A Sutter County adult has been confirmed with the neuroinvasive form of West Nile Virus (WNV) illness and is recovering at home.
This is the first report of a case of WNV illness in Sutter County for 2017. In 2016, a total of 12 cases were reported with 1 death from WNV. There have been a total of five WNV-related deaths in Sutter County since WNV appeared in California, occurring in 2012, 2014 and 2016. The Sutter-Yuba Mosquito and Vector Control District continues to be active with mosquito control and monitoring mosquito activity and will continue until cold weather.
Risk for WNV infection from mosquito bites continues into late fall for humans, horses, and other mammals. It is very important to make sure to always take the simple precautions that reduce the risk of mosquito bites and becoming infected with West Nile virus whether at home, participating in outdoor activities, or traveling. The 4 “D”s is an easy way to remember how to prevent mosquito bites:
Most persons who become infected with WNV do not become ill, but develop immunity to WNV. Approximately one in five people who are infected with WNV will develop symptoms, such as fever, headaches, body aches, joint pain, vomiting, diarrhea or rash. Symptoms typically develop from 3 to 14 days after being bitten by an infected mosquito. Less than one percent of infected people will develop the neuroinvasive WNV infection which is a serious neurologic illness with encephalitis or meningitis (inflammation of the brain and surrounding tissues).
The State of California West Nile virus webpage has information about WNV activity around the state by county, how to report dead birds, and how to protect against WNV. Visit http://www.westnile.ca.gov.
