West Nile Virus and Eastern Equine Encephalitis remain major concerns in Alabama

On Wednesday, July 31. 2025, the Alabama Department of Public Health cautioned the public about preventing mosquito bites in order to protect themselves from mosquito-borne diseases.

In Alabama, mosquito-borne diseases include Eastern equine encephalitis virus (EEEV) and West Nile virus (WNV) are a clear and present danger – especially in the summer months. WNV is the leading cause of mosquito-borne disease in the continental United States. Both WNV and EEEV can cause severe illness and death. No vaccine and no specific treatments are available for either condition. Therefore, the best defense against these diseases is to prevent mosquito bites in the first place.

To prevent mosquito bites ADPH urges all Alabamians to:

· Use insect repellents.

· Wear long sleeves, long pants, and loose-fitting, light-colored clothes when possible.

· Use air conditioning or screens on windows and doors.

· Since mosquitoes tend to lay eggs near standing water, empty and scrub, turn over, cover, or throw out any items that hold water.

· Stay indoors during dawn and dusk hours when mosquitoes are most active.

Additionally, mosquito-borne diseases such as dengue, Zika, chikungunya and malaria may be acquired during international travel. Transmission of these diseases occurs primarily in tropical and subtropical areas. This year, over 10 million cases of dengue have been reported in North, Central, and South America and the Caribbean. Local transmission of these diseases may occur when an infected traveler returns home and is bitten by a mosquito that picks up the virus or parasite and then transmits it to another person during its next blood meal.

· Look for lodging with screens or air conditioning or pack a mosquito net.

· If traveling abroad, find out if vaccines for mosquito-borne diseases are available.

· After your trip, watch for symptoms and prevent mosquito bites for three weeks.
