HARRISBURG, PA (September 23,
2016) – The Dauphin County Conservation District has collected more West Nile
Virus-infected mosquito samples, bringing the total to 19 for the year. The most
recent infected samples were collected in Derry, South Hanover, Susquehanna, West
Hanover, Wiconiso townships and the City of Harrisburg. Other positive samples
were found in Londonderry and Williams townships.
The county’s WNV Control Program is continuing to monitor conditions
and increase control measures to reduce the mosquito population and prevent the
virus from spreading.
Certain species of mosquitoes carry WNV, which, when transmitted to
people, can cause West Nile encephalitis, an infection that can result in an
inflammation of the brain. According to the Centers for Disease Control and
Prevention (CDC), all residents of areas where virus activity has been
identified are at risk of getting West Nile encephalitis.
The following precautions are recommended:
Buy products with Bti (Bacillus thuringiensis
israelensis)--a naturally-occurring bacteria that kills mosquito larvae but is
safe for people, pets and plants--for stagnant pools of water in the lawn and
Remove any standing water in pots, containers,
pool covers, tires, wheelbarrows, wading pools, roof gutters and other
containers that hold water.
Make sure screens fit tightly over doors and
windows to keep mosquitoes out of homes.
Consider wearing long-sleeved shirts, long pants
and socks when outdoors, particularly when mosquitoes are most active at dawn
and dusk, or in areas known for having large numbers of mosquitoes.
Reduce outdoor exposure at dawn and dusk during
peak mosquito periods, usually April through October.
Use insect repellents according to the
manufacturer’s instructions. An effective repellent will contain DEET,
picaridin or oil of lemon eucalyptus. Consult with a pediatrician or family
physician if you have questions about the use of repellent on children, as
repellent is not recommended for children under the age of two months.
