Mu variant is in NJ. Experts urge more tracking, testing

Critics say the state should test more widely to track coronavirus variants in New Jersey

Public health experts are keeping a wary eye on the mu variant of the coronavirus. It’s been identified in New Jersey and every other U.S. state, and named a variant of interest by the World Health Organization.

Preliminary lab data suggest that mu isn’t as transmissible as the delta strain but that it might be better at evading vaccines. Scientists say they need more data to assess its threat. Meanwhile, critics say the state should test more widely to track variants in New Jersey, especially since ventilator use in hospitalized cases of COVID-19 is rising.
