West Nile Virus Likes Hot, Dry Weather

The hot and dry weather are two factors promoting the virus and the mosquitoes’ development. 

“The hot weather decreases the time from egg to flying adult and also the virus replicates faster in this hot weather,” Zazra previously told Patch.  

In 2011, three human cases of West Nile Virus were found in Kenilworth, Glencoe and Northbrook, with one death, according to Zazra. The first human case occurred in Illinois in 2002, when the virus struck more than 800 individuals. It flared up again in 2005 and 2006, when the state recorded 252 cases and 12 deaths and 215 cases and 10 deaths, respectively.  

Virus Symptoms

According to the Centers For Disease Control and Prevention (CDC), roughly 80 percent of people infected by West Nile Virus do not show any symptoms. Milder symptoms, including fever, headache, body aches, nausea and vomiting, are common among the roughly 20 percent who do show symptoms.

While the vast majority of infected people show no symptoms, about one in 150 may develop severe symptoms. These can include high fever, disorientation, coma, muscle weakness, vision loss, numbness and paralysis, according to the CDC.

Adults older than 50 are more at risk of developing serious symptoms, and should be more cautious about avoiding mosquito bites.

Prevention Tips

When it comes to personal protection, health officials boil it down to two words: wear repellent. 

“Residents should start taking precautions by wearing repellent around dusk and dawn, and loose light color clothing,” Zazra said. “Basically cover as much skin as possible.”
