Covid-19 Overview Luxembourg (residents only)

Recent Changes
  • Vaccination Policy

    Only 25% of AstraZeneca doses are kept back for a second dose starting . This is now reflected in the number of vaccines available for use.

Numbers shown above are the latest available figures, these generally apply to the previous day (e.g. figures reported on Monday afternoon reference Sunday). The change represents the difference from what was reported the day before (e.g. the increase in tests shown above is not necessarily the number of tests conducted on that day, but might include increases to the number of tests for multiple days). The date shown indicates the latest available data point.

The graphs below use revised data and reflect what happened on / has been referenced to that day and not necessarily what was reported on that date.

Daily Diagnosed Cases and Deaths

daily new diagnosed cases

Daily new diagnosed cases. The smoothed curve should not be interpreted as a curve of "true" new cases nor should it be used as a prediction at the end of the time series.

(The smoothing model fits a cubic B-Spline to the mean with a log-link and a Negative Binomial likelihood to account for overdispersion. Spline knots are placed weekly, adjustment for under/over-reporting by day of week. The area under the curve is maintained close to total cases. Mean and 90% centred credible interval of the mean shown.)

daily new deaths

Daily new deaths. Earliest death was reported on 13 March.

Reproduction Number

Because of the reduced testing between 24 December 2020 and 2 January 2021 the estimates for the reproduction number will be biased down, then up once testing goes back to normal levels.

effective reproduction number

Effective reproduction number from infered infections from all detected cases. 95% centred credible interval shown.

Testing

Tests performed

daily tests

Daily number of tests performed. It is unclear if these are referenced to the date the samples were taken, analysed or reported. On March 26 about 5500 tests were added, these are likely from earlier days.

Daily number of tests performed last 12 weeks.

Positivity

daily percentage of positive tests

Using daily new diagnosed cases and tests conducted a ratio of positive tests can be approximated. Not all diagnosed cases necessarily come from positive tests, the number of tests conducted and cases don't necessarily refer to the same day. Only days with more than 50 tests are shown.

Positivity by Category

daily percentage of positive tests last 12 weeks

Test positivity during the last 12 weeks.

Dots represent daily positivity, line segments weekly averages. For Fridays & Saturdays, as well as days preceding public holidays, there is no breakdown by test category available. Weekly averages are usually reported on Wednesday of the following week.

Single day outliers might be cut off to increase legibility. e.g. 21 February 2021 had 71% (17 of 24) positivity among tracing tests.

Vaccination

Persons vaccinated

Unlike total doses administered, total first doses administered gives a clearer picture about the progression and efficiency of the vaccination relative to the available stock factoring in how many doses are held back to secure the administration of a second dose.

Multi-dose vaccines are counted once, except for AstraZeneca for which only 25% — instead of 50% — are held back starting from . As it's unclear how exactly this policy is implemented the chart shows 75% of all AZ doses delivered starting from ).

Cumulative number of persons vaccinated (includes non-residents) and available vaccine stock.

Proportion of available stock used

Doses administered

As a second dose is held back for most vaccines the % of doses used can't reach 100% until vaccination is complete.

Total number of doses administered and received

Cumulative number of doses administered and received. Multi-dose vaccines are counted multiple times.

New Cases and Tests by Category

Since the MoH publishes additional data on positive and total tests broken down by how/where the person was tested. Data on cases and tests from the LST scheme is available from to , but it is unclear how reliable these figures are.

Tests are categorized into four groups: on prescription by a doctor ("Diagnostic"), as part of contact tracing from previously detected cases ("Tracing"), as part of the Large Scale Testing scheme including entry/exit tests ("LST") and via a free voluntary test at the airport ("Airport"). "Unknown" includes tests from dates where no breakdown is available, or if the number of total tests is greater than the sum of all categories (for example if the number of tests is corrected upwards on a later date).

Age Distribution of Active Cases

A breakdown of active cases per 5-year group is only available since mid May, and allows for a view on what age group is currently the impacted the most.

It's important to remember that age is not distributed evenly in the whole population (cf. Figure 16). Some groups also have more contacts on average and thus more opportunities to get infected.

Data on ages of all tested persons by day is not available, nor is there any information on the distribution of diagnosed cases by day.

Proportion of active cases by 10-year age group. Black line marks date where the underlying population supposedly changed, given the data it is questionable whether the population was changed on this specific date.

Age distribution of currently active cases compared to the whole population (as of April 2020).

Hospitalisations

Similar to testing, data on hospitalisations was only sparse before 3 April. On 27 March the capacity of hospitals in Luxembourg was 2354 beds with an additional 230 available if needed, 119 beds for intensive care patients with 80 further beds available if needed. The number of hospitalised patients for reasons other than COVID-19 is unknown.

Current number of patients in hospital and in intensive care respectively.

The revised figures used here for both categories of patients are questionably low before 22 March and do not agree with numbers reported at the time.

These numbers includes patients those temporarily transferred to Luxembourg to alleviate hospitals in the originating regions in March/April, but not those that are suspected to have COVID-19, or those that have tested positive for SARS-CoV-2 but are hospitalised for different reasons.

The number of patients suspected to have COVID-19 is not published on weekends/holidays and the total number can therefore decrease suddenly on these days and is thus not included here.

Footnotes

[a] The data wasn't/isn't reported daily, showing an increase would be misleading.

[b] Includes cases from residents only. Based on 626108 residents.

[c] Includes tests from residents only. Based on 626108 residents.

[d] Corrections to daily new cases and tests have generally been negligible. If this changes it could bias the indicator downwards and the window used to calculate will need be shifted backwards by a few days.
