New COVID-19 cases - Weekly review: 23 - 29 November

The number of people testing positive for COVID-19 continues to decrease slightly, but remains at a high level, with 3,565 cases for the week of 23-29 November, compared to 3.851 cases for the previous week (-8%). However, the number of identified contacts has increased significantly to 16,052 (+7%), due in particular to the substantial reinforcement of the contact tracing team.

The average age of those diagnosed as COVID-19 positive decreased from 39.8 to 38.8 years.

The number of PCR tests performed during the week of 23 to 29 November was 69,558 compared to 69,680 for the previous week.

As of 29 November, the number of active infections was 8,362 (compared to 9,010 on 22.11.), while the number of people healed increased from 21,829 to 25,995. During the week in question, there were 47 new deaths related to COVID-19, compared to 38 the previous week. The average age of the deceased is 80 years.

For the week of 23 to 29 November, 176 hospitalisations in normal care and 43 hospitalisations in intensive care of COVID patients were confirmed, compared to 186 and 45 respectively the previous week. ​

The effective reproduction rate (R) went from 1.00 to 0.98 while the positivity rate on the tests carried out was 5.13%, against 5.53% the previous week (average of the week).

The 7-day incidence rate is 569 cases per 100,000 residents, respectively 1,184 cases per 100,000 inhabitants over 14 days. Note that for the week of 16 November, the incidence rate was 615 cases per 100.000 inhabitants over 7 days.

It has continued to increase in the 0-14 age group, while in all other age groups and consequently in the general population the downward trend continues. At this stage, the incidence in all age groups is very similar, with the exception of the 60-74 age group, which has a lower incidence.

Quarantine and isolation

For the week from 23 to 29 November, 7,640 people were in isolation (-5%) and 11,203 in quarantine (+21% compared to the previous week).


The rate of contaminations for which the source of contamination is not clearly attributable has decreased.

According to the analysis carried out over two full days (23 - 24/11) and covering 988 cases, the family circle remains the most frequent source (39.7%) of COVID-19 infections.

Wastewater monitoring in Luxembourg as part of SARS-CoV-2

The latest CORONASTEP report drawn up by the LIST (Luxembourg Institute of Science and Technology), indicates that during the week of 23 to 29 November, SARS CoV-2 flows in wastewater remain high. However, the data collected seems to validate the downward trend observed last week, although it is still weak. This trend will have to be confirmed in the coming days or weeks.

All CORONASTEP reports are available on the LIST website:
