Understanding the differential impacts of COVID-19 among hospitalised patients in South Africa for equitable response.

BACKGROUND: There are limited in-depth analyses of COVID-19 differential impacts, especially in resource-limited settings such as South Africa (SA). OBJECTIVES: To explore context-specific sociodemographic heterogeneities in order to understand the differential impacts of COVID-19. METHODS: Descriptive epidemiological COVID-19 hospitalisation and mortality data were drawn from daily hospital surveillance data, National Institute for Communicable Diseases (NICD) update reports (6 March 2020 - 24 January 2021) and the Eastern Cape Daily Epidemiological Report (as of 24 March 2021). We examined hospitalisations and mortality by sociodemographics (age using 10-year age bands, sex and race) using absolute numbers, proportions and ratios. The data are presented using tables received from the NICD, and charts were created to show trends and patterns. Mortality rates (per 100 000 population) were calculated using population estimates as a denominator for standardisation. Associations were determined through relative risks (RRs), 95% confidence intervals (CIs) and p-values <0.001. RESULTS: Black African females had a significantly higher rate of hospitalisation (8.7% (95% CI 8.5 - 8.9)) compared with coloureds, Indians and whites (6.7% (95% CI 6.0 - 7.4), 6.3% (95% CI 5.5 - 7.2) and 4% (95% CI 3.5 - 4.5), respectively). Similarly, black African females had the highest hospitalisation rates at a younger age category of 30 - 39 years (16.1%) compared with other race groups. Whites were hospitalised at older ages than other races, with a median age of 63 years. Black Africans were hospitalised at younger ages than other race groups, with a median age of 52 years. Whites were significantly more likely to die at older ages compared with black Africans (RR 1.07; 95% CI 1.06 - 1.08) or coloureds (RR 1.44; 95% CI 1.33 - 1.54); a similar pattern was found between Indians and whites (RR 1.59; 95% CI 1.47 - 1.73). Women died at older ages than men, although they were admitted to hospital at younger ages. Among black Africans and coloureds, females (50.9 deaths per 100 000 and 37 per 100 000, respectively) had a higher COVID-19 death rate than males (41.2 per 100 000 and 41.5 per 100 000, respectively). However, among Indians and whites, males had higher rates of deaths than females. The ratio of deaths to hospitalisations by race and gender increased with increasing age. In each age group, this ratio was highest among black Africans and lowest among whites. CONCLUSIONS: The study revealed the heterogeneous nature of COVID-19 impacts in SA. Existing socioeconomic inequalities appear to shape COVID-19 impacts, with a disproportionate effect on black Africans and marginalised and low socioeconomic groups. These differential impacts call for considered attention to mitigating the health disparities among black Africans.

HIV risk exposure among South African children in public health facilities.

The study investigates the risk exposure to HIV infection among South African children aged 2-9 years served by public health services. Together with their biological mothers, 3471 children and were recruited from inpatient and outpatient children in the Free State Province. Blood samples were taken by professional nurses and a history taken of exposure factors associated with HIV transmission. DNA testing was used to confirm biological maternity where the child was HIV-positive and the mother HIV-negative. Mother-child pairs were stratified by mother's HIV status. Exposure factors related to the child's HIV status were examined in each stratum using a chi-square test. Independent factors were then included in a multiple logistic regression model. Having an HIV-positive mother was strongly related to HIV infection in children (OR: 310; 95%CI: 148-781). However, seven HIV-positive children had HIV-negative mothers. Transmission in this group was significantly associated with breastfeeding by a non-biological mother (OR: 437; 95%CI: 53-5020), being fed with expressed breast milk from a milk room (OR: 37.6; 95%CI: 6.2-259.0), dental injection history (OR: 31.5; 95%CI: 4.5-189.4) and visits to a dentist (OR: 26.9; 95%CI: 4.4-283.5). Although mother-to-child-transmission is shown to be the primary mode of HIV transmission in South African children, the few HIV-positive children infected by other modes of transmission suggest a potential risk of non-vertical HIV infections. These infections can be prevented through education and improved infection-control procedures.

Infection control practices in public dental care services: findings from one South African Province.

Infection control practices which increase the risk of blood-borne virus transmission with associated dental practice in one South African province were studied. All 24 state dental clinics were observed for adequate provision to carry out good infection prevention and control (IPC) practice, 75 staff including dentists, nurses and dental assistants were interviewed to assess IPC knowledge and 23 dental procedures were observed. Significant findings were the difference between knowledge and practice, despite adequate provisions for safe infection control practice. The lack of protective eye wear during a dental procedure, not washing hands between patients, not disassembling an item prior to disinfection or sterilization, and not using a sterile drill for each patient were identified. A rapid method for detection of occult blood was used as a marker for inadequate IPC practice. Contaminated dental items of equipment just prior to patient use in 25% of equipment tested and 37% of surfaces and surrounding areas in the dental clinics and units were recorded. This study concludes that, despite provision for safe dental practice available in state dental clinics, there was a lack of knowledge application in clinical practice. The risk of blood-borne virus transmission in a population with high human immunodeficiency virus (HIV) prevalence cannot be ignored.

