Patients are exposed to microbes by contact (direct contact, airborne, or otherwise) with other patients, family members, and contaminated healthcare equipment. Some of these are pathogenic (cause illness) and some are nonpathogenic (do not cause illness). But most microbes causing infection among patients are spread by direct contact on the hands of healthcare workers.
