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

Transmission-based Precautions II: Airborne and Protective Environment

2.1K
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...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

1.2K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

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

3.3K
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...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

1.2K
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Summary

Occupational legionellosis, including Legionnaires' disease and Pontiac fever, stems from Legionella bacteria exposure in workplaces. Industrial settings with cooling towers pose the highest risk, necessitating improved prevention strategies for workers.

Area of Science:

  • Environmental Health
  • Occupational Medicine
  • Infectious Diseases

Background:

  • Legionellosis, encompassing Legionnaires' disease (LD) and Pontiac fever (PF), is caused by Legionella bacteria.
  • LD is a significant cause of community- and hospital-acquired pneumonia, with increasing links to occupational settings.
  • Recognition of work-related risks for legionellosis is crucial for prevention.

Purpose of the Study:

  • To review and analyze occupational legionellosis cases documented in literature from 1978 to 2016.
  • To define the etiology, infection sources, at-risk work activities, infection rates, predisposing factors, mortality, and geographical distribution of occupational legionellosis.
  • To raise awareness of occupational legionellosis risks and inform prevention strategies.

Main Methods:

  • A comprehensive literature search was conducted on PubMed between January 31, 2015, and June 30, 2016.
  • Keywords included "Legionella pneumophila", "Legionnaires' disease", "Pontiac fever", "legionellosis", "employees", "workers", and "occupational".
  • Forty-seven articles reporting 805 cases (221 LD, 584 PF) between 1949 and 2015 were selected and analyzed.

Main Results:

  • Legionella pneumophila (58.5%) and Legionella feeleii (39.4%) were the primary causative agents.
  • Industrial settings (62.0%), office buildings (27.3%), and healthcare facilities (6.3%) were the most common workplaces.
  • Fatalities (4.1% mortality) were exclusively associated with LD; exposure to contaminated work-generated aerosols was the common infection source.

Conclusions:

  • Occupational legionellosis presents a broad spectrum of at-risk job categories, often linked to industrial facilities with cooling systems.
  • Workplace-generated aerosols contaminated with Legionella spp. are the primary route of infection.
  • Enhanced awareness and targeted prevention measures are essential for controlling this disease in occupational settings.
