People across Northern Ireland have been reminded to stay at home this Easter bank holiday weekend.
Assistant Chief Constable Alan Todd urged people to use their common sense and only leave the house if absolutely necessary.
NI's Chief Scientific Adviser Prof Ian Young said now was the wrong time to relax, with hints social distancing was "beginning to have an effect".
The total number of NI deaths in the coronavirus outbreak has reached 78.
On Wednesday it was confirmed another five people had died in the past 24 hours, while there were anther 84 cases - a total of 1,339.
There have been 7,097 coronavirus hospital deaths across the UK and 235 deaths in the Republic of Ireland.
Prof Ian Young told the BBC's Good Morning Ulster programme people needed to stick to the restrictions.
"We're just beginning to see that perhaps this is having benefit, we have the Easter weekend coming up, maybe with some good weather, people may be tempted to go out and about a bit more," he said.
"But this is just the wrong time to do it. We need to hang on and continue to adhere as strictly as we can to the current measures."
PSNI ACC Alan Todd said it was important to remember travel was not allowed for the purpose of exercise and reminded the public of the restrictions in place:
- People are allowed to leave home in order to exercise
- To travel for work or to provide voluntary or charitable services but only when that is not possible from home
- To travel for essential matters, which include medical assistance, obtaining basic necessities such as food and medical supplies, provide care or assistance to a vulnerable person, donate blood or to attend a funeral of a member of your household or close family member.
The PSNI, Translink and Causeway Coast and Glens Council have issued a joint statement, warning people not to be tempted to flock to the north coast this weekend.
Police in the Republic of Ireland have been given new powers to restrict people's movements and gatherings for the next five days under emergency legislation.
There will be 50 checkpoints on main roads across the country from Wednesday to discourage people from travelling over Easter.
Garda Commissioner Drew Harris said if people were currently staying in their holiday homes that was now considered their place of residence and they should not leave during the current restrictions.
The penalties for those not complying with the rules include fines of up to €2,500 (£2,200) and up to six months in prison.
A Garda (Irish police) spokesperson added "We will liaise with our colleagues in the PSNI to deal with any issues that arise around cross border traffic, and would appeal to the public in Northern Ireland to fully comply with the regulations announced today.
In the UK, Health Secretary Matt Hancock has said it was an instruction and "not a request" to stay home this weekend.
Meanwhile, Northern Ireland is to receive more ventilators and respiratory equipment as part of a UK government scheme.
For patients with the worst effects of the infection, a ventilator offers the best chance of survival.
The machines will arrive in phased deliveries, but the Department of Health says it is unable to give precise times because of competing global demands.
It says there is currently sufficient capacity, equipment and oxygen to provide critical care in Northern Ireland.
There are 197 mechanical ventilators available here and the department estimates it may need up to 400 to meet both coronavirus and non-coronavirus critical care in the coming weeks.
Another 500 respiratory devices to support patients before or after critical care are also on order.
