COVID-19 cases - Weekly review: 7 - 13 June

During the week from 7 to 13 June and for the 11th week in a row, the number of people testing positive for COVID-19 continued to decrease from 324 to 189 (-41.6%), while the number of their identified close contacts also decreased from 908 cases the previous week to 742 (-18.2%).

The number of PCR tests performed during the week of 7 to 13 June has slightly decreased from 47,273 to 45,745.

230 people reported a positive rapid antigen test.

As of 13 June, the number of active infections had decreased to 500 (compared to 677 as of 06/06), while the number of people healed increased from 68,761 to 69,127. The average age of those diagnosed as COVID-19 positive remains rather stable at 33 years.

The week of 7 to 13 June was the first week in which no new deaths related to COVID-19 were recorded since the week of 21 to 27 September 2020 (2 deaths were recorded the previous week).

The downward trend continues in hospitals with a decrease from 15 to 12 admissions of confirmed COVID-19 patients in normal care. In intensive care the number of occupied beds decreased from 4 to 2. The average age of hospitalised patients remained stable (54 years).

Positivity rate and incidence rate

For the reference period, the effective reproduction rate (R) decreased from 0.89 to 0.69, as well as the positivity rate on all tests performed (prescription, Large Scale Testing, contact tracing) with 0.41% compared to 0.69% the previous week. A similar trend can be observed for the positivity rate for tests carried out on prescription, i.e. for people with symptoms, which decreased from 1.91% to 1.19%.

The incidence rate clearly continues its downward trend for all age groups, with 30 cases per 100,000 residents over 7 days, compared to 51 cases per 100,000 residents for the week of 31 May. Compared to the previous week, the incidence rate decreases between 40% and 60% in the age groups 0-60 years. During the last week, there were 6 cases with COVID-19 in the 75+ age group, which represents a slight increase in the number of cases compared to the previous week (+2.4 cases). The 15-29 age group has the highest incidence rate with 44 cases per 100,000 inhabitants.

Quarantine and isolation

For the week from 7 to 13 June, 686 people were in isolation (-18%) and 663 in quarantine (-16% compared to the previous week).

Contaminations

For the 189 new cases, the family circle remains by far the most frequent source of transmission of COVID-19 infections with 45.5%, followed by travel abroad (5.8%) and leisure activities (4.8%). The rate of contamination for which the source is not clearly attributable decreased to 39.1%.

Vaccinations: update on the situation

For the week from 7 to 13 June, 50,111 doses were administered. 17,426 people received a 1st dose and 32,685 received a 2nd dose, bringing the total number of vaccines administered until 15 June to 452,571 (1st and 2nd dose). 197,036 people have a complete vaccination pattern.

The evolution of the variants

For the week of 31 May to 6 June, population sequencing coverage was 45.1%.

Regarding the 324 samples carried out for calendar week 22/2021, the following distribution of variants can be observed:

  • the Alpha variant (UK) B.1.1.7 represents 47.4% of cases, compared to 66% for week 21
  • the Delta variant (Indian) B.1.617.2 represents 30.9% of cases, compared to 15.4% for week 21
  • no new cases of the Beta variant (South African) B.1.351 were detected (3.1% of cases in week 21)
  • no new cases of the Gamma (Brazilian) P.1 were detected (2.1% of cases in week 21)

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

The contamination level of the 13 analysed waste water treatment plants by the LIST (Luxembourg Institute of Science and Technology) during week 23/2021 indicates a constant downward trend over the last few weeks, with some of them showing contamination levels close to or below the detection limits. This result will have to be confirmed by the analyses performed in the coming weeks.
