A mosquito pool in West Roxbury has tested positive for the West Nile Virus, according to the Boston Public Health Commission. 

Previously, one positive mosquito pool was found in Roslindale. There have been no confirmed human cases of the West Nile Virus in Boston this year, reported the Commission.

The location of the positive mosquito pool is not made public so people are aware of the virus. The West Nile Virus is most commonly transmitted to humans by a mosquito infected with the virus, but it poses very low risk to humans.

The city has also put larvicide in catch basins in Boston neighborhoods to reduce the number of mosquitoes.

“It’s again the time of year when it’s not surprising to find mosquitoes infected with West Nile Virus in Boston,” said Dr. Anita Barry, director the Infectious Disease Bureau at the Public Health Commission via press release.  “The recent combination of hot weather and rain may have contributed to West Nile appearing slightly earlier this year than in some previous years, and people should take some simple precautions to avoid mosquito bites.”

Follow these tips for protecting yourself against mosquito bites: 

• Use insect repellant when outdoors, especially from dusk to dawn when mosquitoes are more likely to be biting. 
• When possible wear clothing including long sleeves and pants. 
• Mosquito-proof your home by making sure window and door screens are in good repair to prevent mosquitoes from getting into the house.
 

To prevent mosquitoes from breeding, BPHC advises:

• Turn over unused flower pots, buckets, wheelbarrows, and garbage cans. 
• Remove leaves and other debris that can clog gutters and trap water.
• Dispose of, or cover old tires.
• Cover swimming pools and kiddie pools when not in use.
