WHO says earlier statement calling asymptomatic transmission of coronavirus ‘very rare’ was a ‘misunderstanding’
A comment by a WHO official on Monday — calling such asymptomatic transmissions “very rare” — touched off a furious scientific debate over the unresolved question and attracted widespread criticism of the organization.
Less than 24 hours later, WHO convened a special news conference to walk back its comments, stressing that much remains unknown. But the comment from Monday had already spread widely and been seized upon by conservatives and others to bolster arguments that people do not need to wear masks or maintain social distancing precautions.The episode sparked criticism of WHO’s public health messaging and highlighted just how fraught and easily politicized such work remains months into the pandemic.
“I wasn’t stating a policy of WHO or anything like that,” she said. “We do know that some people who are asymptomatic, or some people who do not have symptoms, can transmit the virus on.” It was not the “intent of WHO to say there is a new or different policy," added Mike Ryan, head of emergency programs for WHO. “There is still too much unknown about this virus and still too much unknown about its transmission dynamics.”While asymptomatic transmission does occur, no one knows for sure how frequently that happens. Studies and models have suggested many of those infected never show symptoms. And it remains an open question whether they are a large force driving transmission.
Further complicating matters is the fact that in some people, symptoms are so mild — or manifest themselves in less expected ways such as diarrhea or muscle aches, instead of the classic fever and cough — that people aren’t aware of them until later on.“It’s a mess. I don’t know why they would say asymptomatic transmission is very rare when the truth is we simply don’t know how frequent it is," said Eric Topol, a professor of molecular medicine at Scripps Research.
