Bridgeport officials are urging residents to be mindful of mosquitoes after a resident was hospitalized with West Nile virus.

Experts say eight out of 10 people infected with West Nile virus don't have symptoms. Only a small percentage of mosquitoes carry the virus, but the Connecticut Agricultural Experiment Station found higher numbers in Fairfield County over the past month.

Dr. Albert Shaw, an infectious disease doctor with Yale Medicine, says that in rare cases, West Nile virus can turn into West Nile meningitis or encephalitis.

Health officials say there will be less infections if mosquitoes have less places to breed, so people are encouraged to treat any standing water near their home.

Bridgeport's acting health director, Ebony Jackson-Shaheed, says older or immunocompromised residents will want to be extra careful about avoiding bites.

Shaw says it's a case where an ounce of prevention may be worth a pound of cure.

The Connecticut Agricultural Experiment Station says out of over 261,000 mosquitoes tested in the state so far this year, 110 of them had West Nile virus.

Health officials say a West Haven resident also tested positive for West Nile virus.
