The present meaning assumes "considerable" to imply shut distance (much less compared to 2 metres) and extended get in touch with (greater than 15 mins). These are approximate thresholds.


Get in touch with mapping is likewise laborious and time taking in. A research study of get in touch with tracers in Sheffield reported that each meeting with a contaminated individual to determine their get in touches with took about 80 mins. The typical variety of considerable get in touches with determined for everyone contaminated with COVID-19 – about 30 get in touches with each situation – was likewise high. As a result, the work included is considerable.
