I want to find all cases of Coronavirus infection, unspecified, with any timing, and set the specificity scale to 0, accuracy scale to 100, and total item occurrences to 1, using the ICD10_ICD9 code (B34.2) within the Diagnoses, Certain infectious and parasitic diseases, and Other viral diseases categories.
