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...
Transmission-based Precautions II: Airborne and Protective Environment01:25

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...
Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
Healthcare Associated Infections II: Preventive Measures01:22

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...
Transmission-based Precautions I: Contact, Enteric, and Droplets01:17

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

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...
Standard Precaution01:26

Standard Precaution

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...

Area of Science:

  • Critical care medicine
  • Infectious diseases
  • Public health

Background:

  • Emerging and high-consequence infectious diseases present significant critical care challenges.
  • Diagnostic uncertainty and limited medical countermeasures complicate management.
  • Nonspecific presentations can rapidly progress to severe conditions like shock, ARDS, or MODS.

Purpose of the Study:

  • To outline critical care management strategies for emerging and high-consequence infectious diseases.
  • To emphasize the importance of early recognition and supportive care.
  • To highlight the role of infection prevention and control.

Main Methods:

  • Review of current critical care practices for infectious diseases.
  • Focus on supportive care principles: fluid resuscitation, ventilatory support, oxygenation.
  • Emphasis on infection prevention: identify-isolate-inform principles.
  • Multidisciplinary team approach.

Main Results:

  • Optimized supportive care is crucial for patients with severe presentations.
  • Early recognition and intervention improve outcomes.
  • Adherence to infection prevention and control measures is vital.
  • Multidisciplinary care enhances patient management.

Conclusions:

  • Critical care clinicians need heightened vigilance for atypical presentations of emerging infectious diseases.
  • Awareness of diagnostic methods, vaccines, and therapeutics is essential.
  • Proactive and comprehensive management strategies are key to addressing these challenges.
