Norovirus test is intended to CHECK YOUR GENETIC RESISTANCE TO NOROVIRUS.
Norovirus (winter vomiting bug) is a highly contagious virus that causes vomiting, diarrhea and stomach cramps. Norovirus is the group of RNA-containing viruses that belong to the Caliciviridae family. Norwalk virus is the only species of the genus Norovirus. Serotypes, strains and isolates include Norwalk virus; Hawaii virus; Snow Mountain virus; Mexico virus; Desert Shield virus; Southampton virus; Lordsdale virus and Wilkinson virus. The RNA genome in noroviruses easily mutates to produce new norovirus types.
Viruses in Norovirus are non-enveloped, with icosahedral geometries.
Noroviruses are the common cause of gastroenteritis (90% of cases).
The virus is transmitted:
- by fecally contaminated food or water;
- by person-to-person contact (in 62-84% of cases) via aerosolization of vomited virus and subsequent contamination of surfaces.
Symptoms of norovirus infection include:
- nausea – usually the first symptom;
- vomiting – sometimes violent and sudden (more common for children);
- stomachache (abdominal pain);
- abdominal pain or cramps;
- watery or loose nonbloody diarrhea;
- suddenly feeling unwell and lethargic (malaise);
- fever and chills, usually mild;
- myalgias (body aches);
- loss of taste and appetite;
- tachycardia (fast heart rate);
- arterial hypotension;
- the absence of tenderness of the abdominal wall;
