Alaska Department of Health and Social Service Weekly COVID-19 and Influenza Update
January 23 – January 29, 2022

Key Findings

• The incidence of COVID-19 remained very high across most parts of Alaska during the week of January 23–January 29, 2022, though the incidence began to decline in some areas.  
• Appreciable levels of influenza transmission began occurring in mid-December and have continued to remain above baseline since then.
• Other respiratory viruses are circulating in addition to SARS-CoV-2 and influenza virus.

COVID-19

COVID-19 Case Trends

• High levels of COVID-19 transmission are occurring throughout much of Alaska and the number of reported cases last week was very similar to the number reported the previous week. Hospital admissions of persons with COVID-19 continue to increase. Hospital admissions are known to be a lagging indicator. 
• 15,752 cases were reported in Alaskans the week of January 23–January 29. This is a 2.2% decrease from the number of cases reported the week before.
• The number of reported COVID-19 cases last week was higher in the Matanuska-Susitna and Kenai Peninsula Boroughs compared to the previous week. The number of reported cases from the Fairbanks North Star Borough last week was similar to the number the week before. The number of reported cases from the Municipality of Anchorage has declined two weeks in a row, suggesting a sustained downward trajectory. The number of cases reported from the City and Borough of Juneau last week was lower than the number reported the previous week.
• The intensity of COVID-19 transmission varies between communities outside the largest boroughs. COVID-19 cases may be declining in some boroughs and census areas while others continue to have an upward trajectory. Regardless of the trajectories, many are at levels of weekly case counts not seen before the Omicron wave. 
• SARS-CoV-2 genome sequencing has confirmed that the Omicron variant is the dominant SARS-CoV-2 variant in Alaska. Visit Alaska’s SARS-CoV-2 Genomics Dashboard to learn more. 
• To learn more about COVID-19 cases, hospitalizations, and deaths due to COVID-19 in Alaska, visit the Cases Dashboard or the monthly report. The cases dashboard includes demographic information on cases and the monthly report includes demographic information on hospitalizations and deaths.

**Rates based on <6 observations are not reported.

COVID-19 and Hospital Capacity

• Hospital capacity is currently very limited because of staff sick calls, supply chain disruptions, and a high number of ill patients.
• The Crisis Care Committee remains active seeking input from, and providing guidance to, health care providers, including allocating, augmenting, or moving constrained resources during this surge to maximize the health of all Alaskans.
• As of January 31, 2022 there were 154 persons with COVID-19 in Alaska hospitals, accounting for 16.3% of all hospitalized persons. Visit the Hospital Dashboard for more data.

COVID-19 and Vaccination

• 69.1% of Alaska residents aged ≥5 years have received at least one dose of a COVID-19 vaccine. Among those who completed the primary vaccine series, 47% of Alaska residents ≥18 years have received their booster. Learn more about COVID-19 vaccination coverage in Alaska on the Vaccine Dashboard.
• Vaccines help protect against infection and against severe disease, especially when a person is up to date on vaccinations. During the 4-week period from January 2, 2022 – January 29, 2022, unvaccinated Alaskans were 6.4 times more likely to be hospitalized due to COVID-19 than Alaskans who are up to date on COVID-19 vaccination (i.e., completed the primary series and received a booster dose, if eligible) and 2.0 times more likely to be hospitalized due to COVID-19 than Alaskans who completed the primary vaccination series but are not up to date. (See the monthly report for more data and analysis through December.)

Unvaccinated Alaskans are 6.4 times more likely to be hospitalized due to COVID-19 than Alaskans who are up to date on COVID-19 vaccination and 2.0 times more likely to be hospitalized due to COVID-19 than Alaskans who completed the primary vaccination series but are not up to date. The absolute rates of hospitalization shown here are likely underestimates because of COVID-19 hospitalizations that have not yet been documented. This analysis provides preliminary evidence of how hospitalization incidence rates vary by vaccination status in Alaska when the Omicron variant is dominant.

