Which diseases require airborne precautions?

Airborne precautions are required for diseases spread by tiny particles that remain suspended in the air and can travel long distances. The key diseases requiring airborne precautions are tuberculosis, measles also called rubeola, varicella also called chickenpox, and disseminated herpes zoster also called shingles in immunocompromised patients. The patient must be placed in a negative pressure airborne infection isolation room. Healthcare workers must wear an N95 respirator or higher-level respirator that has been fit-tested. The door must remain closed.
