Norovirus in : Food handler · 517
Norovirus enters public talk in as “Food handler.” The figure to keep is 1968. It is not a dose, and this sentence is not a diagnosis. Start with hands, water, or food — the place you actually meet it. A clinical description of epidemic winter vomiting predates the particle.
A very-low-dose gut virus of schools and ships — soap and bleach surfaces, not alcohol-gel faith. An outbreak at a school in Norwalk, Ohio, in 1968 became the namesake after the agent was later visualized. Albert Kapikian and colleagues saw the Norwalk agent by immune electron microscopy in 1972.
Noroviruses are caliciviruses. Many genotypes exist; GII.4 has often dominated global waves. Reviews often cite on the order of 10 to 100 particles — conceptually very low compared with many gut microbes. Closed populations — ships, camps, hospitals, schools — turn vomit and feces into efficient indoor spread.
Alcohol gels are less reliable than soap and water on hands; hypochlorite is the usual talk for hard surfaces after vomit. Norovirus is a tiny, tough calicivirus that needs very few particles to start a vomiting chain in a school or ship. Soap, stay-home manners and bleach on the right surfaces do more than panic about cruises.
