Girls hi ?? What could it be? I think it might be a rash because we had a temperature for 4 days and I didn't bathe her, only wiped her down Today this rash appeared, but it's all over the body and face ? Someone here wrote that they also had a high fever and then a rash appeared, it turned out to be a viral disease - Roseola? so is this not it? ??????
