A NPHET member's warning the country's reopening will be delayed if people socialise too much in the coming weeks.
Dr Mary Favier is concerned about the scenes over the weekend, when people gathered in large groups in the hot weather.
She says there's a danger of a spike in cases later this week as a result.
Dr Favier says it's vital to avoid a repeat of the sharp rise in cases after Christmas - and a fourth wave.
"When you come to count your close contacts after the weekends we're seeing that they're in the 20s or 30s, so we only need on covid case there and we have a super spreader event and then the numbers take off.
"While we're not in a situation like before Christmas in terms of indoor activity, but potentially we're not far off it if we're not careful.
"If the numbers do rise very rapidly unfortunately the reopening will be delayed and we could be back to square one."
