Rotavirus infection in children presenting with acute gastroenteritis Ibadan, Nigeria

Insights

Rotavirus infection was detected in 21% of Nigerian children with acute gastroenteritis. Infants aged 4-6 months showed the highest rotavirus infection rates, with no cases found in children over two years old.

Area of Science:

  • Pediatrics
  • Virology
  • Infectious Diseases

Background:

  • Acute gastroenteritis is a significant cause of childhood illness globally.
  • Rotavirus is a leading viral pathogen responsible for severe diarrheal disease in infants and young children.

Purpose of the Study:

  • To determine the prevalence of rotavirus in children with acute gastroenteritis in Ibadan, Nigeria.
  • To investigate the age distribution of rotavirus infections in affected children.

Main Methods:

  • Faecal samples were collected from 84 children with acute gastroenteritis and 28 controls.
  • Enzyme-linked immunosorbent assay (ELISA) was used to detect rotavirus antigens in faecal samples.

Main Results:

  • Rotavirus was detected in 18 (21%) of the gastroenteritis cases, with no detection in the control group.
  • In-patients had a higher prevalence (25%) compared to out-patients (10%).
  • The highest infection rate (67%) was observed in children aged 4-6 months, followed by 7-12 months (33%), 0-3 months (13%), and 13-24 months (16%).

Conclusions:

  • Rotavirus is a common cause of acute gastroenteritis in children in Ibadan, Nigeria.
  • Infants between 4 and 6 months are most vulnerable to rotavirus infection.
  • The findings highlight the need for rotavirus surveillance and potential intervention strategies in the region.

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 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...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Inflammatory Bowel Disease IV: Clinical Manifestations

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
