Montgomery County Mosquitoes Test Positive Eliminate Breeding Sources

County and state health officials announced today that mosquitoes in two traps located in the Bethesda area of Montgomery County have tested positive for the West Nile virus. Infected mosquitoes found in the County included for the first time the Asian Tiger mosquito. Asian Tiger mosquitoes, which are smaller than other mosquitoes and have distinctive black-and-white stripes, are more likely to be out during the day.

Officials also stressed that there have been no reported human cases of West Nile virus in Montgomery County this year. More than 50 birds found in the County have tested positive and approximately 2,000 sightings of dead birds have been reported to the state's call-in line (1-866-866-2769).

“We are continually learning more about the West Nile virus and how it is transmitted,” said Lynn Frank, chief of Public Health Services, Montgomery County Department of Health and Human Services. “Finding infected Asian Tiger mosquitoes indicate that we need to be more vigilant about protecting ourselves from mosquito bites at all times during the day and continue working hard to get rid of mosquito breeding sites.”

"Maryland citizens need to continue their proactive measures in reducing the mosquito population," said Dr. Tracy DuVernor, Acting State Public Health Veterinarian. "The simple act of emptying containers with standing water in and around the yard can help eliminate breeding grounds for mosquitoes."

Mosquitoes that feed on infected birds may carry West Nile virus. They transmit the virus to humans, birds and some other mammals. West Nile virus can cause a range of illnesses—from mild flu-like symptoms to encephalitis, brain infections and even death. Most people, however, can be infected and have no symptoms at all.

According to health officials, getting rid of places where mosquitoes breed is the most important prevention measure to take.
