Summary and assessment for week 18

Severe COVID-19 disease

  • There has been a steady decline in the number of new patients admitted to hospitals with COVID-19 as the main cause in recent weeks. So far, 62 new patients have been reported in week 18 after 79 in week 17. The number of new patients admitted to hospital last week is expected to be adjusted upwards.
  • In week 18, the number of new patients admitted per 100,000 people was highest in the age groups 75 years and older. The incidence was relatively stable or declining in all age groups.
  • Five new patients have been reported so far in intensive care in week 18, after nine in week 17. The number of new patients admitted to intensive care last week is expected to be adjusted upwards.
  • There are a total of 3,061 deaths up to 8 May 2022. There are currently 37 deaths registered in week 18 after 70 in week 17. The figures for the last weeks, especially the last week, are expected to be adjusted upwards. In week 18, the median age was 84 years (lower-upper quartile: 77-92 years), and 59% died at a health institution other than a hospital, primarily a nursing home.
  • In 2022, there were more deaths than expected in weeks 8, 11, 12 and 14 in the population in Norway as a whole and in the age group 65 years and older.

Reported COVID-19 cases, test activity and cold symptoms in the population

  • Data from the population survey Symptometer show that since week 8 there has been a weekly decrease in the proportion of participants who report cold symptoms and the proportion who report that they have been tested. The proportion reporting a positive test result has also been declining since week 8 but shows a small increase in week 18.
  • The proportion of consultations at the doctor's office / emergency room for confirmed COVID-19 was increasing until week 8 and has been declining since then.
  • There has been a decrease in the number of cases reported to MSIS since week 8.
  • The number of people tested with PCR / rapid antigen tests in the health service has been declining since week 3. Most are tested, in relation to the population, among people aged 80 and older.
  • The number of notified outbreaks in the health service has been declining since week 9 (69 notifications). In week 18, 3 outbreaks were announced in the healthcare service.

Vaccination against COVID-19

  • As of 8 May 2022, 73% of the entire population, 88% (16 years and older) and 89% (18 years and older) have been vaccinated with two doses of coronavirus vaccine. A total of 84% of 16-17 year-olds and 55% of 12-15 year-olds have been vaccinated with one dose, and 44% of 16-17 year-olds have been vaccinated with a second dose.
  • 53% of the entire population has received a booster dose (3rd dose). The proportion is 90% for all 65 years and older, 82% for those over 45 years and 66% for the age group 18 years and older. Among the risk groups, 82% of the people aged 18-64 with a high risk of a severe disease course have received a booster dose (3rd dose), and 74% of those with a moderate risk. Among people 80 years and older, 2% are vaccinated with the 4th dose.

Virological monitoring

  • Omicron BA.2 overtook omicron BA.1 in week 6 nationally and now accounts for 100% of all whole-genome sequences in the last two weeks. Some variants of interest and variants on the monitoring list have been detected sporadically in Norway recently, including one case of BA.5.

Mathematical modelling

  • Mathematical modelling indicates that the infection rate is declining with an average reproduction number from 4 April of 0.8 (0.5 - 1.0).

Assessment for week 18

  • An overall assessment of available surveillance data continues to show a declining trend for the COVID-19 epidemic, but probably not as steep as in March and April.

  • High vaccination coverage contributes to protection against severe COVID-19. The omicron variant also has lower inherent virulence. The risk of a severe disease course is therefore very low for most infected people. Severe COVID-19 especially affects unvaccinated people and vaccinated people who are elderly or have underlying diseases. It is still important that unvaccinated people start their vaccination, and that people over the age of 45 and medical risk groups over the age of 18 take a booster dose. The municipalities must make this available.

  • The epidemic peaked in week 8, and a continued decline in patient admissions due to COVID-19 is expected in the coming weeks. The trend in admissions for influenza is also declining.

  • The COVID-19 pandemic is still ongoing. Although the epidemic in Norway is now returning, there is a need for continued surveillance, preparedness and plans to meet any changes in the situation. There is still a risk of new waves of COVID-19 with omicron-like variants or with completely new, more virulent variants that may also escape today's vaccines. The municipalities must follow the situation and be vigilant for the aggravation of the epidemic, and the health institutions must be prepared for handling outbreaks in line with the government's updated strategy of 5 April.
