What are the different precautions to prevent disease transmission?

What are the 3 types of transmission based precautions?

Transmission-Based Precautions. There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.

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 the 4 main universal precautions?

Standard Precautions apply to 1) blood; 2) all body fluids, secretions, and excretions, except sweat, regardless of whether or not they contain visible blood; 3) non-intact skin; and 4) mucous membranes.

What are examples of transmission based precautions?

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.

  • 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.

Do all airborne precautions require n95?

The minimum respiratory protection required is an N95 respirator for routine patient care and aerosol-generating procedures in patients with diseases requiring airborne precautions, viral hemorrhagic fever, and possibly for emerging novel pathogens and pandemic influenza.

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.

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.

What is difference between standard precautions and universal precautions?

Standard precautions were developed by the CDC to synthesize the major features of universal precautions, which were designed to reduce the risk of transmission of bloodborne pathogens, and body substance isolation, which was designed to reduce the risk of transmission of pathogens from moist body substances.

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 five universal precautions?

5 Steps of Universal Precautions

  • Education.
  • Hand washing.
  • Use of protective barriers (Personal Protective Equipment (PPE))
  • Cleaning of contaminated surfaces.
  • Safe handling/disposal of contaminated material.

What is the use of transmission based precautions specific to?

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 the most effective way to control transmission of infection?

The most important way to reduce the spread of infections is hand washing – always wash regularly with soap and water. Also important is to get a vaccine for those infections and viruses that have one, when available. See the OSH Answers Hand Washing – Reducing the Risk of Common Infections for more details.

What is the purpose of transmission based precautions?

In many different healthcare settings, transmission-based precautions are used to help stop the spread of germs from one person to another. The goal is to protect patients, their families, other visitors, and healthcare workers—and stop germs from spreading across a healthcare setting.
