When it comes to viruses, Norovirus (a.k.a. Norwalk) is one nasty customer. If it weren't for the fact that symptoms disappear after two or three days, the human race would be in deep doo-doo. Literally. According to this detailed presentation
, it claims 23,000,000 victims annually - the highest rate of viral infection besides the common cold. You can get it from food, you can get it from contaminated surfaces and through inhalation of viral particles. It takes less than 100 particles to make people sick. NoV is shed in the feces at up to 10 million particles per infected gram. One single incident of projectile vomiting releases 30 million particles. People remain infectious usually for 72 hours after recovery, but may in some cases be infectious for up to 2 weeks. Viral particles can stay active on surfaces for days and even weeks. Surface contamination requires: 1 tbl of bleach/gal of water for stainless steel, food utensils and toys; 1-2/3 cups bleach/gal of water for porous surfaces and wooden floors. Removing viral particles from clothing requires laundering in water that's 60 degree C or higher.
Norovirus outbreaks are more common in winter (see pg 8 of the presentation) but reasons are unclear.
What can you do? Be a germ buster
and if you get infected, stay at home.
And now, I'm off to get some bed rest.
