Connecticut’s Gov. Ned Lamont announced Friday he will begin self-quarantining after a senior staffer tested positive for COVID-19.

“The governor will immediately begin the process of self-quarantining, as will multiple members of the governor’s senior staff,” his office said in a statement obtained by the Connecticut Post.

The governor’s chief spokesperson, Max Reiss, identified himself as the staffer who had tested positive; in a Tweet late Friday he said he and his family members are quarantining and are all symptom free.

It’s unclear whether Lamont had been in close contact with the staffer, but his office said contact-tracing efforts were underway.

“We are taking this case seriously and observing all protocols to keep the governor, his family, and all of our staff members and their families safe,” Chief of Staff Paul Mounds said in a statement.

“While this is the first case within our administration, tens of thousands of Connecticut residents have experienced COVID-19, and thousands of others have lost their lives.

Mounds noted that Lamont and his senior staff get tested twice a week — and there were no other known cases as of Friday.

Lamont’s self-quarantine comes after several other states’ top lawmakers have battled the infectious disease.

Nevada Gov. Steve Sisolak, Ohio Gov. Mike DeWine, Oklahoma Gov. Kevin Stitt and Virginia Gov. Ralph Northam have all tested positive for the virus.
