At that level, lab workers are usually dealing with pathogens that either cause mild disease in humans or which don’t typically spread through small particles that linger in the air. Researchers at that level don’t necessarily wear masks.
> The Wuhan CDC lab tested all of its staff for Covid-19 antibodies, it told the WHO in February. All staff tested negative, except one who tested positive, it said. That person was infected “due to family cluster transmission,” the WHO-led team’s report’s annex says.
> But Dr. Ben Embarek is the first to so explicitly question the team’s conclusion, published in a joint report with Chinese counterparts, that a lab accident was an “extremely unlikely” hypothesis.

> The lab hadn’t published any work with bats since 2013, he said.
> “As far as we understand, they work mostly with parasites, not as much with viruses, so they have worked on parasites from bats.”
Yet, after fighting to label the lab leak theory “unlikely”, he throws a bone to the conspiracy theorists:
> “It’s also possible that someone is trying to hide something,” he added. “Who knows?”
