Portage County - April 8, 2021

Effective Reproduction Number (Rt)

Rt has remained under 1.0 for most of March, with higher numbers in the late March and early April. 

Projected Incidence

Following a surge in late March, and despite moderate uncertainty, it appears most likely that daily case counts will decline 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 has been on a gradual rise since mid-March.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
