For the week of 1-7 March, the number of people testing positive for Covid-19 decreased by 9.1% from 1,315 to 1,194 people. Similarly, the number of their identified close contacts fell from 3,101 to 2,847 contacts (-9.2%).
The number of PCR tests performed during the week of 1-7 March decreased from 64,376 to 61,564, 4.37% less.
As of 7 March, the number of active infections stood at 2,783 (compared to 2,908 on 28 February) and the number of people 'cured' grew from 51,934 to 53,229. The average age of people diagnosed with Covid-19 has increased to 39.3 years.
24 new deaths, against 12 the previous week, related to Covid-19 are to be deplored. The average age of those who died is 84 years old. 8 people were living in care homes.
In hospitals, there is a clear increase in administrations, with 86 hospitalisations in normal care and 21 hospitalisations in intensive care confirmed for the week of 1-7 March, compared to 68 and 18, respectively, in the previous week.
For the referenced period, the effective reproduction rate (RT eff) increased very slightly from 0.96 to 1.00, while the positivity rate on all the tests carried out (prescriptions, Large Scale Testing, contact tracing) is slightly lower than last week, with 1.94% against 2.04% (average over the week). Note that the positivity rate for tests performed on prescription, therefore for people with symptoms, also decreased with 5.03% against 5.42% for the week before.
The incidence rate is 191 cases per 100,000 inhabitants over 7 days. For the week of 22 February, the incidence rate stood at 210 cases per 100,000 inhabitants over 7 days. Compared to the previous week, the 75 and over age group recorded the largest increase (+ 46%). This increase is due to a large cluster in an accommodation structure for the elderly. The incidence rate remains stable in the 60-74 age group and decreases in all other age groups by (-10% to -20%). The 75-year-old age group now has the highest incidence rate while the 60-74 age group continues to have the lowest incidence rate.
For the week of 1-7 March, 2,703 people were in isolation (+2%) and 3,089 in quarantine (-3% compared to the previous week).
For the 1,194 new cases, the family circle remains the most frequent context of transmission of COVID-19 infections with 42.4%, followed by the aid and care sector (6.4%), work (4.3 %) and leisure (3.1%). The rate of contaminations for which the source is not clearly attributable increased to 37.4%.
8,918 doses were administered in total in the referenced period. 5,493 people received a 1st dose and 3,425 a 2nd.
For the week of 22-28 February, the sequencing coverage of the population was 27%, thus significantly higher than the optimal rate of 10% recommended by ECDC to have a representative sample.
Concerning the representative sampling of 337 samples carried out for week 8/2021, the following distribution can be observed:
- the British UK variant (B.1.1.7) represents 65% of cases;
- the South African variant SA (B.1.351) represents 16% of cases;
- a new case of the Brazilian variant (P.1 or P.2) was detected.
