Much is still a mystery to health experts in the path to fight against COVID-19

“There’s just a remarkable amount of diversity from state to state in what the epidemic is playing out like,” said Dr. Andrew Noymer, epidemiologist, demographer, [and associate professor of population health and disease prevention] at UC Irvine, on Thursday’s Ask an Expert with KCBS Radio’s Holly Quan and Dan Mitchinson. “We don’t fully understand all of those differences,” he said. Which is quite different from the past, such as the 1918 flu epidemic.
