Northern Ireland's Department of Health said it is not looking at a localised lockdown in Limavady, Co Derry at this time. A Covid-19 cluster has been identified following a social gathering at a house in the Limavady area.
Yesterday Northern Ireland's Health Minister, Robin Swann said they had long anticipated and warned that clusters will happen.
The Public Health Agency has set up a mobile testing unit in the town to test and contact trace people to prevent the spread of the disease.
The PHA said it is too early to provide figures around the uptake of testing at this site as the unit only arrived at the the North West Regional College today.
