Weekly update on the coronavirus SARS-CoV-2: 29 November 2023

Spread of the virus and admissions

In week 47 (20 –26 November 2023), sewage surveillance showed that the national average viral load increased slightly (+12%) compared to the week before. Last week, the percentage of participants who tested positive for COVID-19 in the Infection Radar survey(link is external) increased slightly (from 2.0% to 2.2%)* compared to the week before that. The daily average number of hospital admissions of patients with SARS-CoV-2 last week also increased slightly compared to the week before that (daily average admissions went from 97 to 102).** There were an average of 500 patients with SARS-CoV-2 in hospital last week; this is comparable to the week before that (average of 505 patients).

Recently, an upward trend has been observed in COVID-19 figures: viral load in sewage, percentage of Infection Radar survey participants with a positive test result, and hospital admissions. This is consistent with the seasonal period in which respiratory infections caused by various viruses are more likely to be circulating.

The latest situation update on SARS-CoV-2 variants is available here.

Weekly update on the coronavirus SARS-CoV-2: 6 December 2023

Starting on 6 December 2023, this update will be published weekly at 16:00 instead of 15:00.

Spread of the virus and admissions

In week 48 (27 November – 3 December 2023), sewage surveillance showed that the national average viral load increased (+23%) compared to the week before. Last week, the percentage of participants who tested positive for COVID-19 in the Infection Radar survey(link is external) increased slightly (from 2.2% to 2.4%)* compared to the week before that. Hospital admissions of patients with SARS-CoV-2 last week also increased slightly compared to the week before that (daily average admissions went from 102 to 108).** There were an average of 541 patients with SARS-CoV-2 in hospital last week; this is comparable to the week before that (average of 522 patients).

The average number of hospital admissions remained stable in recent weeks. However, the figures for the past few days show an increase in hospital admissions (source: LCPS). This is not yet reflected in this weekly update.

In the period from 9 October to 20 November 2023, people over 60 who received a COVID-19 vaccination this autumn had a 77% lower risk of hospital admission due to COVID-19 compared to people who had been vaccinated previously, but had not (yet) received this repeat vaccination. The vaccination is available until 22 December 2023 .

Current situation: BA.2.86 sub-variants are most prevalent in the Netherlands

Since early 2022, most of the variants of SARS-CoV-2 circulating in the Netherlands have been in the Omicron lineage: sub-variants BA.1 through BA.5. Mutations are still emerging within these sub-variants. There are also recombinant strains that combine characteristics of other variants, such as the XBB variants, (including XBB.1.5, XBB.1.9, XBB.1.16 and EG.5). The same pattern is occurring in other countries as well.

Multiple sub-variants of BA.2 and BA.5 are currently circulating in the Netherlands. From BA.2, for example, we are seeing sub-variant BA.2.75 (including CH.1.1). Sub-variants of BA.5 include BF.7 and BQ.1 (including BQ.1.1). There are also recombinant strains that combine characteristics of other variants, such as the XBB variants (including XBB.1.5, XBB.1.9, XBB.1.16 and EG.5).

From week 7 to week 45 of 2023, EG.5 was responsible for the highest number of infections in the Netherlands. EG.5 is an XBB.1.9 sub-variant that was recently designated by the World Health Organisation (WHO) as a ‘Variant of Interest’ (VOI), due to possible changes in characteristics compared to previous variants.

Since week 46, the most common variant seen in pathogen surveillance is BA.2.86, a BA.2 sub-variant which has also been designated as a VOI by the WHO. This variant shows many genetic differences compared to the other variants currently circulating internationally, and is therefore being closely monitored worldwide. 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 trends seen in sewage generally correspond to the trends observed in pathogen surveillance. The main variant currently observed is BA.2.86, and various XBB variants are still being found.

50 XDD in 13 countries now.

We have an unprecedented situation in the Netherlands. JN.1 is probably taking over this week, which is expected to boost cases. But  at the same time sewage concentrations of SARS-CoV-2 are already climbing and near an all time high. Ideal for co-infections and recombinants!

