Columbiana County - April 22, 2021

Effective Reproduction Number (Rt)

Rt appears to have oscillated around 1.0 over the past 3 weeks.

 

Projected Incidence

Daily incidence is most likely to remain steady, though there is considerable uncertainty given the small population size of the county.  Continued masking and social distancing will be critical to preventing increases.

 

Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases appears to have been on an upward trend over the past 3 weeks.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
