The HSE is urging people to “act sensibly” after a number of social gatherings helped fuel a rise in Covid cases in Sligo and Donegal.
Funerals, wakes, house parties and other indoor gatherings have led to outbreaks in the past two weeks.
The Irish Independent reports that a new pop-up test centre has been established in Buncrana, which currently has the highest infection rate in the country.
Bundoran has also seen a spike in cases.
Dr Anthony Breslin, director of public health for the HSE north-west is urging people to continue to follow public health guidance.
Dr Breslin said he expects the case numbers to continue to rise over the next week.
