Briggs told the board the number of positive cases has been increasing. As of Monday, the county’s total of confirmed positive cases had grown to 1147.  

But Briggs also told the board he suspects the number of county residents who have been exposed to the virus is pretty low, possibly less than 5-percent. Briggs says it appears about 12-percent of local cases have been asymptomatic.  

He also says Olmsted County’s number of hospitalizations remains low and the local health care system has avoided being strained so far. 

 He also said he strongly supports the Rochester mask requirement that takes effect Wednesday.
