Prevalence of enteric adenovirus from acute gastroenteritis: a five year study

Insights

Enteric adenoviruses were endemic in hospitalized pediatric patients with acute gastroenteritis between 1981 and 1985. These viruses showed seasonal variations, impacting public health surveillance strategies.

Area of Science:

  • Virology
  • Pediatric Infectious Diseases
  • Public Health

Background:

  • Acute gastroenteritis is a common cause of hospitalization in children.
  • Adenoviruses are significant viral pathogens contributing to pediatric gastroenteritis.

Purpose of the Study:

  • To determine the prevalence and characteristics of adenoviruses in hospitalized children with acute gastroenteritis.
  • To investigate the seasonality and endemicity of enteric adenoviruses over a five-year period.

Main Methods:

  • Stool samples from 3932 pediatric patients were analyzed for adenovirus detection.
  • Adenovirus isolates were identified using genus-specific ELISA and cell culture (HEp-2 and 293 cells).

Main Results:

  • Adenoviruses were detected in 11.6% of children; enteric adenoviruses accounted for 8.3%.
  • Enteric adenoviruses demonstrated endemicity over five consecutive years (1981-1985).
  • A distinct seasonal pattern was observed in adenovirus detection rates.

Conclusions:

  • Enteric adenoviruses are a persistent cause of acute gastroenteritis in hospitalized children.
  • Understanding adenovirus seasonality is crucial for effective disease control and prevention strategies.
  • Comparative data on rotavirus prevalence were also noted in the study population.

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 Pyelonephritis I: Introduction01:27

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
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...
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...

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...

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
