Effective Reproduction Number (Rt)
The most recent data suggests an Rt somewhat higher in the latter half of March, but generally remaining below 1.0.
Daily incidence appears most likely to continue to decline gradually in the coming two weeks. Continued masking and social distancing will be critical to maintaining this momentum.
Asymptomatic to Symptomatic Ratio
The ratio of asymptomatic to symptomatic cases appears to have gradually risen over the past 3-4 weeks, but overall remains low. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
