Mercer County - January 27, 2021

Effective Reproduction Number (Rt)

The most recent data suggests an Rt above 1.0 since early January, although there has been a trend downward in recent weeks.  It will remain to be seen if this trend will continue.


Projected Incidence

Daily incidence appears most likely to decline in the coming two weeks.


Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases appears to have remained largely stable at a relatively low level since early December.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
