COVID-19: Review for the week of April 11-17, 2022

In the week of April 11-17, the number of people who tested positive for COVID-19 decreased from 6,172 to 5,403 (-12%).

The number of PCR tests performed during the week of April 11-17 increased from 17,789 to 15,337.

125 people reported a positive rapid antigen (ART) test for the reference week, compared to 153 in the previous week, bringing the number of positive results after ART by a healthcare professional to a total of 2756. Remember that positive rapid antigen tests are not taken into account. When calculating the positivity rate.

As of April 17, the number of active infections decreased to 11,832 from 14,550 on April 10, and the number of people recovered rose to 218,078 (from 209,962). The average age of people diagnosed with COVID-19 is 41.8 years old.

In the week of April 11-17, there are 5 new deaths associated with COVID-19 that we must deplore. The average age of the deceased is 74 years.

In hospitals, 29 new confirmed cases of COVID-19 were admitted to the regular care unit, compared to 28 in the previous week. In intensive care, the number of occupied beds decreased from 4 to 3. 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 0.93 (0.84 the previous week), and the positivity rate in all tests performed (prescriptions, contact tracing) increased from 34.70% to 35.23%.

The infection rate decreased to 851 cases per 100,000 residents within 7 days, compared to 972 cases per 100,000 residents in the previous week.

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

The largest decrease was recorded in the 0-14 age group (-24%), followed by the 45-59 age group (-14%). Please note that in the week from 11.04 to 17.04, there are no approved self-exams in schools. The lowest infection rate was recorded among people aged 0 to 14 years (635 cases per 100,000 population), while the highest infection rate was recorded among people over the age of 75 (1,237 cases per 100,000 population) .

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 6,294 resident cases registered during the week of April 11-17, 2022, only the recalled cases with a result date of 11.04 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. 674 cases recalled on 11.04 were used in the case source description.

The family circle is the most common source (35%), followed by trips abroad (13%), the help and care sector (8%), leisure (7%) and work (6%). The share of unidentified sources decreases (25%).

Vaccinations: update

In the week of April 11-17, a total of 1,207 doses were given: 86 people received a first dose, 176 people received a second dose, 762 people received an additional first dose compared to a full regimen, and 183 people received an additional dose compared to a full schedule, bringing the number The total for vaccines administered as of April 19 is 1,278,410.

472,818 people had a full vaccination schedule, which corresponds to a vaccination rate of 78.6% compared to the immunized population (hence the 5+ population).

COVID-19 vaccination: 4th dose recommended for people over 80 years old

Based on the recommendation of the Supreme Council for Infectious Diseases (CSMI) and agreement with the EMA and ECDC, a fourth dose of the vaccine against COVID-19 can be given to people over 80 years old. The fourth dose is given at intervals of at least 4 months after the booster dose. The vaccine product used for the fourth dose is vaccine mRNA. This booster dose is intended to maintain the high level of protection these people have gained from the vaccine against infection and severe forms of illness and death.

Remember that anyone who is immunocompromised (organ or hematopoietic stem cell transplant, patients undergoing lymphatic chemotherapy or immunosuppressive therapies or those with primary immunodeficiency) or dialysis who are 18 years of age and older can receive a fourth dose of the vaccine. This should be done at least 3 months after the last injection.

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

According to the latest CORONASTEP report developed by LIST (Luxembourg Institute of Science and Technology), the pollution level in 13 wastewater treatment plants analyzed during the fifteenth 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 comparable to those observed last week. Similar trends were observed for the different wastewater treatment plants analyzed, with the signal fixed at a high value for wastewater contamination by SARS-CoV-2.

All CORONASTEP reports are available on the LIST website:

Issued by the Ministry of Health, the Ministry of National Education, Children and Youth, the National Health Laboratory (LNS) and the Luxembourg Institute of Science and Technology (LIST)
