The victim was a 90-year-old lady, according to the Belgian media sources.
The patient “died despite the quality medical service provided” by the Iris-Sud Clinic in Brussels, de Block told the press.
The ministers expressed their condolences to the family of the victim and praised “the tireless, calm and professional work” of medical experts.
To prevent the spread of the virus, Belgium banned on Tuesday events hosting more than 1,000 people.
In total, 295 coronavirus cases have been reported in Belgium so far.
Coronavirus, officially known also COVID-19, was first detected last December in Wuhan, China.
The virus has spread to six continents and more than 100 countries.
