State's first West Nile found in Gaithersburg

Mosquitoes collected by county health department officials over several days last month are the first in the state to be identified as carrying the virus, according to the state Department of Agriculture.

The mosquitoes were collected as part of a statewide monitoring program. It could not immediately be learned where the mosquitoes were found in Gaithersburg.

"We know that West Nile virus may be present throughout Maryland and are not surprised to find mosquitoes testing positive," said Secretary of Agriculture Roger Richardson in a prepared statement. Detection of the virus serves as a "reminder" to residents to protect themselves from insect bites and control mosquito growth in their yards.

Less than 1 percent of people bitten by a mosquito carrying West Nile virus will become ill, health authorities said.

Most at risk are those with compromised immune systems and those over 50. Preventive measures include avoiding unnecessary outdoor activities at dawn and dusk, and wearing insect repellents, long sleeves and pants.

Repairing holes in screens, removing standing water from flower pots and other containers and flushing pets' water bowls and bird baths will also cut down on mosquito population growth.
