WHO warns coronavirus may be here to stay, in absence of vaccine, amid cluster outbreaks

A top World Health Organization official says the new coronavirus may never completely go away, amid the absence of a vaccine and the impossibility of no human contact.

The WHO’s Dr. Michael Ryan said Wednesday that humans worldwide might need years to build up sufficient levels of immunity in the absence of a vaccine, amid reports of a second wave on infections worldwide, including in Wuhan, China, where the virus started, and as officials easy health-safety restrictions to restart their economies.

"This virus may never go away," Ryan said, according to the Associated Press. "I think it's important to put this on the table." 

Ryan pointed out that other novel diseases like HIV still exist but that therapies have made them far less deadly.
