The headline is also completely misleading as nowhere in the article does he quote the Chief Medical Officer actually saying anything about epidemics.
There is no typhoid or cholera in the UK as we have effective water treatment and sanitation. Neither is there bubonic plague. Measles happened in Wales due to low uptake of MMR, it could just have easily happened in a posh bit of London. It turned out the local paper in Wales had been especially anti-MMR so they had unusually low uptake.
Moving on to the next paragraph, urticaria is not contagious so there is no risk from unhygenic people in hostels sharing bedding.
His concerns about canned and frozen foods are also incorrect as most canned and frozen vegetables are high in vitamins, and can be higher than fresh as they are processed so quickly.
Smallpox is a dead disease unlike his claims, I suspect he means polio but that is on the rise due to problems in vaccinating in countries with civil war and Islamic extremists claiming polio vaccination is a Western plot to poison their children.
The best bit of the article is when he says he doesn't want it passed on the Public Health England as the last time they responded to him, their response was poorly researched!!!!
I wish I could find this article funny but it's depressing that anyone could read it and think he knows what he's talking about.
