Human West Nile virus case confirmed in Oklahoma County

Monday, 09 Jul, 2018

"Culex pipiens mosquitoes, which are the primary carriers of West Nile virus, are most abundant in mid- to late summer, when the weather is hot", said Michael Adam, Senior Biologist for the Health Department. No Massachusetts residents have tested positive for West Nile virus this year. An effective repellent will contain DEET, picaridin or oil of lemon eucalyptus.

Wear long, loose and light-colored clothing. According to the Centers for Disease Control and Prevention (CDC), as of the end of June, 23 states have reported cases of West Nile virus in mosquitoes, people, and birds in 2018.

"I'm not sure that it's related to Harvey at this time but I can tell you that the additional moisture that we received just yesterday is certainly gonna create more of a breeding ground for these mosquitoes, so it's gonna be real important that we stay on top of it", Noack said. The program also monitors reports of dead birds (an early sign of the presence of the virus) and investigates areas of stagnant water for the presence of mosquito larvae, specifically from the Culex mosquito, which is the primary carrier of West Nile in IL. Since 2002, there have been 64 confirmed human cases of West Nile virus in Lake County, as well as two confirmed deaths.

A human can be transmitted West Nile from the bite of a mosquito infected with the virus. Not everyone infected with West Nile Virus will become ill. People over the age of 50 are at the greatest risk of serious illness, such as encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord).

A little over three weeks after a consortium of public health officials gathered in the Texas Rio Grande Valley to discuss strategies for controlling mosquito-borne diseases, like Zika virus and West Nile Virus, rain-soaked South Texas is now experiencing a full-fledge explosion of mosquito populations, spawning quick action by city and county governments to step up vector control efforts to slow and hopefully control the invasion.
