Effective Reproduction Number (Rt)
The most recent data suggests an Rt remaining below 1.0 since early January. Whether a recent rise in Rt will continue remains to be seen.
Daily incidence appears most likely to continue to decline slightly in the coming two weeks, though considerable uncertainty exists. Continued masking and social distancing will be critical to maintaining downward momentum in new cases.
Asymptomatic to Symptomatic Ratio
The ratio of asymptomatic to symptomatic cases appears to have remained largely stable at relatively low levels over the last 6 weeks. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
