Insights

Human rotavirus (HRV) infections caused 16.3% of acute diarrhea cases in Ghanaian children. HRV was linked to severe diarrhea but less vomiting, with subgroup II and serotypes 1 and 4 being most common.

Area of Science:

  • Pediatrics
  • Virology
  • Public Health

Background:

  • Acute diarrhea is a leading cause of childhood illness globally.
  • Rotavirus is a major viral pathogen responsible for severe diarrhea in infants and young children.
  • Understanding local rotavirus epidemiology is crucial for developing effective control strategies.

Purpose of the Study:

  • To determine the prevalence of human rotavirus (HRV) infection in children with acute diarrhea in Accra, Ghana.
  • To identify the clinical characteristics associated with HRV infection.
  • To characterize the HRV subgroups and serotypes prevalent in the study population.

Main Methods:

  • A 12-month prospective study was conducted in two hospitals in Accra, Ghana.
  • Stool samples were collected from children presenting with acute diarrhea.
  • Human rotavirus infection was detected, and subgroup/serotype analysis was performed. RNA electrophoresis was used to analyze HRV strains.

Main Results:

  • 16.3% of children with acute diarrhea were infected with HRV.
  • HRV infection was significantly associated with severe diarrhea.
  • Vomiting was less frequent in HRV-associated diarrhea compared to non-HRV diarrhea. Subgroup II HRV, particularly serotypes 1 and 4, was predominant. Seven distinct RNA electrophoretic patterns were observed.

Conclusions:

  • Human rotavirus is a significant cause of acute diarrhea in children in Accra, Ghana.
  • Clinical presentation varies, with HRV associated with severe diarrhea but less vomiting.
  • Further research into HRV strains and their impact is warranted for public health interventions.

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...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
