I want to find all instances of coronavirus in the database, regardless of specificity, with the highest level of accuracy, within any time frame, and with only one occurrence per patient. The query will be named "Coronavirus as @16:48:02" and will include a panel containing the item "Coronavirus as @17:27:29" from a previous query.
