Insights

Rotaviruses and noroviruses cause significant childhood diarrhoea in Libya. This study found rotavirus in 31.5% and norovirus in 17.5% of young children with gastroenteritis.

Area of Science:

  • Virology
  • Pediatrics
  • Epidemiology

Background:

  • Rotaviruses and noroviruses are major global causes of acute gastroenteritis in children.
  • Diarrheal diseases represent a significant public health concern, particularly in developing countries.

Purpose of the Study:

  • To investigate the prevalence and characteristics of rotavirus and norovirus infections among young children with acute gastroenteritis in Tripoli, Libya.
  • To identify common rotavirus genotypes and norovirus genogroups.

Main Methods:

  • A cross-sectional study was conducted from October 2007 to September 2008.
  • Fecal samples from 520 children under five years old were analyzed using ELISA for rotavirus and real-time RT-PCR for norovirus.
  • Rotavirus genotypes and norovirus genogroups/types were determined.

Main Results:

  • Rotavirus was detected in 31.5% and norovirus in 17.5% of the samples.
  • Rotavirus was more prevalent in inpatients (35.8%) than outpatients (27.3%), while norovirus was more common in outpatients (21.2%) than inpatients (13.8%).
  • The most common rotavirus genotypes were P[8],G9 and P[8],G1. Noroviruses were predominantly genogroup II, genotype GII.4.

Conclusions:

  • Rotaviruses and noroviruses are significant viral pathogens contributing to gastroenteritis in young children in Libya.
  • Understanding the epidemiology and prevalent strains of these viruses is crucial for developing effective prevention and control strategies.

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...
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,...
Size and Structure of Viral Genomes01:26

Size and Structure of Viral Genomes

Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
