Ketchikan local authorities say another person has tested positive for the coronavirus in the community. The latest case is someone who was in close contact with another known case, officials said.

State public health nurses are investigating the new patient’s recent contacts.

This latest case announced Monday brought Ketchikan’s total cases to 16 — though all but one have recovered, and state health authorities say they no longer need to be monitored.

Meanwhile, the Prince of Wales Island community of Craig announced Monday that both confirmed cases in that community had recovered. That means health authorities aren’t aware of any active COVID-19 cases on Prince of Wales Island.

As of the state’s last update at noon Monday, the coronavirus has infected at least 321 Alaskans. Of those, 36 have required hospitalization and nine have died. At least 161 Alaskans have recovered from COVID-19.

Officials encourage anyone who shows symptoms of COVID-19, like a fever or cough, to call their healthcare provider or the Ketchikan testing hotline at 225-TEST (225-8478).
