  "Description": "We propose a method to estimate the probability of an\nundetected case of COVID-19 in a defined setting, when a given\nnumber of people have been exposed, with a given pretest\nprobability of having COVID-19 as a result of that exposure.\nSince we are interested in undetected COVID-19, we assume no\nperson has developed symptoms (which would warrant further\ninvestigation) and that everyone was tested on a given day, and\nall tested negative.",
