The full report on a study into virus origin will be released in the coming days, according to a World Health Organization official who led the international team that investigated the origins of COVID-19. 

"The content is now complete, and, frankly speaking, I expect that in the next few days that whole process will be completed, and we'll be able to release it publicly," said Peter Ben Embarek, head of the WHO international team during the trip to Wuhan in February.
