Insights

This glossary clarifies terms used in infectious disease epidemics and pandemics, like COVID-19. Understanding these definitions aids public health responses and citizen participation during global health crises.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Diseases

Background:

  • The COVID-19 pandemic, caused by SARS-CoV-2, highlights the need for clear communication regarding public health measures.
  • Misinformation and misuse of terminology hinder effective citizen participation in disease control strategies.
  • Existing terminology surrounding epidemics and pandemics requires clarification for public understanding.

Framework:

  • This work reviews and differentiates key terms related to infectious disease epidemics and pandemics.
  • The review focuses on terms relevant to SARS-CoV-2 and the COVID-19 outbreak.
  • Definitions are provided to facilitate understanding of pathogen behavior and disease cycles.

Implementation:

  • The glossary aims to standardize information and facilitate the use of accurate terminology.
  • It addresses terms used in public health decision-making for infectious disease control.
  • The goal is to improve comprehension for the general public and stakeholders.

Implications:

  • Standardized terminology enhances understanding of epidemic and pandemic dynamics.
  • Clear communication supports effective implementation of public health measures like containment and quarantine.
  • Improved public understanding fosters greater participation in disease prevention and control efforts.

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 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...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

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...

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Concepts of Health and Illness01:29

Concepts of Health and Illness

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...
