  • An evaluation of 10 different web-based COVID-19 symptom checkers found that the number of COVID-19 cases that were assessed correctly varied considerably between different checkers, with Symptoma performing the best. The study assessed 50 COVID-19 case reports along with 410 non-COVID-19 controls and found that only two symptom checkers achieved a good balance between sensitivity and specificity.
