Make West Nile Virus Prevention A Part of Your 4th
of July Plans
(Santa Ana) – Independence Day is a time for family gatherings, picnics in
the park and fireworks displays. But the arrival of West Nile Virus in
California this year means a few extra precautions are needed to protect
your family and yourself from the possibility of West Nile Virus infection.
“Reducing your risk of West Nile Virus (WNV) infection is easy,” said Dr.
Mark Horton, County Health Officer. “Just as we urge people to be careful
when using fireworks, this holiday weekend we want everyone to protect
themselves from mosquito bites to reduce their chance of WNV infection.”
There have been no confirmed human cases of WNV infection in Orange County
this year. However, human cases have been reported in several neighboring
counties, including San Bernardino, Los Angeles and Riverside. WNV has also
been confirmed in numerous dead birds and mosquito pools in Orange County.
Recommendations to deter mosquitoes include using insect repellent
containing DEET, always following label directions. Since dusk is one of the
times that mosquitoes are most active, those attending fireworks displays
should plan on wearing appropriate clothing. If possible, wear long-sleeves,
long pants and socks. Light colored clothing can also help you to see any
mosquitoes that might land on you. Mosquitoes may bite through thin
clothing, so spraying clothes with insect repellent will give extra
protection. Don’t spray insect repellent containing DEET on the skin under
your clothing. Since insect repellents should not be used on infants younger
than two months, parents should place mosquito netting over infant carriers
when outdoors.
Individuals with pre-existing health conditions that might weaken their
immune system should consider reducing their exposure to mosquito bites by
limiting their time outdoors. Around your home, recommended WNV prevention
measures include eliminating any standing water from your property to reduce
mosquito breeding and making sure your window and door screens are in good
condition to keep mosquitoes outside.
Most people who become infected with WNV do not experience symptoms or
become ill, but about 20% of those with WNV infection may have fever,
headache, body aches, rash, or other mild to moderate symptoms. About one
out of every 150 people infected with WNV may develop a more severe form of
the illness and adults over 50 years of age are at increased risk of serious
complications from WNV infection. Anyone who develops symptoms such as high
fever, confusion, muscle weakness, severe headaches or stiff neck should
seek medical care immediately.
