The R rate – a crucial measure of how quickly coronavirus is spreading – has jumped in Northern Ireland.
The devolved government’s health department said it rose from between 0.5 to 1 last week, to between 0.8 and 1.8.
The number represents how many people someone with COVID-19 passes the disease on to.
Scientists caution that as case numbers drop, the figure will shift with “volatility” and be “heavily influenced by small local clusters”.
“Community transmission remains low in Northern Ireland,” the devolved government said on Thursday.
“Although it is important to note that the number of positive tests per day has increased threefold from early July.”
