Introduction
The development of any disease on any patients goes through a natural history that can be split into a series of stages for convenience of analysis, intervention and treatment. The primary goal of a healthcare service is to preserve, prevent as well as restoring human health when it is impaired with the aim of minimizing sufferings and deaths. The essential part of these goals are exemplified in the clinical term "prevention" that is divided into three stages for simplicity. The process of prevention comprises of several activities that are also referred as interventions and designed to reduce the risk and severity that are deemed threats to health. Researchers and the medicine experts have classified the concept of prevention into three distinct categories namely, primary, secondary and tertiary preventions.
Firsts, Primary preventions refers to an initiative set to prevent illness before they actually occur. At this level of prevention, physicians are concerned about preventing exposure of health hazards that cause harm or diereses to the human population (Corbel & Henry, 2011). In other words, primary preventions plays a role of preventing the onset of specific illness using health risk mechanism to by alter activities, components or exposures that can trigger chronic diseases as well as increasing resistance to the effects of exposure to a disease agent (Corbel & Henry, 2011). Second, secondary preventions concerns with the medical procedures that are applied detect pathological patients’ on HAT patients before to treatment is administered to control the illness progression. For example, screening procedures are applied on patient with HAT symptoms to detect the advancement of the disease (Corbel & Henry, 2011). Subsequently, early intervention are considered once the observed symptoms are confirmed. The primary purpose of the secondary prevention is to reduce the impact, severity of the diseases at its onset period. Lastly, tertiary prevention as an intervention that is applied to reduce the impacts on patients currently suffering From HAT. It is done to help victims manage long term impacts or complexity of the illness (Corbel & Henry, 2011).
Primary Prevention Strategies for HAT
As the aim of the primary prevention is to prevent the onset of the trypanosomiasis, the health stakeholders in DRC have suggested measures that focuses on minimizing contacts with the tsetse flies as there are there is no vaccine or drug for prophylaxis against HAT (Steinmann, Stone, Sutherland, Tanner, & Tediosi, 2015). First, Vector control is the chief approach in use as it is regularly employed with traps or screens in with insecticides and scents that are appealing the tsetse flies. The DRC local residence know regions that highly infested with tsetse flies and they have learnt to avoid (Steinmann, Stone, Sutherland, Tanner, & Tediosi, 2015). Also, the residence are advised to put on long-sleeved pants and shirts that are of heavy material and camouflage with the surrounding as the tsetse flies can bite through lightweight clo...
