contagious or not?

This isn't near what im studying, but from my basic biology course the "symptoms" of being sick is basically the body doing anything it can to remove or eliminate bacteria. Coughing and sneezing clears bacteria from the air ways (as mucus secretion also helps kill bacteria). Inflammation comes from bacteria either infecting new cells and/or the increase in antibodies at the sites of infection causing pressure on the nerves their.

hopefully somebody more knowledgeable can answer this better...i'm pretty sure my answer sucks. Just don't go getting close with your "friend", that will increase your risk of getting sick too

funny enough, i've taken a course in immunulogy but i don't think we ever said how long you stay contagious.

you're about half right. some symptoms are your body trying to fight off the infection, some are directly caused. (cough, fever = body caused, diarreah = bacteria caused, that type of stuff). but generally, symptoms don't get noticeable for a couple days after you get sick.

making an educated guess, she's probably gonna be contagious tomorrow. I don't really know when people have symptoms but aren't contagious. Guessing, i'd think that only happens when only certain symptoms are left and they're tapering off, because at that point the level of bacteria/etc in your body is low enough that nobody will catch it but your body isn't quite finished eliminating or recovering from it yet.
