回复: stomach flu
如果你发烧就有传染性，尽量少接触人。
我女儿生病我都是让她请假一周，完全好了才上学，减少传染的同时孩子也恢复得比较好。
不发烧也会传染的，轮状病毒也是这样，轮状病毒只是其中的一种而已。只要是近距离接触就可能传染，我儿子和老公都没发烧，只有我发烧了。我早就作好牺牲准备了，因为儿子先出现症状，每次他生病我无一例外会感染，因为这个接触是无法避免的。一起睡觉，用一个勺子自己吃同时喂他。
儿子我以前很少让他长时间在室内场所玩，在外面比较安全，但一来冬天外面没地方玩，二来他很快要上preschool了， 这些避免不了，所以开始让他跟很多孩子混在一起玩，有的孩子还告诉我自己生病了，所以很快被传染了。
How long am I contagious when I have the stomach flu
"It depends on which virus is causing your stomach flu (viral gastroenteritis). The contagious period – the time during which a sick person can give the illness to others – is slightly different for each virus," explains
Douglas Marquess, MD, who is board certified in internal medicine at Baptist Medical Associates.
Norovirus is the most common cause of viral gastroenteritis in adults. Symptoms appear within one to three days of exposure.
"With norovirus, you’re contagious from the moment you begin to feel ill. Although you typically feel better after a day or two, you’re contagious for at least three days after you’ve recovered," Dr. Marquess says.
Some people may be contagious for up to two weeks after recovery. Also, children are often contagious for a longer period than are adults.
Rotavirus is the leading cause of viral gastroenteritis in infants and young children. Symptoms of rotavirus appear one to two days after exposure. But you’re contagious even before you develop symptoms, and you typically remain contagious for two weeks after you've recovered.
For these reasons, it’s important to wash your hands frequently and thoroughly. The viruses that cause gastroenteritis are spread through close contact with infected persons, such as by sharing food or eating utensils.
"Washing your hands is the most effective way to stop the spread of these viruses to others," Dr. Marquess adds.
