- Norovirus (common viral gastroenteritis) is extremely efficient at establishing an infection. Wikipedia says it takes about 20 viruses. That's ridiculous, fascinating and kinda terrifying. Why are we so susceptible to infection by this virus? http://www.ncbi.nlm.nih.gov/pubmed/21876931 6 comments askscience
- In high school I was taught that viruses are not living beings. Reading this wikipedia article makes me assume that viruses are alive, but it doesn't seem to discuss this specifically. Can anyone explain it to a curious non-biologist? http://en.wikipedia.org/wiki/virus 83 comments science
