Summary and assessment for week 30
- The number of reported cases has increased in weeks 29 and 30, after six weeks with a stable trend. So far, 2,165 cases of covid-19 have been reported in week 30, an increase of 45 % since week 29 (1,494). This amounts to 68 reported cases per 100,000 inhabitants for weeks 29 and 30 combined.
- The total number of people tested (with PCR and antigen rapid tests combined) was 185,367 in week 30, an increase of 14 % from week 29. The proportion of positive results among those tested went up from 0.9 % in week 29 to 1.2 % in week 30. It was between 0.7–1.0 % in weeks 25–28.
- Møre og Romsdal (116 per 100,000) has the most reported cases per 100,000 inhabitants for weeks 29 and 30 combined, after having the fewest for weeks 28 and 29. After Møre and Romsdal, the most reported cases per 100,000 inhabitants were in Vestland (111), Oslo (78) and Troms and Finnmark (78). Last week, there was an increase in the number of reported cases in Møre og Romsdal, Vestfold and Telemark, Vestland, Agder, Rogaland, Oslo, Trøndelag and Viken.
- The incidence of new hospital admissions and intensive care units is still low. Since week 25, there have been reports of between 17–20 new hospital admissions with covid-19 as the main cause, and 5 or fewer new admissions to the intensive care unit per week. There were 6 new admissions in Viken in week 30, and fewer than 5 in other counties.
- There has been a stable and low incidence of deaths in the last 13 weeks. There were 4 deaths with a date of death in week 30, after 0 in week 29.
- The Delta virus variant (B.1.617.2) is now the most common variant in Norway. The number of confirmed cases with Delta has increased from 50 cases up to week 21, to now a total of 3,380 cases up to and including week 30. In recent weeks, a large decrease in the proportion of Alfa variant has been observed from over 90 % before week 20 to 7 % in week 30. At the same time, the proportion of confirmed cases with Delta variant has increased from 1 % in week 18 to 90 % in week 30. There is little infection with variants other than Delta and Alfa. The NIPH’s latest risk assessment on Delta variants is from 26 July.
- As of 1 August 2021, 67 % of the entire population, 83 % of all persons 18 years and older, 93 % of all 45 years and older, and 96 % of all 65 years and older have been vaccinated with at least one dose. 42 % of the population over the age of 18 have received two doses. Among people at high risk for a severe disease course, such as patients with immunodeficiency, transplant recipients or in active cancer treatment, 92 % aged 18–64 years were vaccinated with the 1st dose and 76 % with the 2nd dose. Among people with a moderate risk of severe disease course in the same age group, 90 % were vaccinated with the 1st dose and 64 % with the 2nd dose.
- The epidemic in Norway is under control, but the spread of infection is increasing in several parts of the country. The incidence increased in all age groups last week but is clearly highest among teenagers and younger adults. The incidence of new hospital admissions, intensive care units and deaths remains low, which must be assumed to be due to the vaccines’ protection of the elderly and others with an increased risk of a severe disease course. Although there has now been an increase in the number of cases, and the Delta variant has become dominant in the country, we consider it unlikely that the epidemic will be as large as previous waves and threaten hospitals' capacity. The epidemic must be closely monitored in the coming months, and measures must be balanced against the burden of disease, especially hospital admissions, capacity in the health service and the progress of the coronavirus immunisation program. Municipalities with outbreaks must continue with testing and infection tracking as well as more targeted contact-reducing measures if necessary, while other municipalities must be prepared for such reinforcement at short notice. The coronavirus immunisation in the municipalities must continue at full strength.
More main points from week 30
- In week 30, we see an increase in the number of reported cases in all age groups compared with week 29. Most reported cases in relation to the population in week 30 were observed in the age groups 20–39 years (78 per 100,000) and 13–19 years (74 per 100,000).
- In week 30, there were 121,015 travellers registered in the entry register, an increase from week 29 when 106,786 travellers were registered. The most common departure countries in weeks 29 and 30 were Sweden, Poland and Germany. The number and proportion of cases stated are based on travellers registered with F and D numbers. Data must be interpreted with caution in light of this limitation. The proportion of registered arrivals who tested positive on arrival in week 30 was 0.28 %, corresponding to the level as for week 29 (0.29 %). Among those who arrived in week 29, of registered travellers from green countries / areas, 84 cases (0.27 %) were detected within 10 days of arrival, among registered travellers with a quarantine obligation, 211 cases were registered in the same period (1, 27 %). In week 30, on arrival, the most positive cases were still registered among travellers departing from Spain (21 cases, 0.8 %), followed by travellers departing from Croatia (18 cases, 2.2 %). Data from testing at border stations (independent of travel registration) show a continued increase in the number of cases detected on arrival: this increased from 50 cases in week 27, to 195 cases in week 30. Data from week 26 through week 29 show that 53.9 % of cases are detected within 10 days, and not on arrival.
- In week 30, the National Institute of Public Health has followed up the infection situation with an assessment of measures in Møre og Romsdal, Vestland, Nordland and Troms and Finnmark. In addition, the National Institute of Public Health has in the last week followed up or reported around 10 outbreaks associated with bars and restaurants, health institutions, social gatherings and in households.
