The cholera man shook hands with a neighbor and dined on seafood (shrimp and oysters) with a colleague. Which of them could have contracted cholera from this person? Why are cholera vibrios often compared to a school of fish?

1) Vibrio cholerae infection most often occurs through water and food (for example, undercooked shellfish); also the source of infection is the feces of a sick person, therefore, a neighbor could become infected only if the person had traces of his excrement on his hands, and a colleague – only by eating undercooked shellfish (provided that they contained cholera vibrio);
2) the cholera vibrio is very active, the most “excellent runner” of the mobile microbes, moves due to the movement of the flagellum.
