Communicable Disease Research: HIV
Introduction
Infectious diseases are defined as illnesses that can be transferred from one individual to another through contact or exposure. They typically are caused by bacteria or viruses and hence are spread when individuals are exposed to blood products, bites from insects, bodily fluids, and even air. A sum of infectious diseases has been diagnosed or discovered, but not all have treatments available. Furthermore, some have to be reported to the concerned departments of health and government agencies within their outbreak locality. It is critical to understand that four are communicable diseases among the first most common causes of death. Some typically affect individuals living in disaster-affected areas (CDC, n.d). Even so, most will prevail even in well-off communities whenever a single individual is exposed and knowingly or unknowingly infects others. For communicable diseases to be prevented, communities need to ensure that their respective environments are clean, use vaccines if available, and have their health workers train in early identification and treatment. So far, most healthcare systems can manage communicable diseases due to effective environmental health strategies. In this paper, a comprehensive discussion about the human immunodeficiency virus (HIV) is provided. Among the elements considered in the debate include causes, symptoms of the disease, transmission, how social determinants of health aid in developing the disease, and its epidemiological triangle.
HIV
The communicable disease is a virus that typically targets and affects a person's immunity, increasing their chances of acquiring other diseases. HIV can potentially progress to an advanced phase regarded as AIDS (CDC, n.d). Advances made in the medical arena have over time ensured that individuals living with the disease access high-quality care. This means that they rarely will see the development of AIDS because of the increased availability of management treatments. WHO experts hold that the disease is now manageable, and hence most people suffering from it can lead long and healthy lives. Research evidence shows that most nations around the globe sufficiently manage the disease, its prevalence rates still are quite high in the third-world nations (CDC, n.d). The virus typically attacks CD4 cells, T-cell types that function to detect infections in the body alongside anomalies in other cells. They also use the cells to create copies of themselves. As such, the virus destroys the cells and reduces the body's ability to combat other infections.
AIDS
It is worth noting that HIV is one of the few lifelong conditions, but treatments available and some strategies can obscure it from the transmission and also from progressing. As mentioned earlier, AIDS is a consequence of HIV, which manifests when the virus progresses to its advanced stages (CDC, n.d). Physician regard AIDS as a condition which comes about when the count of CD4 cells is lower than 200 per cubic millimeter. It can also be diagnosed if the patient displays signs of some opportunistic infections, cancer, or both. If an individual infected with HIV fa...
