Another two people have tested positive for the coronavirus in Ketchikan. That’s according to a statement from the Ketchikan Emergency Operations Center.

The two new positive patients were in close contact with someone known to have the coronavirus, officials say. They were tested as part of the contact investigation into another positive case. The two patients were in quarantine when they were tested; they’ve since been placed into isolation. Public health nurses are monitoring their condition.

Officials say the two nonresidents are in Ketchikan for work. They’re not currently showing symptoms, according to the statement.

A total of 30 residents, visitors and out-of-state workers have tested positive in Ketchikan as of Monday afternoon. Some 25 of the 30 have recovered. Coronavirus infections in Alaska have climbed rapidly in recent weeks, with most of the activity in the Southcentral portion of the state.

Free coronavirus testing is available in downtown Ketchikan every Wednesday and Thursday. It’s open to anyone with even mild symptoms. High-risk individuals and their caregivers are eligible for testing even without symptoms.
