Insights

Human adenovirus (HAdV)-40 and HAdV-41 are significant causes of acute gastroenteritis in Iranian children. Early detection using PCR aids in managing the illness and preventing unnecessary antibiotic use.

Area of Science:

  • Pediatrics
  • Virology
  • Epidemiology

Background:

  • Acute gastroenteritis is a leading cause of illness and death in young children globally.
  • Human adenovirus (HAdV) types 40 and 41 are common pathogens in pediatric gastroenteritis.

Purpose of the Study:

  • To determine the prevalence of HAdV-40 and HAdV-41 in hospitalized children with gastroenteritis in Iran.
  • To identify the etiological role of these viruses in pediatric acute gastroenteritis.

Main Methods:

  • A cross-sectional epidemiological study involving 2682 fecal specimens from children under 5 years old.
  • Samples collected from five pediatric centers in Iran between February 2012 and February 2013.
  • Polymerase chain reaction (PCR) used to detect HAdV-40 and HAdV-41.

Main Results:

  • HAdV-40 and HAdV-41 were detected in 5.18% (132/2682) of children with diarrhea.
  • Prevalence was significantly higher (58.3%) in infants under 12 months.
  • The male to female ratio was 1.7.

Conclusions:

  • HAdV-40 and HAdV-41 are significant etiological agents of acute gastroenteritis in Iranian children.
  • PCR offers a rapid diagnostic method, potentially leading to better patient outcomes and reduced antibiotic use.

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...

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...

Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...
