Ottawa County - April 8, 2021

Effective Reproduction Number (Rt)

After a rise in the second half of March Rt is estimated to be at around 1.0.

Projected Incidence

An increase in cases seems likely, though the extent of the increase is uncertain.  Continued masking and social distancing will be critical to preventing large increases.

Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases has been on the rise since mid-March.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
