Summary
Noroviruses (NoVs) are now the leading cause of gastroenteritis outbreaks and sporadic cases in all age groups. Current prevention focuses on hygiene measures due to the lack of a vaccine.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- Noroviruses (NoVs) were historically underestimated as a cause of gastroenteritis, often considered secondary to rotaviruses.
- Advancements in molecular diagnostics have revealed the significant epidemiological impact of NoVs.
Purpose of the Study:
- To provide a comprehensive overview of norovirus (NoV) morphology, genetics, transmission, pathogenesis, and control strategies.
- To highlight the current understanding of NoVs as a primary cause of viral gastroenteritis.
Main Methods:
- This review synthesizes existing knowledge on noroviruses.
- Information was gathered through a review of relevant scientific literature.
Main Results:
- Noroviruses are now recognized as the leading cause of non-bacterial gastroenteritis outbreaks.
- They are also a major cause of sporadic gastroenteritis in both children and adults.
- No effective vaccine is currently available for norovirus infection.
Conclusions:
- Norovirus infections pose a significant public health challenge globally.
- Prevention relies heavily on stringent personal and community hygiene practices.
- Further research into vaccine development is warranted.

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...
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...
What are Viruses?
Overview
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...
Introduction to Virus
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...
Gastritis-I: Introduction and Types
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
