My next door neighbour in Uni contracted meningacoccal (sp?) septicaemia, that hit him amazingly quickly aswell......he did have the rash-marks, so as soon as we noticed, we had him rushed into hospital.
Everyone living nearby, and who had come into contact with him over the last two days, had to take extra-strong antibiotics as a precaution, although he had the worst of it......he had to have the full spinal-tap operation, and was in hospital for a good few weeks because of it.
Glad it was caught early enough, though, Mr S1......get well soon!
