Mr Lee made a comparability to dengue fever, which he famous was managed by means of “public well being measures and private precautions”.
There may be precedent for epidemics to ultimately change into endemic, stated Professor Paul Tambyah, president of the Asia Pacific Society of Medical Microbiology and An infection, who pointed to a number of examples.
“It occurred most just lately with H1N1 Influenza A 2009, which grew to become endemic inside a year-and-a-half,” he stated, pointing additionally to different situations in 1957 and 1968.
COVID-19 may change into “identical to one of many ‘frequent chilly’ coronaviruses”, stated Prof Tambyah, with the aged being the primary concern.
“That’s what many individuals consider occurred with OC43, one in all right this moment’s frequent chilly coronaviruses which is believed to have precipitated the ‘Russian Flu’ pandemic of the late nineteenth century,” he stated.
Turning into endemic means COVID-19 will not be going to “go away”, stated Professor Dale Fisher, who chairs the World Well being Group’s International Outbreak Alert and Response Community.

COVID-19 may flow into and mutate in methods much like influenza, he stated, noting that in temperate climates it may change into a seasonal illness.
Nevertheless, Prof Fisher burdened that this doesn’t imply that sceptics who stated that COVID-19 was no worse than the flu have been right.
“Anybody that is thought COVID is just like the flu, I believe they have been confirmed to be flawed in some ways, not least of which is the severity (of COVID-19),” he stated.
Whereas most of those that contracted the illness solely skilled delicate signs, thousands and thousands have died, he identified.
Greater than 3.5 million folks have died from COVID-19 for the reason that pandemic started final 12 months, in comparison with the estimated 290,000 to 650,000 who die from influenza yearly.

“If we take our foot off the brakes now, then we’re going to have an explosive state of affairs,” he stated, noting lower than 40 per cent of Singapore’s inhabitants have had not less than one jab of the COVID-19 vaccine.
It’s exhausting to say when COVID-19 would possibly change into endemic globally, stated Prof Tambyah, although he famous that one estimate suggests it’d take three or 4 years.
“Endemic residing will occur in Singapore once we obtain a excessive vaccination charge of about 70 to 90 per cent of the inhabitants and when unlinked circumstances don’t overwhelm our contact tracing capabilities,” stated Dr Leong.
“Care of COVID-19 sufferers will enhance with higher medical applied sciences, and maybe oral antiviral remedies and extremely efficient, broadly neutralising, monoclonal antibodies that may kill the virus,” he added.
Nonetheless, COVID-19 changing into endemic doesn’t rule out the opportunity of future pandemics, specialists say.
“So long as we proceed to encroach onto the territory of untamed animals and do all types of experiments in numerous laboratories, there’s at all times a danger of one other coronavirus breakout,” stated Prof Tambyah.
There’s a “very excessive likelihood” of a novel influenza pandemic within the subsequent few years, he added.
“There has not been very a lot influenza worldwide and in reality, the final case of influenza detected by surveillance in Singapore was greater than a 12 months in the past,” he stated, describing influenza as “promiscuous” and capable of dwell in quite a lot of animals starting from geese to seals.
“I do not suppose we purchased a breather, nature does what it does,” stated Prof Fisher.
“May there be a brand new pressure of flu that’s (much like COVID-19) subsequent 12 months? That is potential.”
