Effective Reproduction Number (Rt)
After remaining at low levels for several weeks, Rt has undulated around 1.0 for the last 2 weeks. However, this estimate is considered somewhat unreliable given sporadic patterns of reported cases in the county.
Projected Incidence
Incidence appears most likely to remain at similar levels, but there is some uncertainty given sporadic patterns of reported cases in the county and small population size. Continued masking and social distancing will be critical to preventing increases.
Asymptomatic to Symptomatic Ratio
In mid-March, the ratio of asymptomatic to symptomatic increased to moderately-elevated levels, where it remains. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
