Health authorities in DeKalb County have confirmed that mosquitoes collected from two separate traps have tested positive for the West Nile virus. The positive samples were identified during routine surveillance, prompting officials to urge residents to take precautions against mosquito bites.

The DeKalb County Board of Health announced the findings, noting that the infected mosquitoes were found in different parts of the county. While no human cases have been reported so far, the presence of the virus in the local mosquito population signals an increased risk of transmission.

West Nile virus is spread through the bite of an infected mosquito. Most people who contract the virus do not develop symptoms, but some may experience fever, headache, body aches, joint pain, vomiting, diarrhea, or rash. In rare cases, severe illness can affect the nervous system, leading to encephalitis or meningitis. Older adults and those with weakened immune systems are at higher risk for serious complications.

Health officials recommend using EPA-approved 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. Common breeding sites include bird baths, clogged gutters, flower pots, and old tires.

Residents are also advised to ensure window and door screens are intact to keep mosquitoes out. The county will continue monitoring mosquito activity and may conduct targeted spraying in affected areas.

Anyone who develops symptoms consistent with West Nile virus should contact a healthcare provider. The virus is not spread through casual contact like touching or coughing.
