Hello sospiri, nice to hear from you, I like your wife got an infection very early in my life, 6 months old or so, my sister Jane both got Whooping Cough in the 1947 epidemic, I survived and sadly she died.It must have been a very trying experience for her, when a boy I knew a couple of children who caught Polio in the 50's epidemic, in Birmingham luckily they survived due to the prompt treatment they received in Birmingham's hospitals, which I believe were very good. Regards Paul
