The roles of teachers in enhancing effective classroom management strategies in Gauteng high schools, South Africa

Purpose: This study explores the challenges teachers face in their classroom management roles which are essential for fostering a supportive learning environment. It investigates teachers' roles in implementing management strategies and the obstacles hindering their effectiveness in high schools.
 Design/Methodology/Approach: The present study used semi-structured interviews to collect data from twelve Grade 10 teachers in three selected secondary schools located in the Ekurhuleni North District of Gauteng Province, South Africa. The data were interpreted using a phenomenological research design and interpretive paradigm. The study was based on ecological systems theory. Thematic analysis was used to make sense of the data.
 Findings: The study revealed that key roles of teachers in effective classroom management include appropriate classroom language, acting as managers and self-criticism and evaluation of performance. However, challenges such as insufficient teaching and learning resources and the low academic ability of learners impede the fulfilment of these roles.
 Conclusion: The study finds that continuous self-criticism and evaluation are critical for improving teaching and learning processes, although teachers play a critical role in monitoring classrooms and resolving difficulties imposed by low academic competence.
 Recommendations: Recommendations include comprehensive training and support for teachers, the implementation of diverse teaching strategies and a holistic consideration of the ecological system encompassing both learners and teachers.

45 Evaluation of Drug-Resistant Tuberculosis Guidelines and Outcomes by Treatment Site in South Africa

OBJECTIVES/GOALS: DR-TB care in South Africa includes decentralized treatment with shorter, all-oral regimens. Treatment guidelines direct regular clinical and laboratory evaluation to assess patient improvement. We therefore measured sputum collection frequency and follow-up time to assess fidelity to these guidelines in Gauteng Province, South Africa. METHODS/STUDY POPULATION: We included Rifampicin-resistant (RR) sputum specimens from the South African National Health Laboratory Service, which provides pathology services to 80% of the population, submitted between August 2022-September 2023. Patient data were obtained from a DR-TB registry and additional sputum specimen data were collected from follow-up laboratory worksheets. Follow-up spanned from first sputum collection date (baseline) to patient outcome date (e.g., completion, lost) or study closure date (if still on treatment). Monthly sputum submission rate was measured for those with ≥1 additional sputum submitted. We compared patient data by treatment site: at the specialized hospital vs. any other site, using Wilcoxon ranksum and χ2 tests. RESULTS/ANTICIPATED RESULTS: Baseline RR-TB specimens were available for 142 patients, of whom 28 (20%) had specimens submitted from the specialized hospital. Patients at the specialized hospital were older (median age 41 vs. 35.5 years, p=0.03), had higher baseline fluoroquinolone resistance (10% vs. 1%, p=0.01), and longer follow-up (median 5.2 vs. 3.5 months, p=0.01) compared to patients elsewhere. Further, 43 (30%) patients had ≥1 additional sputum submitted during follow-up. Among these, monthly sputum collection rates did not differ by site (0.3 vs. 0.3 sputum per month, p=0.89). We anticipate that increased sputum frequency will be associated with successful TB treatment outcomes based on preliminary findings. DISCUSSION/SIGNIFICANCE: These findings highlight ongoing challenges with routine laboratory follow-up according to DR-TB guidelines across treatment sites in South Africa. Future research is needed to determine reasons for low sputum collection rates, such as low patient adherence, variation in practice of healthcare workers, loss to follow-up, and clinical challenges.

Mental health services in Gauteng, South Africa: A proxy evaluation using pharmaceutical data.

