[Epidemiology of rotavirus infections in the Federal District, Brazil]

Insights

Rotavirus, a common cause of diarrhea in young children, was detected in 20.27% of fecal samples. Subgroup II rotaviruses were most prevalent, particularly in children aged 6-24 months.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Gastroenterology

Context:

  • Acute diarrhea is a significant health concern in infants and young children.
  • Rotavirus is a leading viral pathogen responsible for severe gastroenteritis in this age group.
  • Understanding rotavirus prevalence and characteristics is crucial for public health interventions.

Purpose:

  • To determine the prevalence of rotavirus infection in young children with acute diarrhea.
  • To characterize the rotavirus strains detected using polyacrylamide gel electrophoresis (PAGE).
  • To investigate the association of rotavirus infection with age and season.

Summary:

  • Rotavirus testing on 607 fecal samples from children aged 0-6 years with acute diarrhea revealed a prevalence of 20.27%.
  • Polyacrylamide gel electrophoresis (PAGE) analysis identified rotaviruses in 123 samples, with 87% classified as subgroup II (long profile).
  • Infection was most common in children aged 6-24 months (73.98%), with higher detection rates during the dry season (34.48%) and coldest months (June-July).

Impact:

  • This study provides valuable epidemiological data on rotavirus in a specific pediatric population.
  • Findings highlight the importance of age and seasonal factors in rotavirus transmission.
  • Results can inform vaccination strategies and public health policies for rotavirus prevention and control.

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...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
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...
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...
