McHenry
County Department of Health (MCDH) reports a significant increase in mosquitoes
testing positive for West Nile virus (WNV). Fifteen mosquito batches from
August 27-September 5 tested positive as compared to five positive batches over
a four month period (May-July). The recent trap locations were from Algonquin
Township, Harvard, Hebron, Lake in the Hills, Nunda Township and Spring
Grove. The recent dry hot weather is the perfect breeding environment for
the Culex mosquito which carries WNV. Residents are urged to take
precautions to reduce their risk of becoming infected with WNV.
As of
today, MCDH has tested 426 mosquito batches, with 20 testing positive.
The State Health Department reported 55 counties with WNV activity on September
4, with three human cases. McHenry County reported its first human case
of WNV for 2013 on August 21; six human cases of WNV were reported in McHenry
County in 2012. MCDH has submitted 21 birds this year for testing, with
nine testing positive for WNV.
It is
important to remember that the risk of WNV remains until the first hard frost.
MCDH will continue to collect and test mosquito batches throughout the
remainder of the season (mid-October). Residents should continue to use
insect repellent when going out of doors in the evening, with long sleeved
shirts and long pants for extra protection. Other tips include emptying
standing water from containers around the house and making sure doors and
windows have tight-fitting screens.
Illness
from West Nile virus is usually mild and includes fever, headache and body
aches but serious illnesses, such as encephalitis and meningitis and death, are
possible. Persons 50 and older have the highest risk of severe
disease. For more information on WNV, visit www.mcdh.info
