Answer:
B.indirect contact with animal feces
Step-by-step explanation:
Norovirus is a type of small, round virus with a high infectious capacity and resistance and is able to remain on surfaces where the infected person has had contact, facilitating transmission to other people. This virus can be found in contaminated food and water and is a major contributor to viral gastroenteritis in adults, unlike rotavirus, which infects children more often.
Symptoms of norovirus infection include severe diarrhea followed by vomiting and often fever. This gastroenteritis is usually treated by resting and drinking plenty of fluids, because the virus has a high mutational capacity, that is, there are several types of norovirus, and its control is difficult.
Indirect contact with animal feces does not contaminate food with norovirus, but direct contact with contaminated hands, direct contact with work surfaces contaminated with infectious feces or vomiting and small drops of vomit that spread through the air when an infected person vomits may infect food with norovirus.
