Ravalli County Reduces Quarantine Times Ravalli County Public Health has reduced quarantine times for many who have tested positive for COVID-19, according to Director Tiffany Webber. In her April 12 news release, Webber said that County Health Officer Dr. Carol Calderwood has approved adoption of two reduced times provided by the Centers for Disease Control (CDC). Of course, the original 14-day quarantine is still the best way to stop the spread of the disease. But, Webber and Calderwood say, since the COVID numbers have remained steady in Ravalli County, the two reduced quarantine times are now offered. From the news release:
