CDC: West Nile virus on the rise

by Carol Thompson

As another infected pool of mosquitoes was found in Oswego County, U.S. officials have announced that West Nile virus is on the increase, having been found in 47 states.

A total of 1,118 cases of West Nile virus disease in people, including 41 deaths, have been reported to the U.S. Center for Disease Control and Prevention.

Of these, 629 (56 percent) were classified as neuroinvasive disease (such as meningitis or encephalitis) and 489 (44 percent) were classified as non-neuroinvasive disease, according to the CDC.

The 1,118 cases reported thus far in 2012 is the highest number of West Nile virus disease cases reported to the CDC through the third week in August since West Nile virus was first detected in the United States in 1999.

Recently, in Onondaga County, an adult fell victim to the disease and in the City of Oswego, a child is reportedly recovering from the virus.

County does not plan to spray for West Nile at this time

by Carol Thompson

Oswego County officials have decided to hold off aerial spraying for mosquitoes infected with the West Nile virus.

The Town of Hastings board,  however, is the process of conducting its own aerial spraying.

Legislator Amy Tresidder has asked at the two most recent meetings of the legislature if spraying would take place. The answer was no each time.

Friday, Majority Leader Jack Proud issued a memo to legislators explaining the decision.

“In light of the Town of Hastings decision to spray for mosquitoes on their own, as chairman of the Health Committee, I want to bring you up to date on the status of the county’s mosquito control efforts,” Proud wrote. “First, the town board made its decision to spray based on local events and requests regarding West Nile Virus. As you know, Eastern Equine Encephalitis has not been detected in Oswego County yet this year.”

The memo continues, “Due to the unusually dry weather this year, mosquito populations in the county are very low, significantly reducing the risk to humans of infection. Onondaga and Oswego counties have held off on spraying so far this year.”

To date, mosquito samples taken from the New Haven and Central Square areas have tested positive for West Nile virus, however, as of press time, there has been no trace of EEE.

West Nile on the rise in the U.S.

by Carol Thompson

West Nile virus has been making a strong comeback throughout the United States, despite the drought and the low mosquito population.

In a statement released by the U.S. Center for Disease Control and Prevention, it is noted that higher than usual rates of West Nile virus infections have been reported.

“Though West Nile infections tend to occur every summer, this year’s outbreaks have thus far been earlier and more significant than in previous years,” the press release states. “Most infections occur from June into September and the highest infection numbers are usually in mid-August. The number of reported West Nile Viruses at the end of July, however, has not been this high since 2004.”

Locally, infected mosquitoes have been found in New Haven and Central Square.

In Onondaga County, the virus has reportedly become widespread.  Neither Oswego or Onondaga counties have plans to aerial spray at this time.

This year, there have been of 241 cases of West Nile virus reported nationwide, including four deaths.

“It is not clear why we are seeing more activity than in recent years,” said Marc Fischer, a medical epidemiologist in the CDC’s Arboviral Diseases Branch, in a statement. “Regardless of the reasons for the increase, people should be aware of the West Nile virus activity in their area and take action to protect themselves and their family.”

While most cases of West Nile virus have been reported in Texas, Mississippi and Oklahime, 42 states have reported infections in humans, birds or mosquitos. The virus is most often transmitted to humans by mosquitos.
