The role of governments in the fight against HIV/AIDS in Southern Africa: a case study of South Africa.

Mngomezulu, Skhumbuzo Julius January 2005 (has links)
HIV/AIDS is a deadly disease that needs to be addressed with immediate effect before serious damage can occur. Because the government has a responsibility over the health of its citizens, everybody expects the government to take a lead in the fight against this epidemic and from the look of things the government's strategies are not making the desired impact on the epidemic. The author attempted to highlight that the South African government has not played a satisfactory role in the fight against this pandemic, which threatens to alter history to a degree not seen in the world.

Follow-up care of infants born in a prevention of mother-to-child transmission programme in an urban hospital in KwaZulu-Natal, South Africa.

Chetty, Terusha. January 2011 (has links)
Introduction. The Human Immunodeficiency Virus (HIV) is the main contributor to rising child mortality in South Africa. Although prevention of mother-to-child transmission programmes have been implemented in the country, little is known about the clinical and loss to follow-up outcomes of infants born to HIV-infected women attending these programmes. Purpose. The purpose of the study was to describe the clinical and loss to follow-up outcomes of HIV-exposed infants whose mothers had received antiretroviral therapy or prophylaxis during their pregnancy at the Prevention of Mother-to-Child Transmission programme at McCord Hospital. Furthermore, maternal socio-demographic characteristics associated with these outcomes were determined. Methods. An observational retrospective cohort study design was used. The study population consisted of infants whose mothers had received antiretroviral prophylaxis or therapy at McCord Hospital, and were delivered at McCord Hospital, and/or were brought back to McCord Hospital, following delivery from 1 May 2008 to 31 May 2009. Results. Data on 265 infants was analysed. Of the 220 infants who were tested, the HIV transmission risk was 2.7% (n=6; 95% Cl: 1.0% to 5.8%) at 6 weeks of age. Overall, 40.4% of infants in the cohort were lost to follow-up (n=105, 95% Cl: 34.4 to 46.6). In the multivariable model (n=253), late booking for first antenatal visit at or after 28 weeks of gestation (adjusted hazard ratio (AHR) 2.3; 95% Cl: 1.0 to 5.1, p=0.044) was a risk factor for loss to follow-up. Compared to having an emergency caesarean section, having an elective caesarean section (AHR 1.9; 95% Cl: 1.1 to 3.5) or normal vaginal delivery (AHR 2.5; 95% Cl: 1.4 to 4.5) was significantly associated with loss to follow-up of infants. Discussion. The substantial attrition of infants born to HIV-infected mothers in the Prevention of Mother-to-Child Transmission programme at McCord Hospital undermined the goals of the programme, and underestimated the effect of infectious disease morbidity, mortality and HIV transmission risk associated with these infants. Recommendations. Counselling mothers on the health benefits to their HIV-exposed infants of attending the follow-up clinic and tracing of infants who have been lost to follow-up is vital to the operational effectiveness of the Prevention of Mother-to-Child Transmission programme at McCord Hospital. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2011.

