Weekly update on the coronavirus SARS-CoV-2: 31 January 2023

In the Infection Radar survey, the percentage of participants who reported possible symptoms of COVID-19 last week increased slightly compared to the week before that (from +3.0% to +3.3%). The percentage of Infection Radar participants who tested positive for COVID-19 remained the same (staying at +0.6%) compared to the week before that. In addition, the number of people who tested positive for COVID-19 reported to the Municipal Public Health Services (GGDs) increased slightly (+11%) last week, and the number of people tested by the GGD also increased slightly (+8%). The number of nursing home residents who tested positive for COVID-19 increased last week (+16%). On 17 January 2023, the reproduction number based on reported positive tests was 0.96 (0.74 – 1.21). The number of new hospital admissions of patients with SARS-CoV-2 decreased (-18%) compared to the week before. The number of new ICU admissions of patients with SARS-CoV-2 increased slightly. There were 20 ICU admissions last week, compared to 19 ICU admissions the week before.

Weekly update on the coronavirus SARS-CoV-2: 24 January 2023

As of 16 September 2022, the Coronavirus Dashboard provided by the national government also includes the coronavirus thermometer. The thermometer offers a visual representation of pressure on society and healthcare as a result of the coronavirus SARS-CoV-2. The coronavirus thermometer is based on the epidemiological situation and the associated RIVM analysis.

The RIVM Response Team advises coronavirus thermometer: status 1 – low (Limited pressure on healthcare chain and society)

Infection Radar, testing, and hospital and ICU admissions

In the Infection Radar survey, the percentage of participants who reported possible symptoms of COVID-19 last week decreased (from +3.4% to +3.0%) compared to the week before that. The number of Infection Radar participants who tested positive for COVID-19 also decreased (from +0.8% to +0.6%) compared to the week before that. In addition, the number of people who tested positive for COVID-19 reported to the Municipal Public Health Services (GGDs) decreased (-25%) last week, and the number of people tested by the GGD also decreased (-36%). The number of nursing home residents who tested positive for COVID-19 decreased (-35%) last week. On 10 January 2023, the reproduction number based on reported positive tests was 0.83 (0.64 – 1.03). The number of new hospital admissions of patients with SARS-CoV-2 decreased (-25%) compared to the week before. The number of new ICU admissions of patients with SARS-CoV-2 also decreased. There were 19 ICU admissions last week, compared to 29 ICU admissions the week before.

Sewage surveillance

In week 2 (9 - 15 January 2023),  sewage surveillance showed that the national average viral load decreased by 33% compared to the week before. In the first half of week 3 (16 – 18 January 2023), the average viral load continued to decrease, dropping by 34%. The Omicron sub-variant BQ.1 was detected most frequently in sewage. More recombinants (variants that combine properties of multiple SARS-CoV-2 variants) and Omicron BA.2 sub-variants were also detected, including BA.2.75 and its sub-variants.

Virus variants from pathogen surveillance

Since early 2022, pathogen surveillance has shown that most of the variants of SARS-CoV-2 circulating in the Netherlands are in the Omicron lineage: sub-variants BA.1 through BA.5. Mutations are also emerging within these sub-variants. The same pattern is occurring in other countries as well.

Omicron BA.1 and BA.2 were initially dominant in the Netherlands, followed by BA.5; since week 48 of 2022, BQ.1 (including BQ.1.1) has been responsible for the highest number of infections. A downward trend is now emerging in infections involving BQ.1 (and BQ.1.1). We are seeing an increase in BA.2.75 and recombinant XBB (a variant that combines properties of various Omicron sub-variants). The sub-variant that has been rising sharply in the USA, known as XBB.1.5, is also increasing in the Netherlands. At this time, there are no indications that these sub-variants would be more likely to cause severe illness compared to previous Omicron sub-variants.

The latest calculations suggest that BQ.1 may remain dominant in the Netherlands for several more weeks. The percentages of sub-variants BA.2.75 and XBB (including XBB.1.5) are also increasing, so it is possible that multiple sub-variants may continue circulating simultaneously for some time. New variants or sub-variants may also emerge.

COVID-19 vaccination for 5-11 years only for children in medical high-risk groups

It is no longer necessary to offer COVID-19 vaccination to all children aged 5-11 years. This advisory opinion of the Health Council was adopted by Minister Kuipers of Ministry of Health, Welfare and Sport (VWS) (only in Dutch) on 19 January 2023. Accordingly, as of 23 February 2023, invitations for COVID-19 vaccination will only be sent to children in this age group who have an elevated risk of severe illness due to COVID-19.

58% lower risk of COVID-19 hospitalisation among over-60s who had the autumn vaccination

In the period from 3 October 2022 to 9 January 2023, the risk of hospital admission for people aged 60 years and older who received a repeat vaccination against COVID-19 in the autumn round was 58% lower than for people who had previously received at least one COVID-19 vaccination, but had not received a repeat vaccination in the autumn round. The risk of ICU admission for over-60s who received the repeat vaccination in the autumn round was 59% lower. This means that the risk of hospital and ICU admission for people over 60 who received the repeat vaccination in autumn 2022 was nearly 2.5 times lower.

Vaccination figures for autumn round of COVID-19 repeat vaccination

From 19 September 2022 to 15 January 2023, more than 4.1 million repeat vaccinations against COVID-19 were administered. Vaccination coverage for the repeat vaccination among people over 60 has now reached 59.9%. The number of repeat vaccinations administered in the second calendar week of 2023 was slightly lower than in the first week, but still higher than in the last two weeks of 2022.

