Summary
Human calicivirus (HuCV) was the primary cause of viral diarrhea in Ningxia children under two in 2011. This study investigated rotavirus, astrovirus, and adenovirus infections in acute diarrhea cases.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Context:
- Acute diarrhea remains a significant health concern, particularly in pediatric populations.
- Understanding the etiological agents of viral gastroenteritis is crucial for effective public health interventions.
- Ningxia province's epidemiological landscape for enteric viruses in 2011 was previously underexplored.
Purpose:
- To determine the etiological characteristics of human rotavirus (HRV), human calicivirus (HuCV), human astrovirus (HAstV), and human enteral adenovirus (HAdV) in Ningxia, China.
- To identify the predominant viral pathogens and their prevalence in acute diarrhea cases.
- To analyze co-infection rates and characterize HRV strains.
Summary:
- A total of 690 stool specimens from acute diarrhea cases in Ningxia were analyzed.
- Infection rates were: HRV (2.17%), HuCV (21.74%), HAstV (3.19%), and HAdV (6.52%).
- HuCV emerged as the main viral pathogen, with HRV serotypes G1, G3, and P[4] being predominant. Co-infections occurred in 4.20% of samples.
Impact:
- This research highlights HuCV as a major contributor to viral diarrhea in young children in Ningxia.
- Findings provide essential data for targeted prevention and control strategies against viral gastroenteritis.
- The study contributes to the understanding of viral etiology in a specific geographic region, informing future epidemiological surveillance.

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...

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...

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...
