Insights

Respiratory syncytial virus (RSV) was the main cause of severe pneumonia in young children in Nepal. This study highlights RSV as a dominant viral pathogen in hospitalized children with severe pneumonia.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Public Health

Background:

  • Pneumonia is a major global cause of childhood mortality, especially in low-income countries.
  • Limited data exists on the viral causes of severe pneumonia in these high-burden regions.

Purpose of the Study:

  • To investigate the viral etiology of severe pneumonia in young children in Nepal.
  • To identify the predominant respiratory viruses associated with severe pneumonia hospitalizations.

Main Methods:

  • Analysis of nasopharyngeal aspirates from 629 children (2-35 months) with severe pneumonia in Kathmandu, Nepal (2006-2008).
  • Detection of 7 respiratory viruses using reverse transcription polymerase chain reaction (RT-PCR).

Main Results:

  • Respiratory viruses were detected in 30% of children.
  • Respiratory syncytial virus (RSV) was the most frequently identified virus (14%), followed by influenza A (4.5%) and parainfluenza virus (PIV) types (3, 1, 2).
  • Severe pneumonia peaks coincided with RSV infection peaks, particularly during the monsoon and winter seasons.

Conclusions:

  • Respiratory syncytial virus (RSV) is the dominant viral pathogen causing severe pneumonia in hospitalized young children in Nepal.
  • Understanding viral etiologies is crucial for managing childhood pneumonia in resource-limited settings.

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...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
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...
