A Greenwich resident has tested positive for West Nile virus, according to the Greenwich Department of Health.
The patient is between the ages of 70-79 and became ill in mid-August with a fever, headache and some neurological symptoms.
"This case of human illness demonstrates that WNV can cause serious illness and whenever the virus is present, there is a potential for human infection," said Caroline Baisley, Director of Health in Greenwich.
This is the fifth human West Nile virus infection in Connecticut this season. Two people from Stamford, a person from New Haven and another from Bridgeport all contracted the disease earlier this summer.
West Nile virus is transmitted through the bite of an infected mosquito. Experts say the threat of West Nile virus will continue until the first frost of the season kills off the mosquito population.
