Ashtabula County - April 28, 2021

Effective Reproduction Number (Rt)

Rt increased steadily until mid April, but still remains below 1.0 for the past 6 weeks.

Projected Incidence

Case numbers are expected to decrease slightly in the coming 2 weeks, although considerable uncertainty exists.  Continued masking and social distancing will be critical to preventing large increases.

Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases appears to have declined gradually over the past two weeks.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
