Wash your hands and your mobile to avoid E coli

The recent research showed that there is harboured E. coli (Escherichia coli) in 16% of hands and 16% of mobile phones. The bacteria inhabit the human intentines. In 12 British cities the London School of Hygiene and Tropical Medicine and Queen Mary, University of London took nearly 400 samples from hands and mobile phones. Apparently Birmingham is the dirtiest city. There is 41% of contaminated hands and phones. In London it’s only 28%. Dr Val Curtis said that there is clear and strange difference between north and south of England.
So, what is the problem? Don’t people know how to wash their hands? It seems so. The correct hands washing technique is made by Professor John Oxford. He says you have to wash your hands while singing two verses of Happy Birthday to you. But while letting your children, or your husband, play in the dirt may well be ok, they still need to wash their hands after the toilet.
