The WHO and the social action platform Global Citizen have partnered to produce the event.

"We may have to be apart physically for a little while, but we can still come together virtually to enjoy great music. The One World: Together at Home concert represents a powerful show of solidarity against a common threat, "WHO's general director, Dr Tedros Adhanom Ghebreyesus, said.
