The Boston Public Health Commission reported that three more mosquito pools tested positive for the West Nile Virus in West Roxbury.

This is the second time this summer mosquito pools have tested positive in West Roxbury for the West Nile Virus (WNV). On July 8, two positive mosquito pools were also found in West Roxbury. 

The most recent tests also revealed that one mosquito pool from Dorchester also tested positive for WNV. Health officials do not release where positive test results are found.

The mosquito traps were collected Tuesday, July 12, according to Boston health officials.

There have are no confirmed human cases of WNV in Boston this year, and WNV is regarded as a low-risk virus.

"It’s that time of year when it’s not uncommon to find mosquitoes infected with the West Nile Virus in the Boston area,’’ said Dr. Anita Barry, director of the Infectious Disease Bureau at the Public Health Commission.

WNV is most commonly transmitted to humans by mosquitoes infected with the virus, said Barry. 

Here are some ways to lower your risk even more from the BPHC:

• Using insect repellant when outdoors, especially from dusk to dawn when mosquitoes are more likely to be biting.
• Wearing clothing with long sleeves and pants, when possible.
• Mosquito-proofing your home by ensuring that window and door screens are in good repair to prevent mosquitoes from getting into the house.
• Preventing mosquitoes from breeding in standing water by turning over unused flower pots, buckets, wheelbarrows, and garbage cans; removing leaves and other debris that can clog gutters and trap water; disposing of or covering old tires; and covering swimming pools and kiddie pools when not in use.
