U.S. ‘keeping a very close eye’ on mu variant--Dr. Fauci

A coronavirus variant known as mu — which was designated by the World Health Organization as a “variant of interest” earlier this week — is not an “immediate threat” to the United States, according to Anthony S. Fauci, the country’s top infectious-disease expert.

Fauci told a news briefing Thursday that the variant was “not at all even close to being dominant,” as the delta variant remains the cause of over 99 percent of cases in the country. But he added, “We’re keeping a very close eye on it.”
