Williams County - February 17, 2021

Effective Reproduction Number (Rt)

The most recent data suggests an Rt spiking well above 1.0 in early January, but returning to levels below 1.0 since that time.  Whether the recent increase represents the beginning of a sustained trend remains to be seen.

 

Projected Incidence

Daily incidence appears most likely to continue to decline gradually in the coming two weeks.  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 since mid-January.  A low ratio of asymptomatic to symptomatic cases facilitates mitigation efforts since symptomatic individuals usually isolate.
