So wrote the Washington Post editorial board Friday:
Many scientists have speculated that the virus leaped from animals, such as bats, to humans, perhaps with an intermediate stop in another animal. This kind of zoonotic spillover has occurred before, such as in the West Africa Ebola outbreak in 2014.
But there is another pathway, also plausible, that must be investigated. That is the possibility of a laboratory accident or leak. It could have involved a virus that was improperly disposed of or perhaps infected a laboratory worker who then passed it to others.
