Lucas County - April 20, 2021

Effective Reproduction Number (Rt)

Rt has oscillated around 0.9 for most of the past 6 weeks, spiking above 1.0 in late March to early-April.

Projected Incidence

Daily incidence is most likely to slightly increase 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.
