In 1990 the Department of National Health and Population Development of South Africa launched a nationwide immunisation coverage campaign targetted mainly at measles. In order to measure the effect of the campaign on vaccination coverage rates for children pre- and post- campaign vaccination coverage surveys were performed using a modified EPI technique, stratified for race and urban/rural residence. The results in Natal/KwaZulu showed no significant changes in vaccination coverage rates as documented by Road-to-Health cards for any race, although the trend was towards a slight increase. The results bring into question the effectiveness of immunisation campaigns as a strategy for raising vaccination coverage levels, and having a sustained impact on the incidence of measles. Alternative strategies, such as the strengthening and expansion of existing primary health care services, and changes to the immunisation schedule for measles, should be considered. / Thesis (MMed.)-University of Natal, Durban, 1992.

South Africa has had one of the fastest growing HIV epidemics in the world and almost 30% of women attending public antenatal clinics (ANC) are currently infected with the virus. But as the epidemic is starting to level off and antiretroviral therapy (ART) is becoming increasingly available, few methods exist to determine the impact of ART or other interventions on the epidemic in South Africa. This thesis explores the epidemiology and dynamics of HIV infection and investigates the potential impact of ART. Methods Total and age-specific prevalence data are analysed in time and space and are used to investigate patterns of infection in men and women, urban and rural, and low and high risk populations. Dynamical models are developed to estimate incidence from age-specific prevalence and trends over time and are compared to laboratory-based estimates of recent HIV sero-conversion. Incidence is estimated in different populations in South Africa. A dynamical model is developed to estimate the impact of ART on the future course of the HIV epidemic. Results HIV prevalence varies geographically and by age, sex and race. The average female-tomale HIV prevalence ratio is 1.7 and prevalence peaks at an older age among men than women. The age at which prevalence peaks among women has increased from 23.0 to 26.5 years between 1995 and 2002. Four patterns of infection are identified: among pregnant women attending ANCs, among men and women in the general population, and among migrant workers. HIV incidence among ANC attendees peaked in the mid to late 1990s (at 6.6% per year nationally) with variation between provinces. Current estimates of HIV prevalence and incidence among the general population in South Africa (aged 15-49 year) are 18.8% and 2.4% per year, respectively. Age-specific incidence estimates from dynamical models and laboratory methods are in good agreement provided the window period for the laboratory method is increased. Over the next ten years the provision of ART could avert 1 to 1.5 million deaths depending on whether it is provided when the CD4 cell count falls to 200 or 350 cells/ul. By 2015 about 1.1 million people will be receiving ART but this will have little impact on the incidence of HIV and scaling up of prevention efforts remains urgent. Conclusions The thesis explores some of the determinants and patterns of HIV prevalence and incidence in South Africa in order to find better ways to manage the epidemic of HIV, monitor changes and evaluate progress in control efforts. In order to fight the epidemic we need to mobilize the best possible science in support of those people and communities affected by the epidemic. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2007.

Introduction: Inadequate water supply and sanitation adversely affects the health and socio-economic development of communities. Since 2003, more than 40 000 households in peri-urban and rural areas within eThekwini Municipality, South Africa, have been provided with urine diversion toilets, safe water and hygiene education. eThekwini Municipality have requested that these interventions be evaluated to monitor their effect on health outcomes. Aim: The aim of the study is to describe the baseline situation in respect of sanitation, safe water and hygiene behaviour in Intervention Areas in eThekwini Municipality and compare these to Control Areas. Methods: An observational analytic cross sectional study design was undertaken. A multi-stage sampling procedure was followed and six study areas were randomly selected. Three Intervention Areas (urine diversion toilets) were matched with three Control Areas (no urine diversion toilets). A total of 1337 households, comprising of 7219 individuals, were included in the study. A Household Questionnaire a and an Observational Protocolb was administered by fieldworkers. Data was entered onto a custom designed EpiData database, processed and analysed using SPSS version 13. Results: The baseline characteristics revealed that Intervention and Control areas were very similar other than the provision of urine diversion toilets, safe water and hygiene education in the Intervention area. The Intervention area scored higher than the Control area (2.31 vs. 1.64) with regard to having a cleaner toilet, with no flies, no smells, having hand-washing facilities and soap provided close to the toilet. Some of the collected data from questionnaire responses were not consistent with the fieldworkers observations. It was reported that 642 households in the Control and 621 in the Intervention areas washed their hands with soap, whilst only 396 households in the Control and 309 in the Intervention areas were observed to have washed their hands with soap. Conclusion: Households in the Control area are at a greater risk of developing diarrhoeal and other related diseases. The provision of safe water, urine diversion toilets and hygiene education in the Intervention area has proved to be successful. Recommendations: eThekwini municipality must expand the package of services c to the Control areas. Sustainable hygiene education programmes must continue to be implemented and be evaluated over time.

