peak mosquito activity remains critical to prevent West Nile virus infection and its potential health consequences.
