Columbiana County - April 7, 2021

Effective Reproduction Number (Rt)

The most recent data suggests an Rt remaining below 1.0 for the past 6 weeks.  However, this estimate is considered somewhat unreliable given sporadic patterns of reported cases in the county and small population size.

 

Projected Incidence

Incidence appears most likely to remain at similar levels, but there is some uncertainty given sporadic patterns of reported cases in the county and small population size.   Continued masking and social distancing will be critical to preventing increases.

 

Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases appears to remain low.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
