COVID-19: Review for the week of April 4-10, 2022

In the week of April 4-10, the number of people who tested positive for COVID-19 decreased from 8,110 to 6,172 (-24%).

The number of PCR tests performed during the week of April 4-10 increased from 22,274 to 17,789.

153 people reported a positive rapid antigen (ART) test for the reference week, compared to 86 in the previous week, bringing the number of positive results after ART by a healthcare professional to a total of 2,631. Remember that positive rapid antigen tests are not taken into account. When calculating the positivity rate.

As of April 10, the number of active infections decreased to 14,537 from 18,120 on April 3, and the number of people recovered increased to 209,975 (from 200,229). The average age of people diagnosed with COVID-19 is 41.1 years.

During the week of April 4-10, there are 9 new deaths related to COVID-19 that we have to regret. The average age of the deceased is 84 years.

In hospitals, 28 new confirmed cases of COVID-19 were admitted to the regular care unit, compared to 24 in the previous week. In intensive care, the number of occupied beds increased from 3 to 4. The average age of patients in the hospital is 59 years.

Positivity rate and infection rate

For the reference period, the effective reproduction rate (RT eff) increased to 0.83 (0.79 the previous week), and the positivity rate in all tests performed (prescriptions, contact tracing) increased from 36.41% to 34.70%.

The infection rate decreased to 972 cases per 100,000 residents within 7 days, compared to 1278 cases per 100,000 residents in the previous week.

Re-infection as well as school-approved self-tests were included in the calculation of infection rates. Compared to the previous week, the incidence is increasing in all age groups.

The largest decrease was recorded in the 0-14 age group (-57%), followed by the 15-29 age group (-32%). Note that for the week of April 4-10, school-approved self-tests account for 0.1% of cases among 0-14-year-olds and no cases among 15-29-year-olds.

The lowest infection rate was recorded between 0-14 years (835 cases per 100,000 residents), while the highest rate was recorded between 30-44 years (1408 cases per 100,000 residents).

radioactive contamination

As the number of cases continues to rise, it is difficult to call all the cases of the week and thus determine the possible source of the contamination. Of the 7,187 resident cases registered in the week of April 4-10, only those whose results date were April 4 and April 8 were called. Cases were reviewed and the source identified.

For the other days of the week, it was decided to review all cases of people over the age of 60 as well as all residents and workers in nursing homes. 2,527 status calls were reviewed and attribution identified.

Family circle is the most common source (31.1%) followed by leisure (7.0%), travel abroad (6.2%) and work (6.2%), then education (4.6%). – Decrease in the share of unidentified sources (25.6%).

Vaccinations: update

In the week of April 4-10, a total of 1,339 doses were administered. 112 subjects received a first dose, 252 received a second dose, 819 subjects received a first supplemental dose compared to the full regimen and 156 subjects received a second supplementary dose compared to the full regimen, bringing the total number of vaccines administered as of April 12 to 1,277,243.

472599 people had a full vaccination schedule, which corresponds to a vaccination rate of 78.6% compared to the immunized population (hence the 5+ population).

Wastewater monitoring in Luxembourg in the context of SARS-CoV-2

According to the latest CORONASTEP report developed by LIST (Luxembourg Institute for Science and Technology), the pollution level in 13 wastewater treatment plants analyzed during the 14th week of 2022 shows a very high prevalence of SARS-CoV-2 in wastewater in over national level. The flows of SARS-CoV-2 measured this week are very similar to those observed at the end of last week. Similar trends were observed for the different wastewater treatment plants analyzed, with the sewage contamination by SARS-CoV-2 stabilizing at a high level.

All CORONASTEP reports are available on the LIST website: https://www.list.lu/en/covid-19/coronastep/
