Furthermore, we have learned established facts about how these diseases are transmitted, so we have become more knowledgeable in using methods based on knowledge derived from scientific research. It is true that building hospitals and equipping them with what is necessary for nursing and treating patients is commendable and necessary, but it does not cut off the root of the problem we are dealing with. If other precautions and measures are not taken, then no matter how many hospitals we build and how many patients we treat, they will have no effect on the occurrence of diseases like those we have mentioned. Since prevention is better than cure, it is imperative that we address the root of the mentioned ailments and evils and follow a correct plan based on knowledge of the natural history of infectious agents and the principles and conditions under which prevalent diseases in the country are transmitted and spread by contagion from place to place in all countries. This is the agreement on this principle. If we turn our attention to all the villages, we find that the conditions there are conducive to the life of the unhealthy bodies that cause diseases such as bilharzia and schistosomiasis, the spread of which depends on the condition of the soil, water, and unhealthy environment, as in these countries. Health reforms in Egypt did not begin until recently, and most of them have taken place in large cities and places intended for health and well-being. In general, they have been sufficient to achieve the goal and ensure the introduction of these reforms to the villages in a moderate manner. The absence of health intermediaries in the villages is the cause that must be treated, even if only for economic considerations. Significant progress in preventing important infectious diseases and protecting the country from them will not be achieved until we undertake this in the villages and take some steps in this direction. The villages and their surroundings are built in such a way that they cannot be made to a standard of health that Westerners would praise. The houses are nothing more than heaps of poorly constructed, poorly ventilated mud walls, devoid of any provision for water. People live in them, along with their livestock, and they draw water from canals exposed to all kinds of infection and contamination. Ponds are abundant everywhere due to the proximity of water, which
