U.K. Covid Surge Sparks Call for Probe Into Delta Plus Mutation.

(Bloomberg) -- Former U.S. Food and Drug Administration Commissioner Scott Gottlieb called for "urgent research" into a mutation of the delta variant -- known as delta plus -- following a surge in Covid-19 cases in the U.K. "We need urgent research to figure out if this delta plus is more transmissible, has partial immune evasion", Gottlieb said in a tweet. A German paper out earlier this month found while both delta and delta plus infect lung cells more efficiently than the original coronavirus strain, delta plus doesn't appear to be significantly more dangerous than delta.
