Effective Reproduction Number (Rt)
After climbing through most of March Rt briefly spiked to approximately 1.2, and has declined in the recent weeks.
Following a surge in late March, and despite moderate uncertainty, it appears most likely that daily case counts will decline in the coming two weeks. Continued masking and social distancing will be critical to preventing increases.
Asymptomatic to Symptomatic Ratio
The ratio of asymptomatic to symptomatic cases appears accelerated during the second half of March, peaking at a moderately high level of around 0.75 at the end of the month. A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
