The LNS has sequenced almost 220 viruses. This method can identify how the virus spread through Luxembourg and trace the regions where it originated.
The majority of cases in the Grand Duchy were linked to Italy and Austria; however, it also circulated heavily through the population.
Tamir Abdelrahman, head of microbiology at LNS, said almost all the analysed cases led back to Italy and Austria, with the 10 first cases in Luxembourg showing links to abroad.
However, at a later date it became evident from analysis of new cases that the virus was rapidly being spread throughout Luxembourg's population.
