Abstract

Insights

Nosocomial mpox (monkeypox) transmission is rare, primarily linked to sharps injuries. Current infection control practices are effective in preventing healthcare-associated mpox spread.

Area of Science:

  • Infectious Diseases
  • Epidemiology
  • Public Health

Background:

  • The 2022 global mpox (monkeypox) outbreak raised concerns about healthcare-associated transmission.
  • Limited data existed on the risk of nosocomial mpox spread in healthcare settings.

Purpose of the Study:

  • To evaluate the risk of mpox transmission to healthcare personnel (HCP) and patients.
  • To analyze factors associated with nosocomial mpox transmission during the 2022 outbreak.

Main Methods:

  • Review of reported cases of mpox exposure in healthcare settings.
  • Analysis of transmission events involving healthcare personnel and patients.

Main Results:

  • Nosocomial mpox transmission has been infrequent.
  • Identified risk factors include sharps injuries and lapses in transmission-based precautions.
  • Effective infection control measures significantly mitigate transmission risk.

Conclusions:

  • Current infection control practices, including standard and transmission-based precautions, are highly effective in preventing mpox spread.
  • Healthcare facilities should reinforce adherence to infection control protocols.
  • Avoidance of needles and sharp instruments during diagnostic sampling is crucial.

Transmission-based Precautions II: Airborne and Protective Environment

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...

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...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

PPE Use in Healthcare Settings I: Donning

Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

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.
