The novel coronavirus may never go away and populations around the world will have to learn to live with it, the World Health Organization (WHO) warned on Wednesday.

As some countries around the world begin gradually easing lockdown restrictions imposed in a bid to stop the novel coronavirus from spreading, the WHO said it may never be wiped out entirely. 

The virus  has infected more than 4.2 million people around the world and killed nearly 300,000.

"We have a new virus entering the human population for the first time and therefore it is very hard to predict when we will prevail over it," said Michael Ryan, the WHO's emergencies director.

"This virus may become just another endemic virus in our communities and this virus may never go away," he told a virtual press conference in Geneva.

"HIV has not gone away - but we have come to terms with the virus."

More than half of humanity has been put under some form of lockdown since the coronavirus crisis began.

But the WHO warned there was no way to guarantee that easing the restrictions would not trigger a second wave of infections.

"Many countries would like to get out of the different measures," said WHO chief Tedros Adhanom Ghebreyesus in a statement.

"But our recommendation is still the alert at any country should be at the highest level possible."

Ryan added that there was a "long, long way to go" on the path to returning to normal, insisting that countries would have to stay on this track.

"There is some magical thinking going on that lockdowns work perfectly and that unlocking lockdowns will go great. 

Both are fraught with dangers," the Irish epidemiologist said.

Ryan also condemned attacks on healthcare workers that were linked to the pandemic, saying more than 35 of "quite serious" such incidents were recorded in April alone in 11 countries.

He said that the attacks were often over-reactions from ill-informed communities - while others were more sinister.

"COVID-19 is bringing out the best in us, but it's also bringing out some of the worst," he said.

"People feel empowered to take out their frustrations on individuals who are purely trying to help."

"These are senseless acts of violence and discrimination that must be resisted."

But he insisted that finding a way to conquer the virus was a chance for humanity to take a major step forward by finding a vaccine and making it widely accessible.

"It's a massive opportunity for the world," Ryan said.
