Three confirmed cases of the South African variant of COVID-19 have been detected in Northern Ireland.
These are the first confirmed cases in the province.
The risk of transmission is low.
The Department of Health is working closely with the Public Health Agency and the Regional Virology Laboratory in relation to the cases.
Health Minister Robin Swann said the situation was inevitable at some point.
“This development does not mean that this variant is going to become the most prevalent, or the dominant strain in Northern Ireland.
“However, it does underline once again the very real need for continuing caution in relation to COVID-19.
“The best way to stop variants developing or spreading is to keep pushing down infection rates and transmission of the virus in our community,” he said.
The Health Minister emphasised the importance of staying at home, cutting down contacts if you have to go out, avoiding busy indoor settings with poor ventilation, washing hands carefully and often, and wearing a face covering.
All travellers returning to Northern Ireland must self isolate for 10 days from the date of their return.
