Summary
Enteroviruses (EV) cause respiratory infections in infants and adults. These common viruses, including coxsackievirus A16 and enterovirus 71, are increasingly linked to severe pneumonia and emerging infectious diseases.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Context:
- Enteroviruses (EV) are common human pathogens within the Picornaviridae family, encompassing 108 serotypes across 4 species.
- EVs are responsible for diverse human pathologies, including upper and lower respiratory tract infections in both adults and infants.
- Recent studies identify EVs as the third leading cause of bronchiolitis in infants (1-12 months).
Purpose:
- To highlight the significant role of enteroviruses in respiratory infections.
- To underscore the association of specific enteroviruses like coxsackievirus A16 (CV-A16), enterovirus 71 (EV-71), and EV-104 with severe pneumonia.
- To emphasize the potential for EV respiratory strains to cause future emerging infectious diseases due to viral evolution.
Summary:
- Enteroviruses (EVs) are implicated in a spectrum of human illnesses, notably respiratory tract infections.
- Specific EVs, including CV-A16, EV-71, and EV-104, are identified as etiological agents of acute or fatal pneumonia in infants and adults.
- EVs, particularly respiratory strains, pose a growing threat due to frequent mutations and recombination, potentially leading to new infectious disease outbreaks.
Impact:
- Elevates awareness of enteroviruses as critical pathogens in respiratory illness, especially in vulnerable infant populations.
- Informs public health strategies for surveillance and control of enteroviral respiratory infections.
- Highlights the need for ongoing research into EV evolution and the emergence of novel strains with pandemic potential.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:27Influenza
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...
01:29Microbiota 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 like...
01:31Common 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,...

01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:26Human Virome
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
