President Trump helped popularize the phrase “Wuhan Lab” as the administration promoted the theory that Covid-19 was either created in or escaped from a viral laboratory in Wuhan, rather than emerging as an in-the-wild animal-human transfer, possibly in the Wuhan wet market.
Mentions first emerged in meaningful volumes on television news beginning April 15, peaking the following day and decreasing steadily through April 27. CNN and MSNBC only mentioned the phrase a few times over this period, with Fox News accounting for nearly the totality of mentions.
Mentions of “Wuhan Lab” have begun again on the three channels since May 1, with CNN and MSNBC mentioning it several times, though again Fox News has largely taken the lead on mentions.
