There have been eight other cases confirmed in California, plus several individuals who tested positive for the virus while overseas and are currently being retested by the Centers for Disease Control and Prevention. With a conservative estimate of T = 7 days as the average period from case confirmation to death, we would correct the above formula by using February 1 cumulative cases, which were 14,381, in the denominator: Feb. Many of the coronavirus cases have been in the western United States, including eight in California. “The novel coronavirus is a serious public health concern,” Dr. But for some reason children seem to be relatively spared.
