You can answer this question by observing the status of third world countries. Third world countries are usually underdeveloped economically and technologically. There are more homeless people and more incidences of poverty than in fully developed countries. Even some of the living conditions are unhealthy and unsafe, especially in the squatters’ areas. Here are specific reasons why parasitism is more common in their world countries.
A sizable chunk of the population lives in squatters’ areas where environmental sanitation is poor, and the surroundings harbor the parasites. Parasites reside in warm, moist soil and dirty surroundings. The poor population does not have the capacity to go to school so they are not aware of the mode of transmission of parasitic agents. Being unaware of these, they would not take precautions. Those who were found out to be infected could not go for treatment because of financial constraints. The lucky ones who were able to, sometimes lack the financial capacity to buy needed medicine, or when they have money, the medicine is scarce. There are not enough health centers and health professionals to conduct efficient health services.
In third world countries, sometimes the rural areas are unattended because of the lack of personnel and medical equipment. Due to several people with parasitism, re-infection occurs and even autoinfection. Parasitism keeps recurring because of the inability to live in clean, comfortable, and healthy environment. The presence of secondary hosts are more common in third world countries because families tend to place their poultry and pigpen near their abode because of lack of space and ignorance of the diseases and parasites these animals could pass on to humans.
In, third world countries , brain drain usually occurs because skilled professionals like doctors, nurses, medical technologists and physical therapists are going abroad to earn and at least live a comfortable life. This leaves the country lacking in health-allied personnel. Solving this problem by increasing the minimum wages of these professionals would help a lot in solving this problem. Third world countries have less updated technology so everything moves in a slow motion. Delivery of health care services is one of them, resulting to sickness, parasitism among one of them.
If there is a sustainable, health program that would have goals of efficient delivery of goods and services and sufficient campaigns to create public awareness, then the perennial problem of parasitism would definitely be resolved, and slowly be controlled and eventually eradicated. Fully developed countries have preventive measures in place to readily correct the problem.
