MOUNT VERNON — Summer has arrived
and so has mosquito season. As families and friends take to outdoor fun, the
Knox County Health Department cautions residents to use bug and mosquito repellent,
as well as wear long-sleeve clothing during peak mosquito hours, to protect against
bites.
Several diseases can be borne from mosquitos in Ohio, including West Nile Virus.
“West Nile is an encephalitis viral infection,” said Terri Hillier
of the Knox County Health Department, Environmental Health Division. “It
can be very serious, and, like all diseases, it can be more serious for people
that are older, children or someone that is dealing with other types of health
issues. At this time we haven’t received any communication that in Ohio
we have a positive pool of mosquitos with West Nile.”
According to the Center for Disease Control and Prevention, most people infected
with WNV show no symptoms, but for the low percentage who do, symptoms may include
a fever, headache, body ache, nausea or vomiting. In a small number of severe
cases, people have been hospitalized.
The best way to avoid getting West Nile is to avoid mosquito bites, said Hillier.
“The public needs to take precautions if they are out early in the morning
or late in the evening, when mosquitoes activity is at its highest, to use some
type of approved bug spray that contains some Deet. Also, make sure window and
door screens are in place in their homes. The main thing is to make sure they
don’t have any standing water in flower pots, abandoned tires or any stagnant
ditches on their property, because that’s where the mosquito larvae hatch,” said
Hillier.
“It is necessary to report cases because we are starting our spraying schedule
and if we are aware where there might be increased mosquito activity that may
be related to the dead birds that are found in that area, we can spray,” said
Hillier.
This year the health department will not test birds for West Nile, but possible
cases of the virus are monitored closely. Hillier advises residents who find
dead birds, specifically crows and blue jays, to report them to the health department.
The health department will take information on the location of deceased birds
and inform residents on how to properly dispose of the remains.
“If we start to see more calls in a certain area, then we will know that
it could possibly be related to West Nile,” she said.
Any mammal can get the virus, but the virus is carried by the bird. If the bird
is bitten by a mosquito, the mosquito can then infect humans and other animals.
“West Nile became a hot topic in 1999. In 2002, that was the most active
year, and there were quite a few deaths including in Ohio. In 2009, there were
only two reported confirmed West Nile diseases in the state of Ohio, so there
was very low activity last year,” said Hillier.
For more information call the health department at 392-2200 and ask for the environmental
divison. If it is after hours, Hillier said residents may call to leave a message
or e-mail her at thillier@knoxhealth.com to report an incident of dead birds
or possible infection.
“If the animal is a dog, cat or horse, the person should contact their
veterinarian,” said Hillier, adding that if a person suspects West Nile,
the veterinarian can take blood work for testing the cause of death. If the animal
was infected with WNV, the health department will be notified.
