Insights

Rotavirus infection affects nearly 40% of young children with acute gastroenteritis in Nepal. Enzyme immunoassay (EIA) is a more sensitive diagnostic tool than latex agglutination (LA) for detecting Rotavirus antigen.

Area of Science:

  • Pediatrics
  • Virology
  • Infectious Diseases

Background:

  • Rotavirus is a leading cause of severe diarrheal disease in infants and young children globally.
  • Gastroenteritis in children under five years of age poses a significant public health challenge.
  • Understanding the incidence of specific viral pathogens is crucial for effective disease management.

Purpose of the Study:

  • To determine the incidence of Rotavirus infection in children under five years of age presenting with acute gastroenteritis.
  • To evaluate diagnostic methods for Rotavirus antigen detection in faecal samples.

Main Methods:

  • Faecal samples were collected from 160 children under five with acute gastroenteritis over one year.
  • Enzyme immunoassay (EIA) was used to detect Rotavirus antigen.
  • Latex agglutination (LA) was used to compare sensitivity with EIA.

Main Results:

  • Rotavirus antigen was detected in 38.7% of the faecal samples.
  • Co-infections with other pathogens were observed in positive samples.
  • Enzyme immunoassay (EIA) demonstrated higher sensitivity compared to latex agglutination (LA).

Conclusions:

  • This study reports the first documented incidence of Rotavirus infection in children in Nepal.
  • Enzyme immunoassay (EIA) is a more sensitive method for Rotavirus antigen detection than latex agglutination (LA).
  • Findings highlight the importance of Rotavirus surveillance and accurate diagnostics in pediatric populations.

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Cholera01:25

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
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...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
