Insights

This study identified Sapovirus in 0.9% of young children with diarrhea in China. The detected strains belonged to two genogroups and three genotypes, including GI/1, GI/3, and GII/3.

Area of Science:

  • Virology
  • Epidemiology
  • Molecular Biology

Context:

  • Sapovirus is a significant cause of acute gastroenteritis in children worldwide.
  • Limited data exists on Sapovirus epidemiology and genetic diversity in China.

Purpose:

  • To investigate the epidemiologic features and genetic variance of Sapovirus in children under 5 years old with acute diarrhea in China.

Summary:

  • Fecal specimens from 1,110 children across nine Chinese provinces were analyzed using reverse transcriptase-polymerase chain reaction (RT-PCR).
  • Sapovirus was detected in 10 samples (0.9%).
  • Phylogenetic analysis of PCR products revealed two genogroups (GI and GII) and three genotypes (GI/1, GI/3, GII/3).

Impact:

  • This study provides crucial insights into the prevalence and genetic diversity of Sapovirus in a vulnerable pediatric population in China.
  • Findings can inform public health strategies and vaccine development for Sapovirus prevention.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
Coronavirus01:29

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...
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...
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...
