Portage County - April 20, 2021

Effective Reproduction Number (Rt)

Rt has remained less than 1.0 over the last several weeks.

Projected Incidence

Daily incidence is most likely to remain at similar levels in the coming two weeks.  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 risen from mid to late March, leveling off for the last month. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
