Covid: Which Welsh universities have had cases?
The situation for Welsh universities dealing with rising coronavirus cases is "manageable", according to the woman representing the sector.
Universities Wales chairwoman Prof Julie Lydon said a spike in cases among students was to be expected.
Her assessment came as six out of eight Welsh universities told BBC Wales they had seen confirmed cases of Covid-19.
Responding to calls for refunds, Prof Lydon said students had been made aware of the potential for disruption.
On Monday, Aberystwyth University suspended in-person teaching after a spike in cases, and Swansea University announced last week that 12 students had tested positive for coronavirus.
The BBC asked universities in Wales whether they had seen any coronavirus cases. The following universities said they had.
