Preventing the potential spread of COVID-19 can involve a range of precautions such as isolation and the wearing of personal protective equipment, and education to individual patients, healthcare workers and the broader community. Once COVID-19 is diagnosed, various medications and therapeutic procedures may be considered, together with education for the patient and their families/caregivers.
These data elements are described below, with example SNOMED CT subsets for each
