Anatomy, Physiology & Disease - Assignment Example A good example of communicable disease that poses a huge threat to public health include HIV/AIDS. This disease is easy to diagnose; the most common diagnosis is through blood tests. In essence, testing is done in order to identify the presence of antibodies created in the body in an effort to fight the HIV (Holland, Olsen and Florey, 2007). It is worth noting that the disease is caused by a virus known as Human immunodeficiency virus (HIV). Some of the signs and symptoms of HIV/AIDS according to Hall, Hall and Cockerell (2011) include weight loss, diarrhea, coughing, dermatitis, herpes, TB, unrelenting wounds, and abscesses. Prevention of HIV/AIDS depends on the mode of transmission. It can be transmitted through sexual intercourse, blood transfusion, and transmission from a pregnant mother to the unborn child. Prevention of the disease in relation to sexual transmission is achieved through the use of condoms and sex education. Blood ought to be screened thoroughly before transfusion to detect the presence of the disease. Pregnant mothers also ought to be tested and subsequent treatment given in case of presence of the disease (Ramaiah, 2008). Antiretroviral drugs are used to treat the disease. These drugs are taken on a daily basis in a bid to minimize the amount of the HIV virus in the body (Ramaiah, 2008). There are also post-exposure prophylaxis medications that are used for emergency treatments when an individual has been exposed to the virus (Hall, Hall and Cockerell, 2011). There is however no known cure for the disease. These medication are only used to reduce the amount of HIV in the body in order to allow the body fight infections. Epidemiological studies have proved that HIV is transmitted through three routes namely sexual transmission, exposure to contaminated blood, and mother to child transmission. The

Modular questions for vendor systems - Article Example Although both best of breed and integrated system are very different and have their own particular nuances, the two systems each have both advantages and disadvantages. Doctor John Fontanetta (2010) is an emergency room physician who makes a convincing case for best of breed. Although speaking for the ER staff, he points out that the clinic or hospital has normally spent many years developing the system to suit their particular specialty and/or purpose. Why throw that away for an entirely new system that may or may not be up to date and suited to the facility? Another compelling argument concerns the fast-spreading H1N1 influenza virus. Doctor Fontanetta reports one hospital and its best of breed vendor had treatment and hospitalization plans operational in less than a day! However, Jay Simmons, an informatics professional, opts for the integrated system (2011), stating that not only are operating costs are lowered but the system is more efficient, in that PMS and EHR are working together. Yet even he admits that a clinic might regret ridding itself of the existing PMS. Sabooniha (2012) accurately describes the different loose knit information systems in a healthcare facility (pharmacy, financial, care, etc.) as a group of islands. They know who each other is but none of them is connected. The resulting chaos can result in a number of disadvantages for the facility, including increased costs and redundancy among systems. The most important resulting problem is the loss of data reliability. Therefore, he states that integration of all these systems is imperative for the business to be more competitive. The factors one must consider, according to Sabooniha, are â€Å"Flexibility, Real time, Reliability, Reusability, Performance, Complexity, The Centers for Disease Control (2012) agrees with Sabooniha in stating that the integration of systems will enhance security of the systems and greatly curtail the infamous leaks of patient privacy.
