Some reasons why Norovirus spreads so much:
It is not killed by those Lysol/Clorox wipes or hand sanitizer gels (kills 99.9% of germs, guess who the .1% is)
A person is contagious for up to 48hrs AFTER symptoms END. This means that if you are sick for 24hrs, you are still contagious for another 2 days. And those virus particles you are shedding are not being killed with what most people are disinfecting with.

Wash your hands with soap and hot water, and if you are sick, stay home for 2 days after symptoms stop.

AHKTUALLY the 0.1% is intended to cover their asses in regards to spore forming bacteria since these things will not kill hearty spore formers like C. difficile and B. anthracis.

For a long time it was assumed or even thought to be known that these things work against norovirus.

Nowadays cleaners used in healthcare settings and (usually/hopefully) schools and congregate living facilities cover norovirus

Also, the immunity window after recovering from it is short and the virus lives on surfaces for quite a while (weeks I think?).

So it is possible to re-infect yourself after getting over it if surfaces aren't properly and completely disinfected.

Edit: immunity after infection is more like 2-6 months and the virus can last on surfaces up to 4 weeks.

I thought there was a 6 month immunity after?

Ya, looks like what I said was incorrect. The virus can last on surfaces up to 4 weeks and immunity to a certain strain lasts between 2 months and 6 months, depending on who you ask.
