GEOGRAPHY AND STATISTICS

E-coli is found in food, in the intestines of animals and people and in our environment.  E-coli is considRubella was recorded as early as the eighteenth century and was formally recorded as a separate disease in 1881. There have been epidemics and pandemics through the 1940's and 1960's but due to the introduction of a live vaccine in 1969 and an increase in vaccinations rubella has been eliminated in some countries. There are some populations within the UK that are not vaccinated and therefore prone to being infected by rubella but most cases arise in countries where the vaccine is not as accessible within the developing world.
