West Nile Virus Detected in Crows in San Diego, Early Warning Issued
US · Published Jun 5, 2026
San Diego County officials have confirmed the presence of West Nile virus in two dead crows, marking one of the earliest signs of the virus's activity in the region this year.
The birds were found in the Rolando area of East County and near Encanto and North Bay Terraces.

Why It's Important?

The detection of West Nile virus in crows highlights the potential risk of transmission to humans through mosquito bites. While most infected individuals experience mild symptoms such as fever, headaches, and fatigue, severe cases can lead to neurological complications or even death. Vulnerable populations, including the elderly and those with weakened immune systems, are at higher risk of severe outcomes. Additionally, mosquitoes in the region can carry other diseases like chikungunya, dengue, and Zika, further emphasizing the need for vigilance.
