McHenry County Reports first human case of West Nile Virus in 2015

McHenry County Department of Health (MCDH) has confirmed its first human case of West Nile Virus (WNV) of 2015, in person in their late 40’s from Algonquin. This individual is recovering at home after a brief hospitalization. As of September 25, the County has recorded eleven-mosquito batches positive for WNV and four birds have tested positive. In 2015, according to the Illinois Department of Public Health (IDPH), there have been 30 cases of human WNV with four deaths reported in the State.

MCDH continues to urge residents to take precautions as the risk of mosquito-borne WNV lasts until the first hard frost. Illness from West Nile Virus is usually mild and includes fever, headache and body aches, but serious illnesses, such as encephalitis, meningitis and death, are possible. Illness can occur 3-15 days after an infected mosquito bite. The disease can affect all ages, but persons 50 and older have the highest risk of severe disease.

The mot effective way to prevent against becoming infected with WNV is to follow some basic steps:

Limit your time outdoors during peak mosquito biting hours, which are from dusk to dawn.

When outside (evening and early morning), use repellent and protective clothing such as long-sleeves, long pants and socks.

Spray clothes with repellent containing DEET for extra protection. Always follow label directions.

Get rid of standing water around your home where mosquitoes will breed (bird baths, old tires, garbage cans, flower pot trays, wheelbarrows).

Have tight-fitting screens on both windows and doors; replace screens with tears.
