Saskatchewan has another four new presumptive cases of COVID-19.

This brings the total number of cases in the province now to 20.

Twelve of these cases are presumptive and eight are confirmed.

Final confirmation is done at the National Microbiology Laboratory in Winnipeg.

A government press release on Thursday says three of the four new cases of novel coronavirus are travel-related and the fourth is a close contact of a previously reported case.

The release also says 19 of the 20 cases are well enough to self-isolate at home and the other case is in hospital for reasons not related to COVID-19.

On Wednesday, Saskatchewan followed suit with B.C., Alberta and Ontario and declared a state of emergency to deal with the ongoing COVID-19 pandemic.

The declaration includes a number of new restrictions.
