Transmission-Based Precautions. There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
What are the three types of transmission based precautions used along with standard precautions?
The three categories of Transmission-based Precautions are: Contact Precautions, Droplet Precautions, and Airborne Precautions, and are based on the likely routes of transmission of specific infectious agents.
What are examples of transmission based precautions?
- airborne transmission, e.g., pulmonary tuberculosis, chickenpox, measles.
- droplet transmission, e.g., influenza, pertussis (whooping cough), rubella.
- contact transmission (direct or indirect), e.g., viral gastroenteritis, Clostridium difficile, MRSA, scabies.
When should transmission based precautions be used?
Use transmission-based precautions when caring for patients known or suspected of being infected with agents transmitted by contact, droplet or airborne routes. Transmission based precautions are used in addition to standard precautions.
What are the 10 standard precautions?
- Hand hygiene.
- Use of personal protective equipment (e.g., gloves, masks, eyewear).
- Respiratory hygiene / cough etiquette.
- Sharps safety (engineering and work practice controls).
- Safe injection practices (i.e., aseptic technique for parenteral medications).
- Sterile instruments and devices.
What are the three basic elements of airborne precautions?
Airborne precautions consist of a three-level hierarchy of (1) administrative controls, (2) environmental controls, and (3) respiratory-protection controls.
What infections require airborne precautions?
Diseases requiring airborne precautions include, but are not limited to: Measles, Severe Acute Respiratory Syndrome (SARS), Varicella (chickenpox), and Mycobacterium tuberculosis. Airborne precautions apply to patients known or suspected to be infected with microorganisms transmitted by airborne droplet nuclei.
What are standard transmission precautions?
Transmission-Based Precautions are the second tier of basic infection control and are to be used in addition to Standard Precautions for patients who may be infected or colonized with certain infectious agents for which additional precautions are needed to prevent infection transmission.
What is meant by transmission based precautions?
Transmission based precautions are additional measures focused on the particular mode of transmission and are always in addition to standard precautions. They are grouped into categories according to the route of transmission of the infectious agent.
What type of mask is required to prevent droplet transmission?
If on Droplet Precautions, the patient should wear a surgical- type face mask and follow cough etiquette when outside of their room. For patients in airborne infection isolation, the patient should also wear a surgical face mask and follow cough etiquette.
What are additional precautions and when should they be used?
Additional precautions are measures used in addition to Standard Precautions when extra practices are required to prevent transmission of specific infectious diseases.
Is TB airborne or droplet?
M. 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. TB is spread from person to person through the air.
Why is standard precautions important?
Standard precautions are meant to reduce the risk of transmission of bloodborne and other pathogens from both recognized and unrecognized sources. They are the basic level of infection control precautions which are to be used, as a minimum, in the care of all patients.
What are the 5 basic principles of infection control?

- Using personal protective equipment.
- Safe handling and disposal of sharps.
- Safe handling and disposal of chemical waste.
- Managing blood and bodily fluids.
