Just had a letter from public health, via my DS school letting me know that there are a number of cases of scarlet fever at his school. DH is being treated for encephalitis with steroids, which I have been told suppress his immune system. He is still very unwell but recovering at home. Can adults get scarlet fever? With just two days left of school I am thinking of just keeping DS home, but I am not sure if I am being unnecessarily over anxious....
