Geneva, June 11 : The World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus on Wednesday said that more research needs to be done to better understand the extent to which COVID-19 is being spread by people who don’t show symptoms.

“Since early February, we have said that asymptomatic people can transmit COVID-19, but that we need more research to establish the extent of asymptomatic transmission,” the WHO chief said at a virtual press conference from Geneva.

“That research is ongoing, and we’re seeing more and more research being done,” he added.

Though much research has been done, the WHO chief told reporters that “there’s still a lot we don’t know.”

“WHO’s advice will continue to evolve as new information becomes available,” he said.

Tedros stressed that the most critical way to stop transmission is to find, isolate and test people with symptoms, and trace and quarantine their contacts.

“Many countries have succeeded in suppressing transmission and controlling the virus doing exactly this,” Tedros said.
