Mosquito Alert: West Nile Virus Found in Las Vegas
29 Jun
Summary
- West Nile-positive mosquitoes found in three Las Vegas ZIP codes.
- Health officials urge residents to eliminate standing water.
- Most West Nile infections cause no symptoms, but some can be severe.

Health officials in Las Vegas are alerting residents to the presence of West Nile virus, with positive mosquito findings in three local ZIP codes. Routine surveillance identified the virus in ZIP codes 89121, 89169, and 89139, prompting a call for increased community vigilance.
Preventative measures focus on eliminating potential mosquito breeding grounds. Residents are advised to meticulously check yards, pools, and patios for standing water. Common culprits include neglected pool covers, plant saucers, pet bowls, clogged gutters, birdbaths, and even 'green pools' left untreated.
The Southern Nevada Health District commenced its surveillance program in March, earlier than usual, due to favorable weather conditions. They will continue monitoring mosquito activity in affected areas. While most West Nile virus infections show no symptoms, a small percentage can lead to fever, headache, body aches, and in rare cases, serious neurological illness.
