The head of the World Health Organization said on Tuesday China's zero-tolerance COVID-19 policy is not sustainable given what is now known of the virus, in rare public comments by the UN agency on a government's handling of the pandemic.
"We don't think that it is sustainable considering the behavior of the virus and what we now anticipate in the future," WHO Director-General Tedros Adhanom Ghebreyesus told a media briefing.
