Hange in milk bacterias and the effect on teenage girls

The essay should provide basic information on the medical and microbiological aspects of the disease (causative agent, symptoms, treatment, etc.) as well as the social aspect (e.g. socio-economic characteristics of those suffering from this disease, geographic distribution; historic perspective, etc)]. A paper should present the perspective/position of different nations/countries in regard to measures for preventing disease outbreaks (e.g. type of health care system, vaccination programs etc.) and compare those to WHO standards.

This paper needs to have some global learning aspect, which is the part of the geographic and historic perspective. Furthermore, hints for the topic is how the changes in bacteria in milk production are changing the girls (specifically teenage girls) hormones and this makes them menstruate at an earlier age, and many hormonal imbalances in their bodies.
