It is not uncommon for West Nile to be detected in local mosquito pools. Last year, Louisiana recorded 617 positive mosquito pools, including four in New Orleans, and three people died of the virus last year, according to the Louisiana Department of Public Health.

New Orleans reports increased West Nile virus activity; mosquito control efforts, including aerial and ground spraying, are underway in affected areas. No human cases reported yet; precautions advised.

The city of New Orleans has detected West Nile virus in mosquito populations across multiple neighborhoods, prompting an increase in spraying and public health outreach as mosquito season hits its peak.
