State health experts say mpox, formerly known as monkeypox, is popping up again.

They say 11 cases have been reported this year in Connecticut, compared to last year when there were only four.

In 2022, there was an outbreak with 145 cases.

The state’s public health department says in order for at-risk people to be fully protected against the disease, one dose of the vaccine is not enough. It recommends getting two doses.

"When we look at data across the United States, there are people who have received one dose and then had an active infection with mpox,” said Dr. Manisha Juthani, the commissioner of the Connecticut Department of Public Health.

The CDC says there have been over 1,300 reported cases across the country this year.
