I want to find patients with a diagnosis of acute respiratory infections in the respiratory system during any time period, with a high accuracy level, and the query will include both the specific diagnosis of acute respiratory infections and the broader category of respiratory system diagnoses, with the respiratory system diagnoses being constrained by the "Admit Diagnosis" modifier.
