Insights

Group A rotavirus infections were detected in 19.7% of diarrheic children in Malaysia, predominantly in those under two years old. This study details the rotavirus electropherotypes found across eight Malaysian hospitals.

Area of Science:

  • Virology
  • Pediatric Infectious Diseases
  • Public Health

Background:

  • Group A rotaviruses are a leading cause of severe diarrheal disease in young children globally.
  • Understanding the genetic diversity and geographic distribution of rotavirus strains is crucial for vaccine development and public health strategies.

Purpose of the Study:

  • To determine the incidence and electropherotype distribution of Group A rotaviruses in diarrheic children across eight Malaysian hospitals.
  • To provide comprehensive data on rotavirus epidemiology in Malaysia.

Main Methods:

  • Stool samples from 157 diarrheic children were screened for Group A rotavirus using latex agglutination.
  • Positive samples were further analyzed by RNA electrophoresis and electron microscopy for confirmation and genotyping.
  • Rotavirus electropherotypes were characterized based on RNA segment migration patterns.

Main Results:

  • An overall incidence of 19.7% for Group A rotavirus was observed, with significant geographical variation (9.5%–39.1%).
  • Infections were most common in children under two years of age.
  • The predominant electropherotypes identified were Type IIC (51.6%) and Type IIG (35.5%), both characterized as 'long' patterns.

Conclusions:

  • This study presents the first comprehensive report on rotavirus electropherotypes from multiple locations in Malaysia.
  • The findings highlight the prevalence of specific rotavirus genotypes and their distribution, offering valuable insights for disease surveillance and control efforts in the region.

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

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...
