get her to a doctor
my sister has it too

but how old is she?

shes 14

i had some kinda red rashes all over too when am 2, my mum took me to doctor and the doctor said it was german meassle(i dunno how to spell "measel?"), my mum dun understand why i had it as she thought there're aready some kinda vacinne to it , and that i have taken since am new born.
anyway, she told me, the syndrom i had is, fever at night for 4days, and the rashes gone after 1 week left some dark marks which also dissapear after 1month, tats the reason she has been telling this story to me & her frens like 98times, cos she was so afraid that i'll need to carry the marks for the rest of my life!
