What are the precautions for TB patients?
Wear proper personal protective equipment (PPE), including a NIOSH-certified fit-tested N95 respirator or a powered air-purifying respirator (PAPR), for the duration of home visit. Educate household members on risks of TB transmission and on contact investigation.
Is TB airborne or droplet?
tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing.
What are airborne precautions for TB?
Personal protective equipment is part of the airborne precautions protocol. All patients with suspected or confirmed active (infectious) TB should be directly admitted to the health care facility, bypassing the ER and immediately be put on airborne precautions in a negative pressure airborne isolation room.
How can we prevent the spread of TB?
Wash your hands after coughing or sneezing. Don’t visit other people and don’t invite them to visit you. Stay home from work, school, or other public places. Use a fan or open windows to move around fresh air.
What are the isolation precautions?
Isolation precautions are used to reduce transmission of microorganisms in healthcare and residential settings. These measures are designed to protect patients/residents, staff, and visitors from contact with infectious agents.
What are contact precautions?
Contact Precautions are intended to prevent transmission of infectious agents, including epidemiologically important microorganisms, which are spread by direct or indirect contact with the patient or the patient’s environment as described in I.B. 3. a.
Does TB require droplet precautions?
Airborne precautions are required to protect against airborne transmission of infectious agents. Diseases requiring airborne precautions include, but are not limited to: Measles, Severe Acute Respiratory Syndrome (SARS), Varicella (chickenpox), and Mycobacterium tuberculosis.
What type of mask is used for tuberculosis?
Patients with infectious TB should wear a surgical mask to prevent expelling droplet nuclei into the air.

What PPE is used for TB?
respirators (PAPR) are used to filter the air of small infectious particles such as TB bacteria or the SARS virus before entering the respiratory tract.
How long is isolation for tuberculosis?
Note: Home isolation is recommended for the initial three to five days of appropriate four-drug TB treatment.
How long do TB particles stay in the air?
Viable mycobacteria can persist in sputum for weeks after the onset of therapy,2 and isoniazid-susceptible TB bacilli in droplet nuclei containing isoniazid were demonstrated to remain viable after 12 hours airborne.

What are the 5 universal precautions?
Hand Hygiene. Hand hygiene is the most important measure to prevent the spread of infections among patients and DHCP.
Does TB need isolation?
Persons who have or are suspected of having infectious TB disease should be placed in an area away from other patients, preferably in an airborne infection isolation (AII) room.
Can TB live on clothes?
