First report of West Nile Virus found in Massac County

(WSIL) — Southern Seven Health Department has confirmed the first mosquitoes to test positive for West Nile Virus from the lower seven counties of the state in 2019.  S7HD staff collected the positive mosquitoes in Massac County in early July.  No human cases of West Nile virus have been reported so far.

In a press release Wednesday, S7HD said the recent rains and flooding in this part of the state are leaving pools of water behind, which encourage mosquito harboring.  

“As we start to see higher temperatures, we will start to see more West Nile virus activity,” said Acting IDPH Director Dr. Ngozi Ezike, “While we see West Nile virus in Illinois ever year, it is important not to become complacent.  It’s easy to take precautions to protect yourself by wearing insect repellent and getting rid of standing water around your home.” 

West Nile virus is transmitted through the bite of a Culex pipiens mosquito, commonly called a house mosquito, that has picked up the virus by feeding on an infected bird. Common symptoms include fever, nausea, headache and muscle aches.

Symptoms may last from a few days to a few weeks. However, four out of five people infected with West Nile virus will not show any symptoms. In rare cases, severe illness including meningitis, encephalitis, or even death, can occur.

Precautions to Fight the Bite include practicing the three “R’s” – reduce, repel, and report. 
• REDUCE – make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut. 

Eliminate, or refresh each week, all sources of standing water where mosquitoes can breed, including water in bird baths, ponds, flowerpots, wading pools, old tires, and any other containers. 

• REPEL – when outdoors, wear shoes and socks, long pants and a light-colored, long-sleeved shirt, and apply insect repellent that contains DEET, picaridin, oil of lemon eucalyptus, or IR 3535 according to label instructions. Consult a physician before using repellents on infants. 

• REPORT – report locations where you see water sitting stagnant for more than a week such as roadside ditches, flooded yards, and similar locations that may produce mosquitoes. The local health department or city government may be able to add larvicide to the water, which will kill any mosquito eggs.
