HARRISBURG, Pa. -- Pennsylvania Environmental Protection Secretary Kathleen A. McGinty today proposed $5.2 million in grants to help Pennsylvania counties finance their West Nile Virus Control Programs in 2005 and keep residents healthy and safe.
"Working with our county partners, DEP is prepared once again to launch an
aggressive mosquito monitoring and control program to contain West Nile virus
in Pennsylvania," McGinty said. "This funding will help counties
and their established surveillance programs wage a successful suppression
effort against the virus-carrying mosquitoes through the fall."
The funding proposals were developed through consultations between DEP
West Nile Virus Control Program staff and county officials. Counties will
begin receiving a portion of their funding from current fiscal year
appropriations to begin 2005 operations. The remainder of the funds cannot be
distributed until the new fiscal year begins July 1. The actual final amounts
depend on passage of the Governor's proposed 2005-06 budget.
Total proposed funding is below the $6.4 million awarded in 2004, largely
because counties already have purchased their needed equipment, such as
mosquito traps, to operate their programs, so major capital expenses are not
needed this year.
In addition, the department has learned a great deal from its four years
of running the West Nile Virus Control Program. These years of experience
mean targeting resources more efficiently and ensuring an even greater
effectiveness of field programs. County staff members have become extremely
effective in locating areas that dictate control activity.
"In the early part of the season, our field staff and county partners will
be targeting a specific species, Culex restuans, which we believe played a
significant role in spreading the virus among birds early in the 2003 season,"
McGinty said. "Culex restuans rarely bite people, but by spreading
the virus more widely through the bird population, it helps to spread it to
other mosquito species that do bite people. We believe targeting a particular
species contributed to the lower incidence of West Nile virus in Pennsylvania
during the 2004 mosquito season."
In 2003, 247 people in Pennsylvania were confirmed with West Nile virus,
and eight died. Last year, 15 people were confirmed with West Nile Virus, and
two died. Nationally in 2003, the virus infected more than 10,000 people and
resulted in 264 deaths. In 2004, 2,449 people contracted the disease with 81
fatalities reported nationwide.
McGinty noted that most people bitten by an infected mosquito
will never develop any symptoms, and one in 150 who do develop symptoms will
contract the more serious West Nile encephalitis, a swelling of the brain that
can cause serious health problems that may be fatal. Health and environmental
officials recommend people turn over containers to get rid of standing water,
which serves as mosquito breeding areas on their properties, and use insect
repellant containing DEET when outdoors in warm weather.
DEP and county staff use environmentally sensitive materials to control
the mosquito population. For killing larvae, which is the major method of
mosquito control, Bti and Bsph, naturally occurring bacteria, are used. These
bacteria attack the digestive system of the mosquito larvae and have no effect
on people, animals, plants or other insects. The other larval control product
is an insect hormone, methoprene that prevents the mosquito larvae from
developing into adults. The products used to kill adult mosquitoes are
selected based on their environmental sensitivity and are applied in a way to
protect people, animals and plants.

Robust infectious disease surveillance, including rapid subtyping of influenza A, is essential for early detection, containment, and public health reporting of novel viral threats.
