"If anyone is tempted to associate 'lab leak' with xenophobia or anti-Chinese sentiment, please remember the WIV lab was in partnership with the U.S. NIH ..."

Thank you. I'm curious ... how many virology labs, like this one, are extant in the world and how many study coronaviruses as they did ?

Is it tens of thousands of virology labs like this one and hundreds that study coronaviruses ?

Or is it hundreds of virology labs like this one and a handful study coronaviruses ?
