Covid-19 Overview Luxembourg (including non-residents)
Daily situation and changes since the previous update
Weekly indicators
Daily Diagnosed Cases and Deaths

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 assumes the data follows a Negative Binomial distribution and fits a cubic B-Spline to the mean parameter with knots every Wednesday and adjustment for under/over-reporting on weekends and weekdays respectively. The area under the curve is maintained close to total cases. 90% centred interval of the mean shown.)
Gray area marks days without sufficient data to reflect the current state of the pandemic in Luxembourg.

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

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.

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 25 tests are shown.
Proportion of total new cases/tests by residency

Proportion of daily new cases / tests by residency. 15 Day centred moving average.
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 perscription 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).

Hospitalisations
Similar to testing, data on hospitalisations was only sparse before April 3. On March 27 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. This includes patients transferred to outside Luxembourg to alleviate hospitals in the originating regions.
The revised figures used here for both categories of patients are questionably low before March 22 and do not agree with numbers reported at the time.
Cases on log and linear scale


Cumulative Diagnosed Cases and Deaths though April 20
Showing cumulative numbers of diagnosed cases on a semi-log plot allows one to see how fast the virus is spreading in the population as constant a growth (or doubling time) forms a straight line in this graph.
The effects of measures to reduce the spread are clearly visible albeit delayed by the incubation period of the disease. This graph has been cut off at April 20 as the pandemic clearly wasn't exponential any more.

A marks the announcement of initial measures to protect vulnerable persons (), B the begin of general restrictions on movement and physical social interactions ().
Footnotes
[a] The data wasn't/isn't reported daily, showing an increase would be misleading.
[b] Includes all cases. For cases from residents only subtract about one fifth. Based on 626108 residents.
[c] Includes all tests. Based on 626108 residents.
[d] Corrections to daily new cases and tests have generally been negligible the last few weeks. If this changes this could bias the indicator downwards and the window used to calculate will need be shifted backwards by a few days.