An investigation into joint HIV and TB epidemics in South Africa

Pretorius, Carel Diederik 12 1900 (has links)
Thesis (PhD (Physics))--Stellenbosch University, 2009. / ENGLISH ABSTRACT: This dissertation investigates certain key aspects of mathematical modeling of HIV and TB epidemics in South Africa with particular emphasis on data from a single well-studied community. Data collected over a period of 15 years (1994 to 2009) in Masiphumelele, a township near Cape Town, South Africa are used to develop a community-level mathematical model of the local HIV-TB epidemic. The population is divided into six compartments and a system of di®erential equations is derived to describe the spread of the dual epidemic. Our numerical results suggest that increased access to antiretroviral therapy (ART) could decrease not only the HIV prevalence, but also the TB noti¯cation rate. We present a modeling framework for studying the statistical properties of °uctuations in models of any population of a similar size. Viewing the epidemic as a jump process, the method entails an expansion of a master equation in a small parameter; in this case in inverse powers of the square root of the population size. We derive two-time correlation functions to study the correlation between di®erent types of active TB events, and show how a temporal element could be added to the de¯nition of TB clusters, which are currently de¯ned solely by DNA type. We add age structure to the HIV-TB model in order to investigate the demographical impact of HIV-TB epidemics. Our analysis suggests that, contrary to general belief, HIV-positive cases are not making a substantial contribution to the spread of TB in Masiphumelele. We develop an age-structured model of the HIV-TB epidemic at a national level in order to study the potential impact of a proposed universal test and treat program for HIV on dual HIV-TB epidemics. Our simulations show that generalized ART could signi¯cantly reduce the TB noti¯cation rate and the TB-related mortality rate in the short term. The timescale of the impact of ART on HIV prevalence is likely to be longer. We study the potential impact of more conventional control measures against HIV. Guidance for possible future and/or additional interventions emerge naturally from the results. We advocate a reduction in intergenerational sex, based on our ¯nding that 1.5-2.5 standard deviation in the age di®erence between sexual partners is necessary to create and sustain a major HIV epidemic. A simulation framework is developed to help quantify variance in age-structured epidemic models. The expansion technique is generalized to derive a Fokker-Planck equation. Directions for future work, particularly in terms of developing methods to model °uctuations and validate mixing assumptions in epidemiological models, are identi¯ed. / AFRIKAANSE OPSOMMING: Hierdie proefskrif ondersoek aspekte van die wiskundige modelering van HIV en TB epi- demies in Suid Afrika en fokus ook op 'n spesi¯eke gemeenskap. Data wat oor 'n periode van 15 jaar ingesamel is (1994 tot 2009) in Masiphumelele, 'n woonbuurt naby Kaapstad, Suid Afrika word gebruik om 'n wiskundige model te skep wat HIV-TB in die gemeen- skap modeleer. Die populasie word in ses kompartemente verdeel en 'n stel di®erensiaal vergelykings word afgelei om die verspreiding van di¶e epidemies te ondersoek. Ons nu- meriese resultate toon aan dat verhoogde toegang tot antiretrovirale behandeling (ARB) die potensiaal het om HIV prevalensie die TB koers beduidend te laat daal. Ons ontwikkel 'n raamwerk waarmee die statistiese eienskappe van °uktuasies ondersoek kan word in enige populasie van dieselfde grootte. Die metode ontwikkel 'n meester vergelyking vir die on- derliggende geboorte-dood stogastiese proses en brei dit uit in terme van 'n klein parameter; in di¶e geval in inverse magte van die vierkantswortel van die populasie grootte. Die twee-tyd korrelasie funksies word afgelei, en word gebruik om die korrelasie tussen verskillende tipes van TB episodes te bestudeer, asook om te wys hoe 'n tydselement aan die de¯nisie van TB groeperings gegee kan word. Di¶e word tans slegs d.m.v DNA tipe geklassi¯seer. Ouderdom- struktuur word aan die model toegevoeg om die demogra¯ese impak van HIV-TB epidemies te bestudeer. Ons analise toon aan dat, anders as wat algemeen aanvaar word, maak HIV- positiewe gevalle nie 'n groot bydrae tot die verspreiding van TB in Masiphumelele nie. Ons ontwikkel 'n ouderdom-gestruktureerde model van HIV-TB op nasionale vlak en gebruik die model om die potensiÄele impak van 'n universele toets- en behandel strategie op die HIV-TB epidemies te ondersoek. Ons simulasies toon aan dat algemene ARB waarskynlik 'n groot impak op die TB aanmeldings koers asook die TB-verwante mortaliteits koers kan h^e binne 'n relatiewe kort tydperk. Die impak op HIV prevalensie sal eers oor 'n veel langer periode duidelik word. Ons ondersoek ook die moontlikheid van meer konvensionele beheermaa- treels. Ons ontmoedig tussengenerasie seksuale omgang, gegrond op ons bevinding dat 'n standaard afwyking van 1.5-2.5 in die ouderdoms verskil tussen seksuele vennote, nodig is om 'n HIV epidemie van stapel te stuur en te onderhou. Ons ontwikkel 'n simulasie raamwerk om variansie in ouderdomgestruktureerde modelle te benader. Die uitbreidingstegniek word veralgemeen om 'n Fokker-Planck vergelyking af te lei. Ons identi¯seer probleme in die on- twikkeling van metodes om interaksie patrone en °uktuasies te modeleer in epidemiologiese modelle as opgawe vir toekomstige werk.

