The largest proportion of contaminated phones was in Birmingham (41%) while Londoners were caught with the highest proportion of E. coli present on hands (28%). However, actual levels of bacteria increased the further north the scientists went, the dirtiest city being Glasgow, where average bacterial levels on phones and hands were found to be nine times higher than in Brighton, reinforcing a North/South divide. The scientists also found those who had bacteria on their hands were three times as likely to have bacteria on their phone.
Dr Ron Cutler, of Queen Mary, University of London, said: "Our analysis revealed some interesting results from around the UK. While some cities did much better than others, the fact that E. coli was present on phones and hands in every location shows this is a nationwide problem. People may claim they wash their hands regularly but the science shows otherwise."
Faecal bacteria can survive on hands and surfaces for hours at a time, especially in warmer temperatures away from sunlight; it is easily transferred by touch to door handles, food and even mobile phones. From there, the germs can be picked up by other people. Every year, 3.5m children under the age of five are killed by pneumonia and diarrhoeal diseases and the simple action of washing hands with soap is one of the most effective ways of preventing these illnesses. In developed countries, handwashing with soap helps to prevent the spread of viral infections, such as norovirus, rotavirus and influenza.
Global Handwashing Day - which is held on October 15 every year - aims to transform the action of washing hands with soap into an automatic behaviour, deeply set in our daily lives. Initiatives and events to promote the practice in homes, schools, workplaces and communit
