Case Trends

  • The number of reported COVID-19 cases in Alaska continued last week on an upwards trajectory.

  • 3,525 cases were reported in Alaskans between August 22–August 28. This is a 9.1% increase from the week before.
  • Cases remain high or are increasing in most parts of the state on the road system (including Kenai Peninsula Borough, Anchorage, Matanuska-Susitna Borough, and Fairbanks North Star Borough).
  • While the intensity of COVID-19 transmission varies substantially between communities off the road system, COVID-19 cases are regularly reported from nearly all boroughs and census areas.
  • The Delta variant has become the dominant SARS-CoV-2 variant in Alaska. This variant transmits more easily than other variants.

COVID-19 Guidance

  • Currently available COVID vaccines will help protect you, your family, and your community against COVID-19, including the Delta variant. Getting vaccinated now is more important than ever.
  • If you do test positive, isolate right away, and notify your contacts. Ask them to get tested and, if they are unvaccinated, to quarantine.
  • Monoclonal antibody treatments are effective and reduce the risk of hospitalization. If you have COVID-19 or are a close contact, talk to a healthcare provider about whether treatment may be right for you. The treatments work best when given early.
  • In areas with substantial or high community transmission, wearing a mask when in indoor public spaces regardless of vaccination status is an important step to take to slow the spread of COVID-19. Most Alaskans live in an area with substantial or high community transmission.
  • Fully vaccinated persons who are close contacts to someone with COVID-19 do not need to quarantine but should get tested 3 to 5 days after exposure and wear a mask in public indoor areas for 14 days or until they receive a negative test result.

Borough/Census Area Alert Level Trends

  • Alert levels are based on the case counts over the past 7 days as well as the daily number of reported cases over the past 7 days per 100,000 population.
  • Alert levels have been changed to more closely mirror CDC’s community transmission indicator and are calculated by borough and census area, rather than by region.

Vaccination Status

  • Anyone aged 12+ in Alaska is eligible to receive a COVID-19 vaccine.
  • If you have received an initial dose of the Pfizer or Moderna COVID-19 vaccine, be sure to get your second dose too. Scientific studies have shown that two doses of an mRNA vaccine are more effective than one dose of an mRNA vaccine, especially against emerging variants of concern.
  • CDC recommends that people with moderately to severely compromised immune systems receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of an mRNA vaccine.
  • Vaccinated persons with immunocompromising conditions should discuss with their health care providers the need for additional personal protective measures.
  • To schedule your vaccine appointment visit or call 907-646-3322.
  • To find clinics in your area you can visit or text your zip code to GETVAX (438829) in English, or VACUNA (822862) for Spanish.
  • The Alaska vaccine dashboard is available online for the most up-to-date data.

New Hospitalizations and Deaths

  • Cumulative hospitalizations increased by 52 to 1,976. Hospitalization reports often lag when a case was initially reported.
  • 16.5% of hospitalized patients in Alaska had COVID-19 as of August 31, 2021.
  • On August 28th, there were 151 persons with COVID-19 in AK hospitals, which is a 14.4% increase relative to the week before when there were 132 persons hospitalized.
  • The cumulative number of COVID-19 deaths among Alaska residents increased by 21 to 427. It is common to take some time for a death to be reported and verified, and deaths that occurred during August 22–August 28 may be reported in the future after death certificates are reviewed.

Vaccine Breakthrough Cases

  • Vaccine breakthrough (VB) infections of COVID-19 are those detected in a person who is at least 2 weeks beyond their second dose of a 2-dose series or the only dose of a 1-dose series.
  • The updated VB data are among Alaskans aged 12+ with a specimen collection date from January 16th through August 28th. 
  • From January 16–August 28, 2021, 16 deaths, 85 hospitalizations, and 5,162 cases with a VB infection were reported among Alaska residents aged 12+. These counts are provisional and subject to change as more data are compiled. In that same time frame, a total of 29,184 cases, 802 hospitalizations, and 121 deaths were reported.
  • 82% of all cases, 89% of all hospitalizations, and 87% of deaths among Alaska residents age 12 and up from January 16 through August 28, 2021 were in people who were not fully vaccinated. 
  • Specimens from VB infections are described in the weekly Alaska Genomics Report. More detailed information about hospitalizations, deaths, and vaccine breakthrough infections among Alaskan residents can also be found in the monthly report.
