Prince of Wales Island update
Three COVID-19 cases were recorded on Prince of Wales Island on Tuesday, according to a message recorded that evening on the Craig Public Health COVID-19 information hotline.
"Two of the cases are residents of Craig," the hotline stated. "Their case investigations remain under investigation."
The third case, attributed to secondary spread, involves a resident of a POW community with fewer than 1,000 residents.
Of POW's cumulative 416 cases, six were active as of Tuesday evening, according to Craig Public Health.
COVID-19 in Alaska
During a virtual question-and-answer session held via Facebook on Wednesday, Alaska's health officials addressed topics including COVID-19 reinfections, and vaccination as a piece of layer mitigation.
DHSS Epidemiologist Louisa Castrodale said that a case is considered to be a second infection if it occurs 90 days after the individual first tested positive for COVID-19.
"It's really interesting to think about ... what a repeat infection means immunologically for that person," she said.
Castrodale said that "there's a lot of interest" in understanding trends regarding the symptoms or sources of infection in the cases of individuals who contract COVID-19 a second time.
And as more of the state's population tests positive during the ongoing pandemic, she said that reinfections will become more common as the number of previously infected individuals also grows.
"Saying that, and looking at our surges, we see people who were a case during the last surge, and here they are, 12 months later, and they're another case," Castrodale said.
DHSS plans to include further information about COVID-19 reinfections in future bulletins and reports.
Also speaking during the same question-and-answer event was State Epidemiologist Joe McLaughlin advocated for the use of layered mitigation measures, as well as vaccination.
McLaughlin said that vaccination is "just another layer of protection to help boost your immune system."
People who have already had COVID-19 should still be vaccinated, McLaughlin said, because it could decrease their risk of another infection.
McLaughlin also noted that "non-pharmaceutical mitigation measures" remain an important tool in the pandemic. This includes mask-wearing and social distancing, as well as keeping track of one's close contacts, testing when not feeling well and keeping to well-ventilated areas.
