是不是传染病得问医生哦
有的水土不服或者热毒长得疹子就不会传染
麻疹 手足口传染的 小儿急疹 川崎病不传染
google了一下
疹子出来了就不传染了 没出疹子发烧的时候传染
不需要抗生素 会自己好的 我家宝宝1岁的时候得的 因为拉肚子脱水有输液 但没有用抗生素 烧了2-3天 出了疹子就好了 疹子很快就退了 好像大部分的宝宝都是断奶以后得的急疹
Roseola is spread from person to person via respiratory fluids or saliva of infected individuals. The exact period an infected person is contagious for is unclear but it is most likely spread during the febrile phase of the illness when there are no outward signs that the child is infected with the virus.
