Standard Precaution01:26

Standard Precaution

2.5K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.3K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Hand hygiene01:23

Hand hygiene

5.0K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Transmission-based Precautions II: Airborne and Protective Environment

1.7K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Cleaning, Sterilization, and Disinfection

9.3K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.3K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Area of Science:

  • Virology
  • Epidemiology
  • Public Health

Background:

  • The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in late 2019 and rapidly spread globally.
  • The World Health Organization declared the SARS-CoV-2 outbreak a pandemic in March 2020 due to its rapid international dissemination.
  • Despite global efforts, the number of SARS-CoV-2 infections continues to rise, necessitating enhanced preventive measures.

Purpose of the Study:

  • To review essential information regarding SARS-CoV-2, including its environmental stability and persistence.
  • To summarize effective protection strategies for both the general public and healthcare professionals.
  • To outline decontamination options and the efficacy of various disinfectants against SARS-CoV-2.

Main Methods:

  • Literature review of studies on SARS-CoV-2 transmission routes and environmental stability.
  • Compilation of recommended personal protective measures for different risk groups.
  • Analysis of research on the effectiveness of disinfectants against SARS-CoV-2 on various surfaces.

Main Results:

  • SARS-CoV-2 exhibits stability on common surfaces like glass, paper, and wood.
  • Effective prevention includes social distancing, mask usage, and rigorous hygiene practices.
  • The virus is susceptible to common disinfectants such as ethanol, sodium hypochlorite, and hydrogen peroxide.

Conclusions:

  • Comprehensive knowledge of SARS-CoV-2 characteristics is vital for effective pandemic control.
  • Multidirectional strategies encompassing personal protection and surface disinfection are essential.
  • Proper disinfection protocols are critical for limiting the environmental spread of SARS-CoV-2.