Human Immunodeficiency Virus (HIV) infection and Auto-Immune Deficiency Syndrome (AIDS) have spread globally during the past twenty-eight years and 67% of people living with HIV live in sub-Saharan Africa. HIV and AIDS are now the leading cause of death in this region. Worldwide, it is the fourth biggest killer. Nurses in health institutions in South Africa face challenges as result of increased number of very sick and terminally ill patients who are admitted to the hospital due to HIV and AIDS epidemics. Workloads have increased with no concomitant increase in number of staff to care for the patients. Aim: This study aims to identify dynamics of care of professional patients with HIV and AIDS by nurses and make recommendations that will deal with these problems. Methods: A qualitative study was conducted with the study population drawn from professional nurses who were involved in the care of patients with HIV and AIDS in the medical wards at Ngwelezana Hospital for at least five years. One focus group discussion was also conducted. The sample was selected purposively. Results: The study revealed many issues affecting the care nurses gave to patients with HIV and AIDS and the personal challenges (physical and emotional) they faced in the course of their work. Amongst these are contextual challenges which pertained mainly to health system issues- lack of institutional support and incentives, heavy workload with concomitant increase in number of patients attended to by nurses, training needs of nurses and multidisciplinary team work. Nurses had to deal with personal challenges such as helplessness, frustration, anger, death anxiety, physical and emotional stress. However, there were positive experiences such as empathy and self-actualisation in being able to care for terminally ill patients and seeing some of them get better with treatment. Recommendations: These include the need to address the training needs of nurses about management of HIV and AIDS, institutional support for nurses, critical incident debriefing and community awareness. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2010.

BACKGROUND : Many professional nurses have left the employment to work in developed countries. Quality patient care is declining because the few PNs that are rendering care have limited expertise. Literature review showed that nurse managers have a role to play in retention of staff. PURPOSE : The study aims to analyze the leadership styles and organizational factors toward the retention of professional nurses working in public health facilities. POPULATION : Professional nurses in four public hospitals, four union managers, twelve professional nurses working abroad and representative from SANe. A total of 188 participated in the study which formed part of the 70% of the sample. DESIGN : A Case study design which included both quantitative and qualitative approaches. Observations in the wards and document analysis were done guided by a case protocol. INSTRUMENTS : Revised Nursing Work Index and Revised Conditions of work effectiveness was administered among the professional nurse and chief professional nurses. Chief nursing service managers and union managers were interviewed using interview guides. Focus groups among professional nurses who had overseas experiences were conducted. Reliability was maintained by having a Cronbachs alpha of above 0.70 in all variables except leadership. RESULTS : Cases presented differently in all aspects, except Case C who was consistent in all the variables. The professional nurses in Case C viewed their CNSM as being visible and accessible. Case A and B were similar in terms of the organizational factors. All CNSM verbalized that they were willing to send PNs for educational programmes but the DOH policy was allowing nurses to work anywhere in the province. PNs had little access to resources on time to do tasks and paperwork as compared to access to support and opportunity.CONCLUSION : PNs are willing to stay in their organizations provided they will be given educational and promotional opportunities. There was a relationship between organizational factors and retention. Leadership factors showed a weak negative relationship with other variables. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2009.
