1.Describe the chosen communicable disease, including causes, symptoms, mode of transmission, complications, treatment, and the demographic of interest (mortality, morbidity, incidence, and prevalence). Is this a reportable disease? If so, provide details about reporting time, whom to report to, etc. 2.Describe the social determinants of health and explain how those factors contribute to the development of this disease

 Communicable Disease This will describe the communicable disease, Human immunodeficiency virus, commonly known as HIV is one of the deadliest communicable disease. This write up will describe the disease thoroughly including causes, symptoms, mode of transmission, complications, treatment, demographic of interest, mortality, morbidity, incidence, and prevalence of HIV. Health determinants will also be described in the areas of lifestyle, genetics, environment, and social. The epidemiologic triangle will cover the host, agent, and environmental factors of HIV. Lastly, the role of the community health nurse and one national organization that contributes to reducing the impact of HIV will be discussed. Human immunodeficiency virus (HIV) is an immunodeficiency disorder resulting in defective immune functioning. CD4+or T-helper/inducer lymphocytes act as a mediator between antigen-presenting cells and other immune cells, such as B cells and other T cells. A defective cell-mediated immunity is the hallmark of an HIV infection, especially a decrease in their CD4+count. The retroviruses, HIV type 1 and HIV type 2 that primarily infect CD4+ lymphocytes and macrophages are the cause of HIV infection. HIV is a reportable disease, therefore any patient coming to the hospital needs to be counselled on reporting the disease to the doctors and staffs involved in caring. Patients have the rights to not reveal about the disease to any one they wish to, but appropriate counselling needs to be given
