Insights

WU polyomavirus (WUPyV) was frequently detected in South Korean children with respiratory infections. However, its specific role in illness remains unclear due to frequent coinfections with other respiratory viruses.

Area of Science:

  • Virology
  • Pediatrics
  • Infectious Diseases

Background:

  • WU polyomavirus (WUPyV) is a known human polyomavirus.
  • Respiratory tract infections are common in children globally.
  • The clinical significance of WUPyV in pediatric respiratory illness requires further investigation.

Purpose of the Study:

  • To determine the prevalence of WU polyomavirus (WUPyV) in children with acute lower respiratory tract infections in South Korea.
  • To assess the role of WUPyV as a coinfecting agent with other respiratory viruses.

Main Methods:

  • Retrospective analysis of respiratory samples from children.
  • Detection of WU polyomavirus using molecular methods.
  • Identification of coinfections with common respiratory viruses.

Main Results:

  • WU polyomavirus (WUPyV) was detected in 7% of children with acute lower respiratory tract infections (34/486).
  • WUPyV was found in 4.2% of asymptomatic children (3/72).
  • WUPyV was detected as a coinfection in 67.6% of cases with other respiratory viruses.

Conclusions:

  • WU polyomavirus (WUPyV) is prevalent in South Korean children presenting with respiratory symptoms.
  • The frequent detection of WUPyV alongside other respiratory viruses complicates the determination of its independent etiological role.
  • Further research is needed to elucidate the specific clinical impact of WUPyV in pediatric respiratory infections.

Respiratory Syncytial Virus Disease01:29

Respiratory 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...
Poliomyelitis01:17

Poliomyelitis

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...
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...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Acute Pharyngitis01:30

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
