I mentioned earlier that bad luck had some part to play in the production of colitis disease. I was referring to the bad luck of eating food that was infected or of infecting oneself through what seems to be good food. An overlooked factor, however, is that water is used to clean dishes. If that water is infected it may carry with it the germs of typhoid or paratyphoid. Food may also carry some of the filterable viruses from dishes. The unclean hands of diseased food-handlers can carry the parasites of ameba or tape worms.
Certainly all these can be classified under the heading of bad luck and conditions over which the average person has no control. If, of course, one is going to journey into an area such as some parts of the world where typhoid is known to exist or where dysentery is prevalent, it is the height of prudence to be vaccinated against typhoid, cholera, etc. Complete protection against amebic dysentery may be obtained by the steady use of anti-amebic substances like Milibis which can be taken in a prophylactic manner in much the same way as one takes anti-malarial medicines if they feel they may be exposed to malarial microbes.
