I want to find patients who have been diagnosed with both Cough and Acute upper respiratory infections of multiple or unspecified sites, with the cough occurring before the acute upper respiratory infection, and with a high level of specificity and accuracy. The query will search for these events within the same encounter, and will not include synonyms or related terms.
