Effective Reproduction Number (Rt)
The most recent data suggests an Rt remaining below 1.0 but steadily increasing since mid-February.
Daily incidence appears most likely to continue to remain at similar levels in the coming two weeks, though considerable uncertainty exists. Continued masking and social distancing will be critical to preventing renewed increases in cases.
Asymptomatic to Symptomatic Ratio
The ratio of asymptomatic to symptomatic cases appears to have remained at consistently low levels over the last 6 weeks, but has shown a gradual upward trend in the most recent 3-4 weeks. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
