For the week of 1-7 February, the number of people testing positive for Covid-19 increased from 999 to 1,140 people (+14%) and the number of their identified close contacts increased from 2,774 to 4,067 (+47%).
61,488 PCR tests were carried out, up from 51,337.
As of 7 February, the number of active infections stood at 2,465 (compared to 2,276 on 31 January) and the number of people ‘cured’ has increased from 47,878 to 48,816. 13 new deaths, against 14 the previous week, related to COVID-19 are to be deplored. The average age of the deceased has not changed (86 years).
The average age of people diagnosed with COVID-19 has further declined to 34.1 years.
In hospitals, the situation remains relatively stable, with 50 hospitalisations in normal care and 13 hospitalisations in intensive care, against 55 and 13, respectively.
Last week, the effective reproduction rate (RT eff) decreased slightly from 1.10% to 1.05%. A decrease can also be observed with regard to the positivity rate on all the tests carried out (prescriptions, Large Scale Testing) with 1.85% against 1.95% last week (average over the week). The positivity rate for tests carried out on prescription also dropped from 5.19% to 4.83%.
The incidence rate is 182 cases per 100,000 inhabitants over 7 days, compared to 160 cases in the week before.
The incidence rate continues to increase among children aged 0-14 (+ 46%), among 30-44 years (+29), and among people aged 60-74 (+ 41%). The 10-14 age group has the highest incidence rate while the 60-74 age group continues to have an incidence almost half that of the rest of the population.
For the week of February 1 to 7, 2,155 people were in isolation (+ 18%) and 4,295 in quarantine (+ 21% compared to the previous week).
For the 1,140 new cases, the family circle remains the most frequent context of transmission of Covid-19 infections with 38.6%, followed by education (14%) and work (4%). The rate of contamination for which the source is not clearly attributable is 32.5%.
Since the British variant B.1.1.7. began to circulate in Luxembourg on 19 December 2020, 860 samples were sequenced by the National Health Laboratory (LNS). Among these samples, the LNS demonstrated the UK variant (B.1.1.7) in 114 people (+18 compared to the previous week). The South African variant SA (B.1.351), whose sequencing started on 11 January, has been detected so far in 14 people (+10).
This data is not representative, however, as not all sequencing is targeted and there is a 7-10 day delay in obtaining genotyping results. The Directorate of Health and the National Health Laboratory are in the process of putting in place the means required to have a representative sampling of the general population based on samples from different regions and age categories with the help medical analysis laboratories.
For the week of 1-7 February, 5,198 doses were administered in total. 3,190 people received a 1st dose. The number of people who received a 2nd dose increased significantly to 2,008 (compared to 439 the previous week).