The repeat vaccination is available to everyone aged 12 years and older who has completed the basic series of COVID-19 vaccinations. People can get the repeat vaccination starting from 3 months after their last COVID-19 vaccination or 3 months after a SARS-CoV-2 infection. You can make an appointment via planjeprik.nl. Walk-in vaccinations are also possible at more and more locations. For more information, see www.prikkenzonderafspraak.nl.

Infection Radar, testing, and hospital and ICU admissions

In the Infection Radar survey, the percentage of participants who reported possible symptoms of COVID-19 last week decreased compared to the week before that(from +5.5% to +3.4%). The number of Infection Radar participants who tested positive for COVID-19 also decreased (from +1.3% to +0.8%) compared to the week before that. In addition, the number of people who tested positive for COVID-19 reported to the Municipal Public Health Services (GGDs) decreased (-47%) last week, and the number of people tested by the GGD also decreased (-45%). The number of nursing home residents who tested positive for COVID-19 decreased (-48%) last week*. On 3 January 2023, the reproduction number based on reported positive tests was 0.73 (0.60 – 0.87). The number of new hospital admissions of patients with SARS-CoV-2 decreased (-34%) compared to the week before. The number of new ICU admissions of patients with SARS-CoV-2 also decreased. There were 29 ICU admissions last week, compared to 47 ICU admissions the week before.

Sewage surveillance

In week 1 (2 - 8 January 2023),  sewage surveillance showed that the national average viral load decreased by 46% compared to the week before. In the first half of week 2 (9 – 11 January 2023), the average viral load continued to decrease, dropping by 31%. The BA.5 Omicron sub-variant, including its sub-variant BQ.1, was detected most frequently in sewage. More recombinants (variants that combine properties of multiple SARS-CoV-2 variants) and Omicron BA.2 sub-variants were also detected, particularly BA.2.75 and its sub-variants.

The percentages of sub-variants BA.2.75 and XBB (including XBB.1.5) are also increasing, so it is possible that multiple sub-variants may continue circulating simultaneously for some time. New variants or sub-variants may also emerge.

Vaccination figures for autumn round of COVID-19 repeat vaccination

From 19 September up to and including 1 January 2023, more than 4 million repeat vaccinations against COVID-19 were administered. Vaccination coverage for the repeat vaccination among people over 60 has now reached 59.0%.

The repeat vaccination is available to everyone aged 12 years and older who has completed the basic series of COVID-19 vaccinations. People can get the repeat vaccination starting from 3 months after their last COVID-19 vaccination or 3 months after a SARS-CoV-2 infection. You can make an appointment via planjeprik.nl. Walk-in vaccinations are also possible at more and more locations. For more information, see www.prikkenzonderafspraak.nl.

Weekly update on the coronavirus SARS-CoV-2: 3 January 2023

As of 16 September 2022, the Coronavirus Dashboard provided by the national government also includes the coronavirus thermometer. The thermometer offers a visual representation of pressure on society and healthcare as a result of the coronavirus SARS-CoV-2. The coronavirus thermometer is based on the epidemiological situation and the associated RIVM analysis.

The RIVM Response Team advises coronavirus thermometer: status 1 – low (Limited pressure on healthcare chain and society)

Infection Radar, testing, and hospital and ICU admissions

In the Infection Radar survey, the percentage of participants who reported possible symptoms of COVID-19 last week decreased slightly compared to the week before that (from +7.3% to +6.7%). The number of Infection Radar participants who tested positive for COVID-19 increased very slightly (from +1.7% to 1.8%) compared to the week before that. In addition, the number of people who tested positive for COVID-19 reported to the Municipal Public Health Services (GGDs) decreased somewhat (-7%) last week, and the number of people who were tested for COVID-19 by the GGD also decreased (-32%). The number of nursing home residents who tested positive for COVID-19 decreased last week (-18%).

On 20 December 2022, the reproduction number based on reported positive tests was 0.86 (0.76 – 0.97). The number of new hospital admissions of patients with SARS-CoV-2 increased significantly (+59%) compared to the week before. The number of new ICU admissions of patients with SARS-CoV-2 also increased significantly. There were 63 ICU admissions last week, compared to 42 ICU admissions the week before.  

It is likely that hospital and ICU admissions in the previous week were underestimated due to a delay in reporting during the Christmas period. As a result, the relative increase in hospital and ICU admissions between weeks 51 and 52 is probably lower.

Sewage surveillance

In week 51 (19 - 25 December 2022), sewage surveillance showed that the national average viral load increased compared to the week before (+33%). In the first half of week 52 (26 and 27 December 2022), the average viral load decreased (-21%).  BQ.1 and its sub-variants were detected most frequently in sewage surveillance. More recombinants and Omicron BA.2 sub-variants were also found, particularly BA.2.75 and its sub-variants, as well as recombinants like XBB.

Virus variants from pathogen surveillance

Since early 2022, pathogen surveillance has shown that most of the variants of SARS-CoV-2 circulating in the Netherlands are in the Omicron lineage: sub-variants BA.1 through BA.5. Mutations are also emerging within these sub-variants. The same pattern is occurring in other countries as well.

Omicron BA.1 and BA.2 were initially dominant in the Netherlands, followed by BA.5; since week 48, BQ.1 (including BQ.1.1) has been responsible for the highest number of infections. We are also seeing an increase in BA.2.75 and recombinant XBB (a variant that combines properties of various Omicron sub-variants). At this time, there are no indications that these sub-variants would be more likely to cause severe illness compared to previous Omicron sub-variants.

The latest calculations suggest that BQ.1 may remain dominant in the Netherlands for some time. The percentages of sub-variants BA.2.75 and XBB are also increasing, so it is possible that multiple sub-variants may continue circulating simultaneously for some time. New variants or sub-variants may also emerge.
