California health officials on Monday released new information about four residents who were exposed to the Hantavirus and are now being monitored, all of whom are currently healthy and not showing symptoms. The two people being monitored in California are not currently showing symptoms, but health officials said it can take up to 42 days for symptoms to appear.
