The only insane thing here is you.
Really? I’m not the one who thinks childhood diseases were eradicated by … what’s tops on your list? Better sanitation? I say it was modern science which gave us vaccines.
Was there a recent epic sanitation fail in the UK? Have the Brits forgotten about soap and water?
London suffering from shocking rise in rare 'Victorian' diseases
Looks like your theory was tested. From the article:
London is suffering a startling rise in diseases associated with Victorian times, official figures reveal today.It would appear that for one reason or another, enough people did not have their children vaccinated against easily controllable diseases. Because no vaccine is one hundred percent effective, what happened was a big enough breakdown in population immunity to give the diseases a foothold. All of this could have been prevented. Anti-vaccination cranks insured that it was not.Rare infectious illnesses including typhoid, whooping cough and scarlet fever have soared by 166 per cent in the past two years, with the number of cases of mumps - a disease easily prevented with vaccine - rising from 125 in 2007 to 393 last year - an increase of 214 per cent.
Enjoy the deaths.
