Insights

Emerging respiratory viruses like MERS-CoV and H7N9 pose global health risks. Understanding their transmission and pathogenesis is crucial for effective prevention and control strategies.

Area of Science:

  • Virology
  • Public Health
  • Epidemiology

Background:

  • Recent emergence of novel respiratory viruses, including MERS-CoV, H7N9 influenza A, H3N2 variant influenza, and adenovirus 14p1.
  • MERS-CoV and H7N9 influenza A remain significant global public health threats.
  • Limited understanding of the pathogenesis and transmission modes for MERS-CoV and H7N9.

Purpose of the Study:

  • To highlight the urgent need for research into emerging viral respiratory pathogens.
  • To emphasize the gaps in knowledge regarding the epidemiology and transmission dynamics of these viruses.
  • To advocate for a coordinated global response to address these public health concerns.

Main Methods:

  • This study is a review and synthesis of current knowledge on emerging respiratory viruses.
  • Analysis of the public health impact and research gaps for MERS-CoV and H7N9.
  • Identification of the need for enhanced surveillance and research collaboration.

Main Results:

  • Several novel viruses causing respiratory infections have emerged globally in the last decade.
  • Key viruses of concern include Middle East respiratory syndrome coronavirus (MERS-CoV) and H7N9 influenza A.
  • Significant knowledge gaps exist in understanding the pathogenesis and transmission of these viruses.

Conclusions:

  • A coordinated global effort is essential to combat emerging viral respiratory infections.
  • Further research is critically needed to understand the epidemiology and transmission dynamics of MERS-CoV and H7N9.
  • Improved understanding will facilitate the development of effective intervention and prevention strategies against fatal respiratory diseases.

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

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...

Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Common Respiratory Disorders01:31

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity 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...
