Mercer County - March 26, 2021

Effective Reproduction Number (Rt)

The most recent data suggests an Rt remaining will below1.0 but increasing in recent days.  Whether this increase represents a sustained pattern remains to be seen.

Projected Incidence

Incidence appears likely to rise in the coming two weeks, though considerable statistical uncertainty exists given the relatively small population of the county.  Continued masking and social distancing will be critical to preventing substantial increases.

Asymptomatic to Symptomatic Ratio

The ratio of asymptomatic to symptomatic cases appears to have remained consistently low over the last 6 weeks until recent days.  Whether this increase represents a sustained pattern remains to be seen.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
