It would be reckless not to prepare for a second wave of Covid-19, a leading GP has said.
Dr George O'Neill warned another peak of the virus was likely.
It came after Northern Ireland's chief scientific adviser said the region must be braced for a second wave, most likely in the autumn or early winter.
Professor Ian Young said there is a "high likelihood" of a new wave, and others in the future.
"I do not think it is inevitable, but I think it is something that is extremely sensible to plan for," he told BBC Radio Foyle.
"And the most we can do to try and stop it is to stick to the restrictions in place, to remember the hand washing, to remember the respiratory hygiene, wear a mask that has been recommended on public transport and in shops, and being careful to keep our distance as much as we can," the government adviser said.
"I think that everybody is concerned about the possibility of a second wave, or more than one additional wave, of this virus."
Prof Young said the virus would be part of life for the foreseeable future.
He added: "It is going to remain with us for a long time until we get a significant level of the population with immunity, which probably means that at least 70 to 80% of the population need to be immune either because they have been infected, have recovered and retain immunity, or because there is a successful vaccine."
Dr O'Neill, joint chair of the West Belfast GP Federation, echoed the scientific adviser's view that it will be prudent to plan for a second wave.
"No one knows if there will be a second wave, but history tells us there is a probability," Dr O'Neill said, citing the Spanish Flu of 1918, which first appeared early that year then returned in a "brutal" way in the autumn.
"If it happens, it will likely be in the winter during the 'normal" flu season, Dr O'Neill said, adding: "It will be prudent to make preparations for the possibility."
He added: "Nobody knows for certain, but this is a novel virus and strange things are happening almost every day.
"It is best to be prepared and would be folly not."
Professor Young predicted that there will be a lower risk in the summer time as it is known the virus survives less well in the sunlight and outdoors.
If exposed to ultraviolet light, the virus is destroyed within minutes, but can survive for between 48 and 72 hours on hard surfaces indoors, research shows.
The scientific adviser added: "There is still risk during that time and as we get into the autumn and winter where people are spending more time indoors, they are closer together, there is not so much sunlight and we have the normal flu season then all of those things add together and certainly increases the risk... and that is definitely something people are thinking about and considering in planning."
The advice at this stage is against indoor visits of family members, but the government is allowing family members to meet outdoors.
"The indoor visits are a significantly higher level of risk than the outdoor visits, which we are encouraging and the Executive has permitted at the moment," Professor Young said.
"In terms of indoor activities or business, visits to close family members while maintaining social distancing and being very careful with cleaning surfaces are at the low risk of the spectrum... but right now, they are a step too far," the adviser said, adding that he is urging people to keep those visits outdoors.
Professor Young added that his team and others are working on the basis of the R, or reproduction number.
It currently sits at approximately 0.8, which reveals how many people are infected by any one individual.
"We need to make sure that R stays below one and for us to be certain about that typically takes about two or three weeks (after each stage)," he said.
The R number has not changed in any significant way over the last number of days.
"When the R number is under one, then the epidemic is under control," Prof Young added,
The R number is calculated by crunching data from several weeks, including the number of new cases per day, patients admitted to hospital, those who need critical care treatment, outbreaks in care homes and the number of deaths.