Towards a more comprehensive framework to estimating the indirect costs of HIV/AIDS in South Africa.

Andemariam, Ruth Tekle January 2004 (has links)
This study proposed a modification of the traditional cost-of-illness approach. It considered additional indirect cost parameters that yield a comprehensive cost structure for human capital at a micro level. Although HIV/AIDS is an epidemiological problem, it has enormous direct and indirect economic costs. Arguably, the most important cost associated with HIV/AIDS results from the high rates of morbidity and mortality among working age adults, the vast majority of those infected. These are essentially losses in an economy's existing stock and potential accumulation of human capital, implying lower levels of labor productivity and eventually loss of labor. These impacts are accounted for in existing macroeconomic and microeconomic impact studies. Indirect costs, such as forgone earnings due to illness, are included whereas forgone earnings of caregivers in the household are unaccounted for.

"Indoda" in the dawn of the HIV/AIDS epidemic: a study of masculine ideals, behaviors and practices among black heterosexual men living with HIV

Mthombeni, Nomaswazi Mandisa January 2017 (has links)
A thesis submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for Masters degree in Sociology March 2016 / Following a qualitative approach and using diaries and the anthropological tool of ethnography, the study engaged black heterosexual men living with HIV to explore and describe their masculine ideals, values and behaviors in the dawn of the HIV epidemic. The findings revealed that the fabric that made “Indoda” varied and changed over time but to be Indoda , a man had to have one’s own family and consequently be the head of the family “Intloko yo Muzi”.Indoda was also detailed as someone who was “iQhawe”,a warrior who fought many battles of invulnerability and endured hardships. The findings suggested that although participants strove to attain these specifications, they were also restricted and burdened by them; especially those who were under varying degrees of pressure as a result of the different social, economic and political transitions that were taking place. HIV was seen as a threat to the constructions of hegemonic masculine ideals and thus exposed a budding crisis of masculinity that men in this context were confronted with. While HIV seemed to alter ones identity for some of the participants, other participants revealed that HIV did not change their lives in anyway. Among these participants, multiple relationships with ‘roll ons’; secrets and low condom use were rife. The other group of men who differentiated themselves from those who were HIV negative challenged the dominant notions of masculinities and reconstructed their masculinities in more positive ways. In this way, these men inhabited a subjective position of agency by taking control of their lives and accepting and driving their Z3. The study concluded that masculine norms behaviors and values are fluid and it is through continuously engaging in critical examination of the discourses that construct masculinity that new constructions of what it means to be a man can emerge. / MT 2018

Clinical outcomes of antiretroviral therapy patients following the implementation of new eligibility criteria in Sekhukhune District

Makgato, Valerie Kedibone January 2018 (has links)
Thesis (MPH.) --University of Limpopo, 2018 / Background: The prevalence of HIV in South Africa has increased largely due to the combined effect of new infections, and a successfully expanded antiretroviral treatment programme, which has increased survival among people living with HIV. As the up-scaling of patients on ART has been increased, the aim of the current study was to investigate the variations of the clinical outcomes between patients initiated with CD4 < 350 and of those above 350 after the implementation of the new eligibility criteria for ARV therapy. Methods The current study used quantitative approach to retrospectively review a total of 488 records of adult patient who were registered in health facilities which were purposefully sampled from Sekhukhune District of Limpopo Province. SPSS version 23.0 was used to analyse data. Results Approximately 60% of the patients initiated on ART were having CD4 count <350 and male patients were more at 74% as compared to females at 54.7%. Patients who started ART with a baseline CD4 >350 had a high rate of lost to follow up within 3 months after start of ART at 15% than those with a baseline CD4 <350 at 10.2. More patients were lost to follow-up shortly after starting treatment at 3 months at an average of 13.8% in both CD4 counts. Majority of patients retained in care were those who started ART treatment with a baseline CD4<350 at 87.4%. Viral load completion rate at 12 months was higher than that of 6 months, at 86.8 and 80.5 respectively. Patients with a baseline CD4 >350 suppressed more than those who started ART with a baseline CD4 <350 at both 6 and 12 months at >90% suppression rate. Lastly, most of the patients died within 3 months of ART treatment and had a baseline CD4 < 350 than at 2.4% those with a baseline CD4 >350 at 0.6%. Conclusions The implementation of the new eligibility criteria of ART initiation improves the clinical outcome of patients on ART. There are still patients that are missed to be monitored viral load bloods which play a key role in determining the clinical outcomes of patients. Clinicians and nurses should adhere to the recommended time frames for monitoring of ART patients to improve clinical outcomes.

