How long is the contagion period of gastroenteritis?

There are many causes of gastroenteritis. Some of them can be bacterial. Others are viral.

I'm going to address norovirus, a common source of viral gastroenteritis. Norovirus can cause illness that lasts about 72 hours. A person with Noro can be contagious from less than 12 hours before onset (as onset tends to be about 12 hours following exposure), then they're contagious while they're sick (another 72 hours), then they can continue to shed virus 48 hours afterwards.

That's about 5 and a half days a person can be contagous with norovirus. Things like Shigella and Salmonella can be contagious much longer than that (weeks, even MONTHS!). More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
