B. A patient with any acute respiratory illness AND having been in contact with a confirmed or probable COVID-19 case (see definition of contact) in the last 14 days prior to symptom onset;ORC. A patient with severe acute respiratory illness (fever and at least one sign/symptom of ...
In the same vein, cyberloafing meets the definition of withdrawal behavior because the employee avoids working and spends less time working than they are expected to (Askew et al., 2014). In addition, cyberloafing, which is a form of withdrawal behavior from work, can buy employees time for ...
We note that our definition of co-location is more robust than previous literature30,31 since we represent a social contact from stop locations, thus reporting a co-location event between two people when they share the same stationary point. We aggregate co-location events in four different ...
Unprecedented public health interventions including travel restrictions and national lockdowns have been implemented to stem the COVID-19 epidemic, but the effectiveness of non-pharmaceutical interventions is still debated. We carried out a phylogenetic

Such a definition is similar to that adopted by most contact tracing apps which exploit Bluetooth or GPS to decide a contact when two users are in a short distance. As smartphone users report data in a very low and irregular frequency, the contributed data are typically sparse. We would ...
This historically-grounded definition of the frontier captures both dimensions of frontier life: population sparsity and isolation from urban centers. We then construct a novel, county-level measure of TFE, which captures the number of years that each county spent on the frontier from 1790 to 1890...
