HIV/AIDS was discovered in the 1980s by researchers including Dr. Robert Gallo and Dr. Luc Montagnier, though Gallo did not properly credit Montagnier. HIV slowly damages immune cells, leading to AIDS. It mutates easily, making a vaccine difficult to develop. There are two main types, HIV-1 and HIV-2. Africa has been severely impacted, with over 30 million deaths worldwide. Those most at risk are women, drug users, and those who do not use protection. It has significantly impacted societies and economies by killing many people and requiring substantial funding for treatment research.

Running head: SOUTH AFRICA HEALTH 1 2 SOUTH AFRICA HEALTH SYSTEM 3 SOUTH AFRICA HEALTH SYSTEM South Africa Health System Diamond DeWindt December 22, 2019 Author Note This paper was prepared for BHS380: Global Health and Health Policy, Session 2019NOV11FT- 1, Module 3, SLP 3 Assignment, taught by Dr. Michael Mucedola. South Africa Health System South Africa has a healthcare system which is structured at different levels. There are clinics, community health centers, and hospitals. The first level in the hospital structures are the clinics which treat the common needs of the people. It is these clinics that will refer someone further to the hospitals when one needs the further treatment. The clinics are either satellite or mobile clinics which are run by primary healthcare nurses. The community health centers are larger than the clinics and they have both nurses and doctors taking care of the patients. The last level of healthcare facilities are hospitals. The hospitals are for surgery, serious illnesses or emergency treatment that cannot be handled at the clinic levels. An individual can only go to the hospitals if they are referred by doctors in the clinics or in the case of an emergency. Basic healthcare is provided for free by the government through the healthcare services at the provincial level (Masquillier et al., 2015). There is also private healthcare insurance and those who get it receive tax benefits. There are several gaps that are present in the healthcare gaps in South Africa that have contributed to the rapid spread of the HIV pandemic. South Africa has one of the highest HIV epidemics in the world with over seven million people living with it (Masquillier et al., 2015). The spread of HIV has been caused by gaps which are there in dealing with healthcare awareness for marginalized groups. There are several demographics who do not get the sexual health care that they need such as sex workers, transgender women, gay men, as well as those who inject themselves with various drugs. The second gap that is there is lack of sufficient funds to get people to test for HIV. There is also lack of sufficient facilities to serve poor populations especially in slums to give them access to critical drugs such as ARVs. The healthcare system does not have sufficient capacity to deal with nutritional issues. One strategy that can be used to deal with the HIV/AIDs issue in South Africa is raising of public awareness through door to door campaigns especially in the slum areas. It is important for everyone to understand the importance of HIV/AIDS treatment and prevention. The local community needs also to realize that it is not good to have stigmatization of the minority groups such as gay men who do not get the healthcare which they deserve. All of this should be done to ensure that these groups of people are getting the care that they nee ...

Experts argue that focusing resources on diseases like HIV, malaria, and tuberculosis prevents neglected tropical diseases from being addressed. These neglected diseases affect over a billion people and could be treated cheaply with drugs costing less than 30p per person. However, health policies disproportionately target higher-profile diseases, ignoring neglected diseases that may cause greater burdens. This wastes an opportunity to eliminate scourges like sleeping sickness, elephantiasis, and river blindness.

1. The document discusses the concepts of health and disease. It defines health as a state of complete physical, mental and social well-being, not just the absence of disease. 2. Communicable diseases are caused by pathogens that can be transmitted between people. Examples include common colds, influenza, and tuberculosis. Non-communicable diseases like heart disease and cancer are not transmitted between people. 3. Health and disease exist on a continuum. Optimal health is at the top, with progressive illness and death at the bottom. A person's health fluctuates along this continuum based on lifestyle choices and environmental factors. Maintaining good health requires efforts to stay at the higher end of the continuum.

The document discusses different historical beliefs about the causes of disease: 1) Ancient peoples believed disease was caused by supernatural forces like gods, spirits or witchcraft. 2) In the 1800s, the "poisonous gas" belief held that diseases like malaria were caused by bad air from swamps. 3) The "germ theory" emerged in the late 1800s proposing that microorganisms cause infectious diseases. 4) Currently, the "agent-host-environment" model sees disease as the result of complex interactions among the infectious agent, the host, and environmental factors. Understanding this interplay is key to preventing communicable diseases.

Globalization has increased the spread of infectious diseases between countries. The HIV/AIDS pandemic demonstrated how a disease initially seen as limited can spread among the general population through blood transfusions and other means. Compromised immune systems also make populations vulnerable to additional diseases. Factors like global travel, medical practices, and environmental changes have contributed to the globalization of infectious diseases.

1. The overuse of antibiotics has led to an increase in Clostridium difficile infection (CDI) cases worldwide, making it a current pandemic. CDI disrupts the gut microbiome and allows the C. difficile bacteria to flourish, causing diarrhea and colitis. 2. CDI spreads easily through contaminated surfaces and facilities. C. difficile spores can survive for months on surfaces and are difficult to eradicate. Healthcare facilities are especially susceptible due to the proximity of patients. 3. Two lineages of C. difficile, FQR1 and FQR2, have developed resistance to antibiotics and have caused major outbreaks globally due to increased international

1. Are there relationships between personal (hygiene, eating habits, wearing of masks) social (public gatherings, proximity to one another) demographic (age, gender, education, racial ethnicity), and economic (occupation, level of education, annual income, home environment) factors and the spread, severity, and mortality rates of COVID patients worldwide? 2. Is there a difference in behaviour changes in people who have undergone cognitive behaviour therapy versus those who undergo pharmacologic intervention alone? 3. What is the difference in infection rates, pain intensity, inflammation, and restoration of functionality in people who have received prophylactic antibiotics and those who do not receive the prophylactic antibiotics during endodontic surgery? 4. What are nurses' perceptions towards patients who are non-adherent to the prescribed medications and are always complaining of deteriorating health? Question one : dependent and independent variables. The dependent variables in the first question are hygiene eating habits, wearing masks, public gatherings, proximity to one another, occupation, level of education, annual income and home environment (variables), COVID patients (Population) and spread, severity, and mortality rates. (testability). The independent variables include age, gender, and race. Why question 1? The end of 2019 set the beginning of what would become a life-changing experience for virtually everyone worldwide in the following one year. When COVID-19 first struck in Wuhan China, nobody speculated that the disease would later spread across the globe, killing millions of people and negatively impacting the livelihood of the affected. Other than the deaths that the disease has brought upon innocent people, their governments across the nations have implemented stringent policies to help curb the spread, such as national lockdowns, closure of schools and other institutions, curfews, and other strict rules, all intended to prevent the infection rates. These government intervention measures had a huge economic, social, and personal impact on people and led to other problems, including but not limited to mental health. Surprisingly, the disease was affecting different nations on varying intensities. For example, back in March 2020 COVID deaths in Italy were ranging above 700 on a daily basis while during the same time, there were very few cases and deaths in Africa (Di Lorenzo & Di Trolio, 2020; Onder et al., 2020). There were speculations that upon reaching Africa, COVID would lead to very high infection and mortality rates due to the poor healthcare systems and the relatively low economic status of most African countries. However, this turned out to be wrong as to date, the developed countries such as the USA, UK, and other European countries have the largest numbers of COVID cases and deaths (Bamgboye et al., 2020). The relatively low numbers of new cases and deaths in Africa is intriguing. This calls for res.
