I want to find cases where Sars-associated coronavirus is identified as the cause of diseases classified elsewhere, with a high level of specificity, and including any timing, with an accuracy scale of 100, and a single occurrence of the item in the panel. The query should focus on diagnoses related to certain infectious and parasitic diseases, specifically bacterial and viral agents as the cause of diseases classified elsewhere, and coronavirus as the cause of diseases classified elsewhere, with a synonym status of false.