By the way, the percentage of positive tests has never formed a plateau either. And cases have only done so in the elderly. Please note that the denominator is people who have filled in a form that week, including the ones that didn't test. https://coronadashboard.rijksoverheid.nl/landelijk/infectieradar

Weekly coronavirus update SARS(severe acute respiratory syndrome)-CoV(coronavirus)-2: December 13, 2023
Spread of the virus and withdrawals
In week 49 (4-10 December), the national average number of virus particles in sewage water rose sharply by 57% compared to the previous week. Last week, the share of participants with a positive corona test result in Infection Radar(external link) increased compared to the week before (2.4% to 3.1%)*. The number of hospital admissions of patients with SARS-CoV-2 also increased compared to the previous week (daily average number of admissions from 108 to 143).** Last week there were an average of 686 patients with SARS-CoV-2 in hospital; this is higher than the week before (average 541 patients).

DJ...very bad

Weekly update on the coronavirus SARS-CoV-2: 20 December 2023

Spread of the virus and admissions

In week 50 (11 – 17 2023), sewage surveillance showed that the national average viral load increased (+16%) compared to the week before. Last week, the percentage of participants who tested positive for COVID-19 in the Infection Radar survey(link is external) increased slightly (from 3.1% to 3.6%)* compared to the week before that. Hospital admissions of patients with SARS-CoV-2 last week also increased slightly compared to the week before that (daily average admissions went from 143 to 163).** There were an average of 881 patients with SARS-CoV-2 in hospital last week; this is higher than the week before that (average of 686 patients).

The figures for the past few days show an increase in hospital admissions (source: LCPS) , positive test results in the Infection Radar survey, and the number of virus particles in sewage.

Besides SARS-CoV-2, other viruses and bacteria are currently also causing respiratory infections. For more details, see the latest situation update on respiratory viruses in the Netherlands (in Dutch).

The latest situation update on SARS-CoV-2 variants is available here. The next update on SARS-CoV-2 variants will be posted after the holidays, on Wednesday 3 January 2024.

DJ, both CoViD and Flu statistics for NL are "high" however healthcare -so far- not in any form of crisis (yet) here in NL.

Very likely there must be a lot of "co-spread/co-infection" of both CoViD and Flu...Limited testing may see "flu" while in fact a person may have CoViD...

Recently I hardly see any stories on CoViD in non-human hosts...maybe I miss them ?

There has been a blue tongue infection in a NL farm dog...severe one...I believe it was a mixed-farm...also the sheep and cows had a blue tongue infection...[url]https://www.wur.nl/en/research-results/research-institutes/bioveterinary-research/show-bvr/bluetongue-found-in-dutch-dog.htm[/url] or https://www.wur.nl/en/research-results/research-institutes/bioveterinary-research/show-bvr/bluetongue-found-in-dutch-dog.htm

Weekly update on the coronavirus SARS-CoV-2: 3 January 2024

Spread of the virus and admissions

In the first 4 days of week 52 (25 – 28 December 2023), sewage surveillance showed that the national average viral load decreased (-35%) compared to the week before. Last week, the percentage of participants who tested positive for COVID-19 in the Infection Radar survey(link is external) decreased (from 3.4% to 2.6%)* compared to the week before that. Hospital admissions of patients with SARS-CoV-2 last week also decreased slightly compared to the week before that (daily average admissions went from 165 to 141).** There were an average of 784 patients with SARS-CoV-2 in hospital last week; this is lower than the week before that (average of 856 patients).

Due to the holidays, less complete data can be provided on sewage surveillance, the Infection Radar survey and hospital admissions. However, there has been a visible decrease in average viral load, Infection Radar survey results and hospital admissions in the last week of 2023.

Besides SARS-CoV-2, other viruses and bacteria are also causing respiratory infections.

DJ, lots of data was NOT reported ...we may have THREE mass spread events...christmas, new year and schools/workplaces reopening monday january 8...all 1 week apart...

I love to see a reason for optimism...The RIVM site showed the decrease of sewage viral load may be based on data not being reported....However 22/23 season also did see a "peak" for sewage in week 51...

DJ-Are we supposed to believe this is a new normal ? This is where we should be ?
