West Nile Virus

Because the WBFI believes it is important to promote responsible feeding, and because many birding customers are concerned about birds and mosquitoes carrying the West Nile Virus, WBFI presents the following links to help you get the information you need to respond to questions and concerns.

We urge you to remember this:

* Birds to not transmit the West Nile Virus.

* Mosquitoes transmit the West Nile Virus.

Current information on the progression of West Nile Virus in North America is available from several sources. To visit these websites, please click on the links below.

Cornell University, Environmental Risk Analysis Program (ERAP)
The ERAP site is a resource for readers on WNV-related information such as the transmission cycle. ERAP provides maps detailing the spread of WNV through 2002. For maps beginning in 2003 up to the present, please follow the CDC links below.

Fight the Bite!
Centers for Disease Control and Prevention (CDC)
This is the link to the CDC homepage for West Nile Virus information. From this link, the reader may move to numerous topics on not only the CDC site, but other sites as well.

For a quick visual look at the number of human and other infections in 2004, this is the link to the CDC site showing the map for 2004. WNV maps are updated regularly to reflect surveillance reports released by state and local health departments to the CDC Arbonet system for public distribution.

For a quick visual look at the number of human infections in 2003, this is the link to the CDC site. The map is current as of the end of 2003. CDC reports the distribution of avian, animal, or mosquito infection occurring during 2003 with number of human cases, if any, by state. If West Nile virus infection is reported to CDC Arbonet in any area of a state, that entire state is shaded accordingly.

Curious to know what bird species have confirmed avian mortalities? Click on the above link to go to the CDC's list, which started in 1999 and runs through the present.

CDC has maintained the Arbovirus Diseases Branch for many years. The monitoring of West Nile Virus falls within this branch of the CDC. Follow the link above to go to information on the mission of and sections within the Arbonet.

U. S. Geological Survey (USGS)
If you need maps showing data at a county level for US states, this is the link to use. You will find data reported for birds, humans, mosquitoes, sentinels, and veterinary. Background information and historical data are also available through this site.

Health Canada link given here will take you to their West Nile Virus Surveillance area. From this link, you will access information on dead birds submitted for testing, and the results of those tests. This site is updated regularly.

Health Canada provides links to provinces and territories, which post information on West Nile Virus results for humans, birds, mosquitoes, and horses.

Mexico information is available in Spanish at this link. The maps show Mexico as well as the US.
