Effective Reproduction Number (Rt)
The most recent data suggests an Rt below 1.0 from mid January through mid February.
Projected Incidence
Daily incidence appears likely to continue to decline 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 declined steadily since the second week of January. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
