The WHO is reiterating its call for countries to "test, test, test" in their fight against the spread of Covid-19.
The organisation has said a vaccine to this coronavirus is at least a year way.
Dr Michael Ryan from the WHO says tackling something like Covid-19 is difficult:
"It takes courage, and it takes determination, but we have to save the lives of people who are very sick and critically unwell.
"But we have to try and suppress the transmission of the virus. And once we suppress transmission, we have to go after the virus.
"We have to take the fight to the virus."
