and regular cleaning of surfaces and objects used in patient care . The medical
worker should wear a mask when a patient may cough or sneeze in the face of
the medical worker or student. This practice is extremely effective in avoiding
TB. All health care workers and students in the health professions are to be fittested
and provided with high efficiency particulate
air (HEPA) filter masks (Figure 6-11)
when treating patients who are under Respiratory
Precautions status as well as those having
symptoms of respiratory diseases. Patients
who are under Respiratory Precautions must

the facility, as their sputum may harbor the
organism for several days and infect the
unprotected worker and any others who may
have come in contact.
