The University Hospital of Leuven (UZ Leuven) refused a shipment of 3,000 masks from China because the equipment was not reliable enough, Herman Devrieze, head of the prevention department at UZ Leuven, told local TV station ROBtv on Sunday evening.

The masks did not fit properly around the nose and the protection of the filters left something to be desired, according to reports.

Devrieze took the opportunity to call on all involved bodies to be very vigilant with regard to the material offered and, even if the need is very high, not to bring in everything that is offered.
