More than one in five new confirmed Covid-19 cases in the Republic of Ireland are linked with travel.
The Health Protection Surveillance Centre has recorded 270 cases over the past two weeks.
And 21% of these new infections have been associated with foreign travel.
The new statistic revealed by the Department of Health means there are around 60 active travel-related cases in the Republic.
It comes as no further coronavirus deaths and six new infections have been announced.
Speaking on Monday evening, Dr Ronan Glynn, Acting Chief Medical Officer, Department of Health, said: “We are now seeing outbreaks of the virus in a range of work settings, including in construction, in fast food outlets and in supermarkets.
“We can’t underestimate how quickly clusters develop. We have come so far together, but we need to stay vigilant to prevent a resurgence across the whole country in the coming weeks.
"Many workplaces have introduced the new regimes and safety measures necessary to reopen their businesses.
"I would remind all employers that the workplace and most particularly, shops, services and supermarkets, are the new front line, we are asking you to do everything you can to put the safety of your staff and customers first.
“With the increase in outbreaks in our communities, I would urge everyone to wear face coverings in healthcare settings and when shopping, including in the supermarket and other indoor retail services.”
Of the cases registered in the past two weeks, 57% of these were in women with men representing 43%.
The median age of the new infections were 34, with nearly 70% of them in people under the age of 45.
Rachel Kenna, Chief Nursing Officer, Department of Health, said: “Our healthcare workers have been at the front line since March and they deserve our best efforts to continue to minimise the spread of this virus.
“The impact of any increase in cases will be hard on healthcare workers, who have already given so much to keep us safe this year.
“Let’s reward their dedicated and unwavering service by holding firm on COVID-19.”
