The mosquito pool tested positive for West Nile Virus, a disease that can cause encephalitis and meningitis in some cases, according to York County spokeswoman Gail Whittaker. Symptoms include headache, body aches, joint pains and fatigue.
Seven human cases of the mosquito-borne illness have been discovered in NY state so far this year, with three recent cases in Nassau, Westchester and Monroe counties.
A new map out this week puts almost all of Kansas in high risk for West Nile Virus.
Birds and horses can also contract the virus.
West Nile virus is spread to humans by mosquitoes that were infected by biting a diseased bird.
According to the health unit, about 80 per cent of people who become infected won't show symptoms. In rare cases, more severe illness can occur.
To prevent catching West Nile, you should take measures to avoid being bitten by mosquitoes.
"While we have been enjoying the cool weather, temperatures are expected to climb back up next week and this means that that there is still a possibility of becoming sick with West Nile". This mosquito type is primarily active during daytime hours unlike the previously reported mosquito type, which was active during dusk and dawn. "We express this a lot when we do our education program, around your home if you have any standing water, like in buckets or tires, or even kids toys out in the yard, anything that holds water, just make sure you take a little bit of time and dump the water. But then I said, well with all the rain and everything anything's possible with the mosquitos that have been out and about as much as they have been". This brings the statewide total to 30 cases. As of Friday, 31 human cases have been confirmed and this number is expected to grow throughout the next few weeks.
