It’s highly contagious, more dangerous, and circling the globe. The new Delta variant of the coronavirus — which originated in India — is now spreading in New Jersey, where 30 cases have been identified. “We’re already seeing in the UK that the case rates are higher in schoolchildren than any other group,” said epidemiologist Dr. Stephanie Silvera of Montclair State University. And infection by this variant generally makes patients sicker than the original virus.
Vaccines do work against the Delta variant although one shot of a two-dose vaccine isn’t enough; people need to get the second dose to gain at least 88% protection.
