Mosquito-testing season has begun in Connecticut and public health officials have added a new virus to their monitoring list this year: Zika.
Zika joins a list of other diseases the state is already on the lookout for -- viruses like West Nile and Eastern Equine Encephalitis.
In an email, a spokesperson for the Department of Public Health said so far, seven cases of Zika in humans have been reported in Connecticut -- including two cases in pregnant patients.
All cases of Zika in the state were contracted while outside of the country in Central or South America, the Caribbean or Puerto Rico.
Zika is mainly transmitted by the yellow fever mosquito, which doesn't occur in Connecticut. It can also be carried by the Asian Tiger mosquito, which has been identified in lower Fairfield and New Haven counties.
The DPH said mosquitoes will be trapped and tested in more than 70 towns from now through October.
