In analaysing the benefits of sanitation, cases of diarrhoea are typically taken as an indicator that better sanitation is leading to better health.
However, this is not applicable in a cold climate as diarrheal cases tend to be seasonal and prevalant in summer. In winter, better sanitaiton might instead prevent urinray tract infections/influenza from not having to use facilities in the cold.
I wish to monitor the effects of good sanitaiton in a schools context in a colder climate i.e. are the bacteria typically used as indicators inhibited by the cold and bad sanitation in the winter is not such a big deal? or does good sanitaiton in general lead to better health? are the effects of poor sanitaiton in winter felt in the winter or in the summer when waste defrosts and spreads to water sources?
Its all just many random thoughts at the moment but if anyone has any ideas they would like to contribute they would be much appreciated.