Contraception coverage and methods used among women in South Africa: A national household survey.

BACKGROUND: Globally, family planning services are being strengthened and the range of contraceptive choices expanded. Data on contraceptive coverage and service gaps could help to shape these initiatives. OBJECTIVE: To assess contraception coverage in South Africa (SA) and identify underserved populations and aspects of programming that require strengthening. METHODS: Data from a 2012 SA household survey assessed contraception coverage among 6 296 women aged 15 - 49 years and identified underserved populations. RESULTS: Two-thirds had an unintended pregnancy in the past 5 years, a quarter of which were contraceptive failures. Most knew of injectable (92.0%) and oral contraception (89.9%), but fewer of intrauterine devices (56.1%) and emergency contraception (47.3%). Contraceptive prevalence was 49.1%, and 41.8% women used modern non-barrier methods. About half had ever used injectable contraception. Contraception was lower in black Africans and younger women, who used a limited range of methods. CONCLUSION: Contraception coverage is higher than many previous estimates. Rates of unintended pregnancy, contraceptive failure and knowledge gaps, however, demonstrate high levels of unmet need, especially among black Africans and young women.

Utilization of delivery services in the context of prevention of HIV from mother-to-child (PMTCT) in a rural community, South Africa.

The aim of this study was to investigate the utilization of delivery services in the context of PMTCT in a rural community in South Africa. Based on a cross-sectional survey, the sample included 870 pregnant women who had delivered before recruited from five PMTCT clinics and surrounding communities. Results indicated that 55.9% had delivered their last child in a health care facility and 44.1% at home (mostly without assistance from a traditional birth attendant). The odds of access to the health facility were (1) women who stayed close to the hospital (OR = 2.87), (2) those who had higher formal education (OR = 1.55), (3) higher traveling costs (affordability) to get to nearest clinic (OR = 1.77), and (4) those who were single (OR = 1.58). Childbirth experiences of the mother or mother-in-law greatly influenced the delivery choices in terms of home delivery. The majority of the pregnant women were aware of mother-to-child HIV transmission but only 9% of the pregnant women had ever been tested for HIV. HIV knowledge, HIV testing behaviour and attitudes were found to be not associated with the delivery option.

Relationship of chronic stress, social support, and coping style to health among Namibian refugees.

This study investigates how social support and coping style affect the relationship between a traumatic chronic stressor and health status. A population of 88 Namibian refugees living in an equatorial region of Africa participated in the study. The central hypothesis was that social support and coping style moderate the relationship between length of stay in exile (a proxy measure of chronic stress) and health status (symptoms of generalized anxiety disorders, self-reported physical health status and length of stay in hospital). The results show that when social support is high the relationship between length of stay in exile and all three health outcomes is substantially reduced. When social support is low, the relation between stress and poor health outcomes is high. Coping style moderates the relationship between length of stay in exile and period of hospitalization but has no effect on level of anxiety or perceived health status. When both social support and coping style are simultaneously considered, the best results emerge.

Depressive symptomatology among Namibian adolescent refugees.

Symptoms of depression have been considered rare in sub-Saharan populations. Using a standard assessment measure of depressive symptomatology, the Beck Depression Inventory, the prevalence of symptoms of depression was obtained from a group (N = 56) of Namibian refugees residing in a sub-Saharan host country. Contrary to expectations, the rates of self-reported symptoms were quite frequent, with many symptoms reported as moderate or severe by a large proportion of these youths. Using a stress model to explore these data, it was demonstrated that social support ameliorated the effects of chronic stress, as represented by the length of time in exile. It is argued that adaptation, acculturation, and adolescent developmental demands result in self-reports of depressive symptoms. These demands, however, are lessened in intensity by a strong social support system that is especially helpful early in the exile period.

Leading causes of infant deaths in the District of Columbia.