Knowledge and attitudes of women regarding mother-to-child transmission of HIV infection in the Ehlanzeni District, Mpumalanga Province, South Africa

Sechabe, Ednah Virginia January 2011 (has links)
Thesis (M. Cur.) --University of Limpopo, 2011. / HIV/AIDS is one of the major challenges facing South Africa today. Over 5.5 million people are infected with HIV and the majority of these infections are in the reproductive age group. Since the start of the epidemic, over 12.2 million women worldwide have been infected with HIV (WHO, 2000:10). The risk of women contracting HIV is rising globally. HIV seems to be a major cause of infant mortality. It is estimated that approximately 55% of women in South Africa are HIV-positive (National Department of Health, 2007:7). It is, therefore, important that knowledge and attitudes of women regarding mother-to-child transmission (MTCT) of HIV infection are explored to reduce the high infant mortality rate and the incidence of MTCT of HIV infections, and to develop preventive programmes on HIV and AIDS. In view of these considerations, the objectives of this study were to explore and describe the knowledge and attitudes of women with regard to MTCT of HIV infection and to provide guidelines for the prevention of MTCT of HIV infection. The study was conducted in the rural area of the Ehlanzeni District in the Mpumalanga Province, South Africa at Bourke’s Luck and Elandsfontein clinics. An explorative, descriptive, qualitative research design that is contextual in nature was used. The population consisted of all pregnant women and those in pueperium between 25-40 years of age. Non-probability purposive sampling was used. Participants were selected according to inclusion criteria. Data were collected using semi-structured interviews. The research findings revealed that some participants had knowledge and understanding regarding MTCT of HIV infection while others lacked knowledge and understanding which could impact on MTCT of HIV infection.

The socio-economic impact of HIV and AIDS on community development at Fetakgomo Municipality, Limpopo Province

Phakoago, Manche Harry January 2007 (has links)
Thesis (MPA) --University of Limpopo, 2007 / HIV and AIDS pandemic poses a threat to both poor and rich communities alike. Communities face a developmental challenge as HIV and AIDS kills the lives of people who should improve their socio-economic position. It destroys both the Constitutional rights to life and human dignity. This is seen when people get sick and lose their potential to contribute to the development of their communities. The Fetakgomo communities, in the Limpopo Province, face the same challenge of fighting the pandemic for their social and economic development without sufficient resources. This study focuses on the socio-economic impact of HIV and AIDS on community development in Fetakgomo Municipality, Limpopo Province. Fetakgomo communities are situated about ± 90 km, South of Burgersfort. These communities are mostly poor and rural. The researcher used non-probability purposive sampling for this study. Three communities were selected and their leaders were chosen to participate in the study. Through qualitative research, the qualitative data were obtained through person to-person interviews and focus group interviews. The results of the study indicate that the social lives of community members are disrupted through death from the pandemic. In the two communities – Ga-Nchabeleng and Mohlaletse – there are orphans who are created by the pandemic. There is also a problem of lack of social cohesion created by prejudice around the disease, which raises a challenge in fighting the pandemic in the three villages. The issue of confidentiality compounds the situation in fighting the pandemic among members of the three communities as people are not open to talk freely about the impact of the pandemic on their lives. Economically, the pandemic is impacting on a few families that lose their incomes and are unable to buy electric services. The final results indicate that the impact of the pandemic is arguably very low. The communities are shown not to be doing enough to fight the impact of the pandemic. Even if the three communities are economically poor, the pandemic does not have serious impact on their material possessions. There is no real economic impact as members of the three communities are poor and at the same time a few families are affected in terms of losing their incomes. The impact of the pandemic is only experienced on the social lives where it breeds prejudice and secrecy among the people.
