The rural environment, which is usually characterized by under development and poor public facilities, in most part of the world has been discovered to be the most vulnerable to diseases and its outbreaks. This is as a result of several factors which include and may not be limited to poor hygiene, unsafe food processing/preservation methods, inadequate or ineffective healthcare systems, poor water supply networks, illiteracy, and sometimes traditional ceremonial practices(especially in Africa).  Such factors have persisted over time due to the fact that much capital is required for improvement in these regards. Disease transmission and control is one of the major challenges been faced by rural communities. Modern Science(read more about modern medicine here) have been put in place in many quarters to reduce transmissions; these are by ways of identifying disease causing organisms and environments or conditions that favour their survival. Some factors that affect the growth and transmission of diseases in the rural areas coupled with the ways out are discussed below.

Food Processing and Preservation Methods

This is a very important factor that affects disease(read more about diseases here) outbreak. Usually, rural areas lack modern and improved facilities for food processing and preservation, thus consumed food are not properly processed most times. For example, pasteurization is aimed at destroying lactic acid bacteria which would cause milk sourness and for keeping down microbial numbers which are capable of causing disease from the milk products. Other food require high heat processes as high as 170°c to completely destroy pathogens present in them. But contrary to recommended procedures, it is common to note that these are not carried out.

Villagers tend to hurriedly prepare food, without ensuring the safety of the food. It is not advisable that cheese from cattle be eaten without been properly cooked, irrespective of how healthy the animal may look. Campylobacter which occur mainly in poultry must be subjected to high temperature before they can be eradicated. Also, since organisms causing disease thrive at specific optimum temperature, lack of refrigeration and cold temperature enhancer machines would have allowed organisms alter the safety of food.

The uncooked or partially cooked meal and animal products are majorly the causes of high level diarrhea. About  1.8 million persons die each year from food and water related diarrhea with a larger percentage occurring in the rural areas.

Crop Harvesting Process

Another way through which disease causing organisms get into food and ultimately into a human host are from the farm. During period of harvest, the harvested produce such as fruits and vegetables are exposed to the environments (read about how the environment affect our health here) which have not been sterilized. For instance, vegetables harvested are kept on poorly cleaned sacks might have harboured  some micro-organisms such as the Entamoeba histolytica which gets into vegetables and is eaten, causing severe diarrhea. It is prop, as a means of control, that central refrigerator storages at least, be provided for rural dwellers, where they can store up food.

Water supply networks

Some diseases are water borne. Safe water fit for drinking and general use is usually not available and the main source of water supply is from streams and rivers, some of which are a stagnant pool of water containing a large amount of harmful aquatic organisms. This shows the extent at which water supply is a real challenge to the health people living in the rural areas. Hospital transfer cases in the urban areas are usually those like cholera, which majorly result from unsafe water consumption. A more terrible disease associated with water is the onchocerciasis commonly known as river blindness which has its origin in water.  To control the transmission of these water-borne diseases, rural communities should be provided with pipe borne water or bore holes to wipe off infections. Non flowing rivers and streams should be treated regularly to stop breeding of harmful disease causing insects


Until recently, when schools are been built in rural areas, majority of the populace are illiterates that are not knowledgeable in health standards and hazards as well. They live by chance, without knowing that certain actions pose dire health repercussions. For example, many rural settings are known to have a common source of water for drinking and laundry purposes; sometimes it may even serve as a lavatory. This is due to ignorance (read more about no excuse for ignorance here), and it may lead to serious disease outbreaks which they are equally unable to manage. On the instances of disease outbreak such as tuberculosis where quarantine and isolation of patients may be necessary, the disease tends to spread faster because the individuals are not aware that it is communicable and easily spread from persons to persons. Thus, to prevent disease outbreaks, there must be increased awareness of the people on disease outbreaks, their prevention, treatments and/or management. This would help reduce number of victims and the death rate. The public health worker would be more useful in these communities to educate and prepare people in case of future outbreaks.

Poor Hygiene

The personal  hygiene (read more about personal hygiene here) in rural areas are very poor and there leaves a lot to be improved upon. Restaurants and eateries usually do not meet sanitation standards as materials and utensils may be too old and unhygienic. Typhoid fever caused by salmonella may be due to poor hygiene in food preparation, whereby food is contaminated with infected faeces. This is likely to occur in places where source of water is also passage way for animal wastes.

To get rid of harmful organisms, handkerchiefs and towels should be properly washed and sun-dried. Food handlers should be encouraged to adopt modern hygienic food preparation rules and etiquettes such as use of hair covers, aprons, and nose masks when necessary. Wastes shouldn’t be disposed close to food area, while refuse should be burnt immediately.

Inadequate and Ineffective Healthcare System

Advances in medical science has made available (read more on the emergence of modern medicine), vaccines and series of measures to curb pathogenic infections in humans have also been introduced. This has helped to bring some disease infections such as polio and meningitis to the minimum. But then, this seems to be a contrast with the rural condition as there are no facilities for such immunization especially for children between 0-6years. This leaves them susceptible for a greater part of their lives. Hence the need for develop the healthcare system in rural areas. There is need for adequate staffing of qualified and experienced health workers. Current drugs and equipments should be provided as well.

In conclusion, the sum total of the health status of the rural community would determine in a large way, the economic buoyancy of the area which consequently affects the world at large.