Causes of infant deaths were analyzed from the linked vital records of 1988 for the District of Columbia. According to a new cause-of-death classification, 57% of the deaths were attributed to "prematurity and related conditions," as compared with only 31% due to "disorders relating to short gestation and unspecified low birthweight" and respiratory distress syndrome (RDS) in the three-digit ICD-9 classification. Two thirds of infant deaths were "preventable." However, 92% of these occurred to infants weighing less than 1500 g. Not only was a greater proportion of black deaths (71%) preventable as compared to nonblacks (40%), but also 15% of the preventable deaths among blacks were due to causes unrelated to prematurity. The Infant Mortality Rate (IMR) in the District of Columbia would be reduced from 23.2 to 7.7 if all preventable deaths were prevented, to 20.9 if only the preventable deaths not related to prematurity were prevented, and to 15.2 if the percentage of "preventable" deaths among blacks was brought down to the level of nonblacks. Mortality from RDS was substantially higher in the District of Columbia compared with blacks nationally and appeared to offer the best opportunity for reduction. However, detailed examination of circumstances surrounding each infant death would be necessary to inform the strategies for the reduction in IMR.

Social determinants for HIV prevalence among South African educators.

HIV prevalence among women in South Africa continues to be high despite the availability of a comprehensive plan for the control of HIV/AIDS and a plethora of prevention programmes. Any explanation for the ongoing high HIV prevalence continues to be elusive. The objective of this study was to understand the relationship between HIV, gender, race and socioeconomic status among South African public sector educators in order to inform prevention programmes. A cross-sectional survey involving a probability sample of 1,766 schools out of 26,713 in the Department of Education Register of School Needs was selected. A sample of 24,200 respondents out of 356,749 public sector educators participated in the study. Nurses registered with the South African Nursing Council were recruited, trained to conduct interviews and to collect specimens for HIV testing. The study found an association between HIV, gender, race and socioeconomic status among educators. African educators showed a higher HIV prevalence than other race groups. Among females, the highest HIV prevalence was among educators aged 25-35 years and in males aged 36-49 years. Further, educators with a high income and educational qualifications had a lower HIV prevalence compared to educators with low income and low educational qualifications, regardless of sex. Migration and marital factors were also found to play a role in HIV infection. The results suggest that HIV prevention needs to take into account critical issues around empowerment of vulnerable groups such as women and certain race groups to be able to implement safe sexual practices and therefore reduce HIV infections.

Translating research into policy: the case of orphans and vulnerable children in South Africa.

Policies are often developed without taking into account social science research findings and recommendations, despite the plethora of such research studies. This is largely because researchers and policy makers often work in isolation, yet if they worked synergistically they could have a significant impact on implementing interventions known to work to improve the lives of populations. Several approaches have been advanced to encourage policy makers to take heed of scientific findings and to urge scientists to take into account the needs of policy makers in designing their research agenda. This paper aims to illustrate how policy has been informed using the case study of the Orphans and Vulnerable Children project in South Africa. It further highlights the successes and challenges encountered thus far with this project. In some countries, particularly those of the north, there has been major progress in bridging this gap between research and policy; however, in developing countries much remains to be done.

New approaches, new activities and new outcomes in international conferences on HIV/AIDS in Africa--report of the 3rd African Conference on the Social Aspects of HIV/AIDS, Dakar, 10-14 October 2005.

Africa's HIV/AIDS situation remains cause for concern. The impact of HIV is considerable and threatens the survival and development of African societies. Although much has been attempted, the results still leave much to be desired. AIDS is an epidemic that needs to be addressed with much creativity and spirit of initiative. It is against this background that the 3rd African conference on the social aspects of HIV/AIDS brought innovations in the way international conferences are designed, activities implemented and results obtained. The innovations concerned the approach to international conferences and take into account reconceptualising HIV/AIDS so as to encourage holistic approaches and better visibility of vulnerable groups. The activities of the conference were organised in such a way as to get people living with HIV/AIDS (PLWHA), grassroots communities and marginalised groups to play a focal role. The conference offered an opportunity for developing cultural activities that would translate the African cultural concepts that had been identified as important in the HIV situation and response analysis. Interaction at the conference created an opportunity to analyse the various dimensions of the political, cultural and economic determinants. The conference offered food for thought around response construction while singling out the themes of urgency and acceleration of response, synergy construction, and coordination and conception of political responses.

Training opportunities for public health in South Africa.

PIP: South Africa has 4 public health training institutions: the Transvaal School of Public Health, the Public Health Programme of the University of the Western Cape, the Natal Institute of Community Health Education, and the Eastern Cape School of Public Health. They are interinstitutional (universities, polytechnic schools, health service providers, statutory research councils, and nongovernmental organizations). A steering committee heads up each institution. One person leads the committee, managing all activities and making sure that all activities fulfill the requirements of the steering committee. The Epidemiological Society of Southern Africa also contributes to public health training through its annual forum for public health researchers and meetings of public health personnel, where they talk about public health training needs. Interest in public health training reemerged in the late 1980s, mainly due to the dismantling of apartheid, which called for a restructuring of the public health service. Primary health care is the focus of all South Africa's public health institutions. Courses convey community-oriented approaches in the design of health programs and research. They use a multidisciplinary approach to education. They examine socioeconomic conditions affecting health as well as the biomedical aspects of public health. The Transvaal School of Public Health targets post-basic and post-graduate health staff at the middle or senior level positions. On the other hand, the Eastern Cape School of Public Health targets field workers, primary health care workers, and public health professionals. Currently, the programs only provide a Master of Public Health. As South Africa makes its way to democracy and with adequate funding, public health training in South Africa will result in positive efforts helping all of Africa.^ieng

Behavioural responses of South African youth to the HIV/AIDS epidemic: a nationwide survey.

