According to Reporter.lu, fifteen residents are thought to have contracted the virus.
Management for the nursing home "Les Parcs du 3e Âge" confirmed this information as a resident was hospitalised on Thursday morning.
Two staff members have also been infected.
However, management stated that the staff were well protected against the virus, with all the necessary protective equipment - overalls, glasses, masks and gloves - which the establishment has obtained itself.
The Ministry of Health immediately promised to assist the staff.
For the moment, the infected residents have been isolated on one floor and are being taken care of by nursing staff who work in shifts of six to eight people.
The first case of Covid-19 infection at the retirement home was detected on 18 March.
The woman's passing marks the ninth death linked to the coronavirus in Luxembourg.
On Thursday, the government confirmed a total of 1,453 cases in the Grand Duchy, an increase of 120 compared to the day before.
