“So we’re going to have either a fall/winter wave or a winter wave — a second wave. I can’t exactly tell you when that wave will crest,” said Andrew Noymer, a public health expert and epidemiologist at UC Irvine. “We had this big wave in the summertime, in June/July. everyone remembers that. But that’s not the epidemic. This epidemic is going to have waves — plural. That wave that has now come and gone, that’s not the epidemic gone and over,” Noymer said in a Wednesday phone interview.
