Infections are spread through the water, air and people. The water spread infections are like cholera, diarrhea and viral diseases. These diseases are spread through the micro organisms that are present in the water. The next one is the diseases that is spread through air, when a person coughs or sneezes without closing their mouth or nose the infection from one person spread to other person. The common cold spread through the people in this way only. So the person who suffers from the cold and should cover them properly so that other person don’t get infected by them, there are people who have he infection they have to be very careful. Most of the people get diseases through infection only in the undeveloped countries people are not clean and they don’t keep their surroundings and they don’t have use proper cleaned toilets, this the reason why they get soon the diseases and there is no medical facilities in their countries. So all the people should be taught to keep themselves and their living place clean so that they could free from the diseases,  The developed countries should come forward to help undeveloped countries and developing countries o be healthy. Thus the control of infection should be controlled by the government.
