September 19, 2003 - To date, there are no HUMAN WNV "postives" in Lycoming County this year. Throughout Pennsylvania, however, there have been 80 human positives in 28 counties. Last year there were 62 human positives in 17 counties to this date. The 80 statewide human positives range in ages from 7 - 81 years old. There are 43 female and 37 male positives with an average age of 45 years. In Lycoming County, we continue to conduct larviciding and adulticiding based on the finding of positive mosquitoes as well a high concentration of mosquitoes in various areas. This has now become much more important than previous years due to the continued rains which produce more wetland areas. Freezing temperatures will be needed to reduce the mosquito production.

 
September 15, 2003 - Today, the Department of Health reported that new WNV "positive" mosquito pools have been found in Mifflin Township, Old Lycoming Township, Porter Township and Mifflin Township, Lycoming County.

 
September 10, 2003 - Today, the Pa. Department of Health announced that 1 horse in Lycoming County has tested "positive" for West Nile Virus.
 
September 9, 2003 - DEP has reported that today another American Crow found in Old Lycoming Township has tested "positive" for West Nile Virus. This brings a total of 7 of the 10 crows tested in the County have tested positive. From the 219 mosquito samples collected, only 5 have tested positive. From the 203 Sentinel Samples tested, none have been positive. There have been no human cases reported in the County.
 
September 8, 2003 - Due to the high number of adult mosquitoes known to carry West Nile Virus, DEP's West Nile Virus Control Program will be conducting adult mosquito treatments to reduce the number of adult mosquitoes in the City of Williamsport, Lycoming County. DEP and Lycoming County West Nile Virus staff will be assisting Clarke Environmental Mosquito Management, Inc. with the mosquito adulticiding operations. The adulticiding operations, scheduled for Monday, September 8,will consist of a barrier spray with Flit 10EC and an ultra-low volume (ULV) application of Anvil 10 + 10.

The Flit 10EC and Anvil 10 + 10 will be dispersed from backpack and hand-held spray units. Anvil 10+10 will also be dispersed from a truck mounted unit. These treatments will begin in the evening, when adult mosquitoes are active, and conclude shortly after dark.

Weather conditions, lowered adult mosquito populations and other unforeseen situations could cause the spray operations to be delayed or cancelled. If you have any questions, please contact Eric Mosbacher at 570-327-3783 or 570-971-1351 (cell).

 
August 12, 2003 - The Department of Environmental  Protection announced today that there has been a mosquito pool found to be "Positive" for West Nile Virus in Montgomery Borough. Further discussion and planning will be done with DEP concerning treatment of the area where the positive sample was located.

July 28, 2003 - HEALTH SECRETARY SAYS TESTS SHOW FIRST HUMAN CASEOF WEST NILE VIRUS THIS YEAR IN PENNSYLVANIA

Patient recovered; Pennsylvanians reminded to
take action to prevent mosquito-breeding sites.

 HARRISBURG: Health Secretary Dr. Calvin Johnson today reported the first human case of West Nile virus in Pennsylvania this year.  The individual, a 46-year-old Philadelphia woman, has fully recovered from the illness.

“The fact we have seen the first human infection from West Nile reminds all of us that we should take precautions to help reduce the risk of illness,” Secretary Johnson said. “The case is not unexpected, since we’ve known for several months -- through bird, mosquito and animal testing -- that West Nile virus is present in Pennsylvania.”

Secretary Johnson urged Pennsylvanians to keep proper perspective on the health risks of West Nile.

“The chance of contracting West Nile virus from an infected mosquito is small,” Secretary Johnson said.  “Even if you’re bitten by an infected mosquito, your chances of becoming seriously ill are even smaller.  However, it is important to keep in mind that all Pennsylvanians -- particularly older adults and people with compromised immune systems -- should take simple precautions to reduce their risk.”

Secretary Johnson recommends these simple precautions to prevent mosquito bites, particularly for those most at risk:

  • Make sure screens fit tightly over doors and windows to keep mosquitoes out of your home;
  • 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;
  • When possible, reduce outdoor exposure at dawn and dusk during peak mosquito periods (usually April through October); and
  • Use insect repellents according to the manufacturer’s instructions.  An effective repellent will contain DEET.  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.
Pennsylvanians also can reduce the risk of West Nile virus by eliminating the places where mosquitoes breed.  Mosquitoes can breed in any puddle that lasts more than four days.
  
 “I strongly urge all Pennsylvanians to take just a few minutes to walk around their homes and get rid of stagnant water that may have collected on their properties,” Secretary of Environmental Protection Kathleen McGinty said.  She suggests some simple steps that can be taken around the house:
  • Eliminate standing water in any type of containers, including tin cans, plastic containers, bird baths or ceramic pots;
  • Remove standing water from discarded tires;
  • Clean clogged roof gutters and drains, especially if leaves from surrounding trees tend to plug up drains;
  • Clean and chlorinate swimming pools;
  • Turn over plastic wading pools and wheelbarrows when not in use;
  • Aerate ornamental pools or stock them with fish; and
  • Drill holes in the bottom of recycling containers left outdoors.

West Nile virus is spread to people and animals by infected mosquitoes.  The virus can cause West Nile encephalitis, an inflammation of the brain.  While anyone can contract the virus, older adults and people with compromised immune systems are at highest risk of developing the disease.

People with mild infections of West Nile virus may experience fever, headache, body aches, skin rash and swollen lymph glands.  People with more serious infections may experience high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, occasional convulsions and paralysis.  Secretary Johnson advises anyone with any of these symptoms to contact a doctor. There is no specific treatment for West Nile virus.  While most people fully recover, in severe cases, hospitalization is needed.

"West Nile Virus also poses a significant threat to unvaccinated horses," said Agriculture Secretary Dennis C Wolff.  "It is important for all citizens--particularly horse owners and farmers -- to be aware of the risk factors and take measures to protect both themselves and their animals from the virus."

So far this year in Pennsylvania, West Nile virus has been found in seven birds, 30 mosquito samples and one veterinary sample. The virus has been detected in 23 of Pennsylvania’s 67 counties. Pennsylvanians should presume that West Nile virus is present throughout the state and should take appropriate precautions.

Since January 1, there have been 16 identified human cases of West Nile virus in nine states across the country.