South Africa is reported to have the largest number of people living with HIV/AIDS in the world. The present study investigated the behavioural responses of South African youth to the HIV/AIDS epidemic. A multi-stage stratified cluster sample of 2,430 youths aged 15-24 was selected, 46.9% of them males and 53.1% females. Nurses administered questionnaires to consenting youths, measuring behavioural risks and also took an oral fluid specimen for HIV antibody testing. It was found that the median age of sexual debut for both sexes was 16.5 years; most of the youths were sexually experienced with no variation by sex; sexual experience was highest among Africans living in informal urban areas; partner turnover was low and multiple partners were more common among African males living in urban informal settings; sexual frequency among sexually active youth was relatively low; secondary abstinence during the past 12 months was 24%; condom use at last sexual intercourse was high, at 52.8% for males and 47.6% for females, especially among Africans living in urban informal settings; and the majority of youths (74%) indicated that they had discussed HIV prevention with their partners during the past 12 months. These results suggest that South African youth are heeding the message to abstain, be faithful and use a condom; messages that are at the core of South Africa's HIV/AIDS prevention programme.

HIV/AIDS prevalence among South African health workers.

INTRODUCTION: Studies on HIV prevalence among health workers usually focus on occupational exposure to HIV. Little is known about HIV prevalence in this group. However, it is expected that HIV prevalence among health workers will reflect prevalence in their society. OBJECTIVE: To determine HIV prevalence among South African health workers. METHOD: A stratified cluster sample was drawn of 5% of health facilities in South Africa (N = 222) representative of the public and private health sectors in South Africa. The sample was designed to obtain a nationwide representative sample of medical professionals and non-professional health workers. A subsample comprising health workers in four provinces was tested for HIV status. The Orasure HIV-1 device in combination with the Vironostika HIV UNI-Form II plus O enzyme-linked immunosorbent assay (ELISA) kits were used to collect oral fluid specimens for HIV testing. RESULTS: Based on a sample of 721 health workers and a response rate of 82.5% (or 595 respondents), the study found that an estimated 15.7% (95% confidence interval (CI): 12.2-19.9%) of health workers employed in the public and private health facilities located in four South African provinces, were living with HIV/AIDS in 2002. Among younger health workers, the risk is much higher. This group (aged 18-35 years) had an estimated HIV prevalence of 20% (95% CI: 14.1-27.6%). Non-professionals had an HIV prevalence of 20.3%, while professionals had a prevalence of 13.7%. CONCLUSION: HIV prevalence among health workers in South Africa is high; this calls for the introduction of antiretroviral programmes targeting them. In addition, there is a need for the development of new policy regarding placement of infected health workers in tuberculosis (TB) wards, coupled with vigorous human resource planning to replace the health workers likely to die from AIDS. Infection control procedures also need to be reviewed.

Marital status and risk of HIV infection in South Africa.

OBJECTIVE: Available evidence on the relationship between marital status and HIV is contradictory. The objective of this study was to determine HIV prevalence among married people and to identify potential risk factors for HIV infection related to marital status in South Africa. METHODS: A multistage probability sample involving 6 090 male and female respondents, aged 15 years or older was selected. The sample was representative of the South African population by age, race, province and type of living area, e.g. urban formal, urban informal, etc. Oral fluid specimens were collected to determine HIV status. A detailed questionnaire eliciting information on socio-demographic, sex behaviour and biomedical factors was administered through face-to-face interviews from May to September 2002. RESULTS: HIV prevalence among married people was 10.5% compared with 15.7% among unmarried people (p-value < 0.001). The risk of HIV infection did not differ significantly between married and unmarried people (odds ratio (OR) = 0.85, 95% confidence interval (CI): 0.71 - 1.02) when age, sex, socio-economic status, race, type of locality, and diagnosis of a sexually transmitted infection (STI) were included in the logistical regression model. However, the risk of HIV infection remained significantly high among unmarried compared with married people when only sex behaviour factors were controlled for in the model (OR 0.55; 95% CI: 0.47 - 0.66). CONCLUSIONS: The relationship between marital status and HIV is complex. The risk depends on various demographic factors and sex behaviour practices. Increased prevention strategies that take socio-cultural context into account are needed for married people.
