West Nile Virus in Dead Birds - 2016
2016 West Nile Virus in Birds and Humans - Epidemiology Reportpdf icon3.1

Why test dead birds for West Nile Virus?
Tracking West Nile Virus (WNV) WNV in dead birds reveals places and months in which the virus is most active.

What do the results tell us about
WNV this year?

In 2016, total of 188 dead birds have been tested for WNV in LA County in 2016. Of these, 124 birds (66%) were positive for the virus.

As was expected, the number of birds was highest in August. Most WNV - positive birds have been in the western half of LA County (see map).

How do I report a dead bird?

Where does this data come from?

Members of the public report dead birds and to various agencies in LA County and in California. Each dead bird is tracked, even when they cannot be tested for WNV.  The Veterinary Public Health Program graphs and maps the LA County data from all participating agencies and shares it on this page.

The dead bird testing effort has been in operation since 2004, the year after the virus first appeared in LA County. It has helped reveal shifts in the environmental epidemiology of the virus over the years. Testing was significantly decreased in mid-2013, and began to increase again in 2015. A vibrant dead bird testing program is an essential part of tracking the virus in our environment in LA County.
