There is a strong chance that the novel coronavirus could return in seasonal cycles, a senior US scientist revealed underscoring the urgent need to find a vaccine and effective treatments.
Anthony Fauci, who leads research into infectious diseases at the National Institutes of Health, told a briefing the virus was beginning to take root in the southern hemisphere, where winter is on its way.
“What we’re starting to see now… in southern Africa and in the southern hemisphere countries, is that we’re having cases that are appearing as they go into their winter season,” he said.
“And if, in fact, they have a substantial outbreak, it will be inevitable that we need to be prepared that we’ll get a cycle around the second time.
“It totally emphasizes the need to do what we’re doing in developing a vaccine, testing it quickly and trying to get it ready so that we’ll have a vaccine available for that next cycle.”
On the issue with the vaccine, the scientist said that there are currently two vaccines that have entered human trials — one in the US and one in China — and they could be a year to a year-and-a-half away from deployment.
Treatments are also being investigated — some new drugs and others that have been repurposed, including the antimalarials chloroquine and hydroxychloroquine.
“I know we’ll be successful in putting this down now, but we really need to be prepared for another cycle,” Fauci concluded.
Fauci’s comments suggesting the virus does better in colder weather than it does in hot and humid conditions follows a recent Chinese research paper — still preliminary and awaiting peer-review — that reached the same conclusion.
