Residents in Norristown are now in danger of getting infected with the West Nile virus brought by the mosquitoes in the area. The virus is really brought by some birds but after these birds die, the mosquitoes collect their blood and then infect the people.

The Montgomery County health department issued on Friday a report asking the residents in the area to dispose on any containers that collect water on their property as the officials will lead a street-to-street spraying of pesticide in the neighborhoods from Norristown.

The spraying will take place on Monday if the weather conditions will permit it and it will be exactly like to one preceded earlier this month. For the spraying the officials will use four tracks identified as Pennsylvania Department of Environmental Protection (PADEP) vehicles.

The pesticide will be Biomist 3 plus 15 and it will be used in amounts like 0.75 ounces an acre. Health departments consider it to be harmless for people and pets. Still, they suggested some precautions like to remain inside when the spraying takes places.

Officials also advised the residents to close their windows and doors and not let children play near or behind the trucks while they are spraying. Also pets will have to be indoors and fishponds will have to be covered.

The Norristown County has been the focal point of West Nile virus development and prevention efforts from the health departments. This county has registered more than 425 sample groups of mosquitoes in its laboratories.

The first Wile Nile Virus since 2003was reported on July 22 on a 27-year-old woman. After she was in a coma she was released and recovering.
