Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

58
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...

Arboviral Encephalitis01:25

Arboviral Encephalitis

30
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Steps in Outbreak Investigation

704
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:

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

1.3K
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Transmission-based Precautions II: Airborne and Protective Environment

2.2K
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...

Summary

The 2014 Ebola epidemic in West Africa was historically large. Understanding Ebola virus disease epidemiology, pathogenesis, and prevention can reduce public fear of its spread.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Epidemiology

Background:

  • The 2014 West Africa Ebola virus disease outbreak was the largest recorded.
  • Media coverage amplified fears of a global Ebola pandemic due to patient travel.
  • Public anxiety stemmed from a lack of accurate information regarding Ebola virus disease.

Purpose of the Study:

  • To provide a comprehensive overview of Ebola virus disease.
  • To clarify the epidemiology, pathogenesis, clinical presentation, treatment, and prevention strategies.
  • To mitigate public fear and paranoia surrounding Ebola virus disease transmission.

Main Methods:

  • Literature review of Ebola virus disease.
  • Analysis of epidemiological data from the 2014 outbreak.
