Effective Reproduction Number (Rt)
The most recent data suggests an Rt below 1.0 in February and for the remainder of the month.
Daily incidence appears likely to remain stable 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 remained largely stable at a relatively low level over the last 8 weeks. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
