TheUse of the Epidemiological Triangle in Preventing the Spread of TB

Epidemiologicaltriangle refers to a model developed to facilitate the study ofhealth problems. It is mainly used in the study of infectiousdiseases and their spread in the community (Public Health Agency ofCanada, 2014). In the present case study, Debbie, who is aBSN-prepared community health care nurse should apply the concepts ofthe epidemiological triangle in preventing the spread of TB in thecommunity. In essence, the epidemiological triangle helps in theprevention of diseases by breaking the link between the host, theenvironment, and the agent. In this case, the agent is Mycobacteriumtuberculosis, the host is the Hispanic immigrants, while theenvironment is the workplace where these immigrants work as well astheir residential areas.

SinceDebbie has already identified the agent, host, and the environment,the objective of the next courses of action should be to break therelationship between the three factors. There are three major stepsthat can break this relationship. First, Debbie should mobile thelocal health care stakeholders to give medication to the sickimmigrants immediately in order to kill the agent and prevent itstransmission to the healthy population (Mayo Foundation, 2014).Secondly, Debbie should advocate for the vaccination of the healthyresidents and workmates of the Hispanic immigrants from contractingthe agent (Health-Wise Incorporation, 2014). Third, the host shouldbe educated in the effective methods of preventing the spread of TB,such as avoiding overcrowded places and applying protective measureswhen assisting the sick people. Lastly, the sick people withresistant Mycobacterium tuberculosis should be isolated immediatelyand given medication until they get full recovery.

TheGeographical information system is an effective tool that Debbie canuse to study the relationship between the spread of TB and theenvironment. Some of the environmental factors that should beconsidered in this case include location, abundance of thedisease-causing agent, and vector distribution (Srinath, 2013). Thiswill facilitate the process of surveillance as well as thedecision-making. In conclusion, epidemiological triangle is aneffective tool that helps the health care professionals in studyingthe spread of infectious diseases, thus facilitating the process ofpreventing their spread.