• Among Alaska residents aged ≥5 years from January 16, 2021–January 29, 2022, 56,235 cases were documented in persons who had completed the primary series and were considered fully vaccinated. Among those vaccine-breakthrough cases, 424 hospitalizations and 143 deaths due to COVID-19 have been recorded. During that time, 89,537 cases have been documented in unvaccinated Alaskans aged ≥5 years, leading to 1,724 hospitalizations and 574 deaths. All data are preliminary and subject to change.
• During the Omicron wave, cases in vaccinated persons have become more frequent, but Alaskans who are up to date on their COVID-19 vaccines (i.e., completed the primary series and received a booster dose, if eligible) still have lower rates of becoming a case than those who are unvaccinated or are not up to date.

In order to more easily identify changes over time, the definition of “up to date” as of January 8, 2022 was applied to data from all time points. Some COVID-19 cases with specimen collection in the immediate past week (indicated by the grey box) may have not yet been reported or counted.

Influenza (“Flu”)

• Reported influenza cases began increasing in Alaska in mid-December. The number of reported cases the week of January 23–January 29 was similar to the number reported the previous week.
• Right now, most influenza in Alaska is caused by influenza A.
• 23% of Alaskans aged ≥10 years have been vaccinated against seasonal influenza. It is not too late to get vaccinated against influenza.
• Last week, far more cases of influenza were reported from Anchorage than any other region. Learn more in the weekly Alaska Influenza Snapshot.

Emergency Department Visits with COVID-like or Influenza-like Illness

• Syndromic surveillance consists of analyzing data on symptoms and diagnoses among patients visiting emergency departments in Alaska. The main goal is to identify trends. Unlike case-based surveillance, syndromic surveillance does not depend on laboratory testing.
• Influenza-like illness (ILI) is defined as having a fever and at least one other symptom, such cough or sore throat. Patients with a diagnosis of influenza are also included, regardless of symptoms.
• COVID-like illness (CLI) encompasses a broader array of respiratory and other symptoms than influenza-like illness. This category also includes any patient with a diagnosis of COVID-19, regardless of symptoms.
• Patients with a diagnosis of COVID-19 are excluded from the ILI category and, likewise, patients with a diagnosis of influenza are excluded from the CLI category. But a patient without a diagnosis for either could be included in both the CLI and ILI categories. CLI and ILI may be caused by respiratory viruses other than SARS-CoV-2 and influenza virus.
• As the Delta variant wave waned in Alaska in late October and November 2021, the percentage of emergency department patients with CLI declined. However, it has increased over the past few weeks since mid-December, reaching its peak in mid-January. Now, it is at a level similar to that seen at the peak of the Delta wave. The percentage of emergency department patients with CLI the week of January 23–January 29 decreased from the percentage recorded the prior week.
• ILI levels increased in December but have since decreased from the late-December peak.

Take action to protect yourself and your family

• Get vaccinated and stay up to date: COVID-19 vaccines are available for everyone aged 5 and older. Booster shots are available for everyone aged 12 and older if enough time has passed since the initial vaccine series. Getting vaccinated and boosted will help protect you, your family, and your community against COVID-19. Learn more about COVID-19 vaccines. You can visit vaccines.gov or text your zip code to GETVAX (438829) in English, or VACUNA (822862) for Spanish.
• Wear a mask indoors in public: Wearing a well-fitting 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 where this action is needed to protect your health and the health of others. Some masks such as surgical, KN95, or N95 masks provide higher filtration and therefore better protection than cloth face coverings, but only if the mask fits your face well and is worn consistently.
• Practice physical distancing: When possible, avoid crowds and keep your distance from others while in public settings – particularly when indoors.
• Get tested: Seek testing if you have any symptoms or have been exposed to an infected person. If you do test positive, isolate right away and notify your contacts. Ask your contacts to get tested at the appropriate time and, if they are not up to date on COVID vaccination, to quarantine. Learn more about COVID-19 testing.
• Ask a health care provider about treatment: If you test positive and you’re at increased risk for severe COVID, ask a health care provider about treatment options. Treatments can reduce the risk of hospitalization and they work best when given soon after symptoms start. Learn more about COVID-19 treatments and where you can find COVID-19 treatments. Sotrovimab and PAXLOVID® are in short supply nationally and recommended to be reserved for tier 1 patients. Molnupiravir and remdesivir are more widely available. The monoclonal antibody treatments REGEN-COV® and Bamlanivimab/Etesevimab are no longer being shipped by the federal government because they do not work against the Omicron variant.