South African legislation advocates for equitable access to mental healthcare services integrated into general healthcare settings. Mental, neurological, and substance use (MNS) disorders are often comorbid. Pharmacoepidemiology provides indirect evidence of service provision for conditions amenable to medicine treatment. The study aims to evaluate medicine procurement for MNS disorders at different service levels in the health system. The Public health sector, Gauteng province formed the setting for the study. A secondary analysis of the Gauteng pharmaceutical database was conducted using Anatomic Therapeutic Chemical (ATC) and defined daily dose (DDD) methodology. Anatomic Therapeutic Chemical classes of medicines for MNS disorders were included. Defined daily doses and costs were calculated per 1000 population served by each facility and service level. Statistical comparisons were made using chi-square testing. General healthcare settings accounted for 90% (R118 638 248) and specialised hospitals for 10% (R13 685 032) of expenditure on medicines for MNS disorders, procuring 94% (n = 49 442 474) and 6% (n = 3 311 528) of DDDs, respectively. Although district clinics procured 60% of DDDs, they procured the least per 1000 population served, whereas district hospitals procured the most. For almost all ATC classes, procurement differed significantly between municipalities at every service level and between specialised hospitals. In Gauteng province, most medicines for MNS disorders are procured by general healthcare services, but access to care may not be equitable. While population coverage at district clinics appears low, district hospitals may experience the greatest care burden. Research regarding quality of care at each service level is recommended. This study provides insight into service provision for MNS disorders.

Burnt out: A retrospective review of paediatric burns admissions at Chris Hani Baragwanath Academic Hospital 2015–2020

BackgroundBurn injuries in children in low- and middle-income countries are common, serious, and preventable. Despite the high burden of disease, there is a paucity of data on the profile of paediatric burns in South Africa. Such data are essential to local burn prevention strategies. MethodsA retrospective review of all recorded paediatric burns admissions to the paediatric burns unit at Chris Hani Baragwanath Academic Hospital was performed from 1 January 2015 – 31 December 2020. Ethical approval was obtained. Data extracted anonymously included patient age, sex, mechanism of injury, injury severity, date of injury and residential location. ResultsA total of 2980 admissions occurred during the study period. Infants ≤ 1 year accounted for 42.2 % (1259/2980), males 61.4 % (1689/2751), hot water burns 79.1 % (2357/2980), and major injury 40.1 % (1201/2980) of admissions. Most burn injuries occurred in winter (28.2 %, 842/2980), and most admitted patients lived in Soweto 45.5 % (1355/2980). ConclusionsMost burns admissions in the study period were characterised by male children less than one year of age, hot water burns, major burn injuries and admissions in the winter months. These results are similar to national and international data regarding age, sex, mechanism of injury and seasonality of paediatric burns. The results from the study have been utilised to inform Surgeons For Little Lives’ paediatric burns prevention campaigns in Soweto and Gauteng Province.

When bullying victims are also perpetrators: A qualitative study in high schools in Tshwane District, Gauteng Province

When bullying victims are also perpetrators: A qualitative study in high schools in Tshwane District, Gauteng Province

Experiences of families living with Nyaope users in Tshwane, Gauteng province.

Nyaope is one of the commonly used drugs in many low socio-economic communities in South Africa. Because of its highly addictive properties, the vast majority of users are not able to quit, which results in long-term difficulties for their families. The aim of this study was to explore and describe the experiences of families living with nyaope users in a township in Tshwane Metropolitan Municipality. Data were collected at the Social Development Centre, which serves a variety of social needs of families, including the various needs of families whose problems emanate from nyaope use. The family members were recruited from the registry of the centre. A qualitative design and in-depth interviews were used to collect data from a sample of family members who were purposively sampled. NVIvo 12 was used for thematic analysis of the data. Three major themes emerged from the data, these being, consequences of nyaope use on the family, family interventions, and coping strategies. Although the families have devised interventions and developed coping strategies, nyaope use remains a serious mental health challenge in affected families. The study highlighted the negative impact of nyaope on the social and mental health of the families. The assistance offered at Social Development is broad and general for substance abuse, but does little to mitigate the complex difficulties brought about by nyaope use.

Proximity to public green spaces and depressive symptoms among South African residents: a population-based study

BackgroundExposure to green spaces has been suggested to improve mental health and may reduce the risk of depression. However, there is generally limited evidence on the association between green spaces and depression originating from low-and middle-income countries and Africa in particular. Here, we investigate the association between proximity to public green spaces and depressive symptoms among residents of Gauteng Province, South Africa.MethodsWe used data from the 2017/2018 Gauteng quality of life survey. We included all individuals aged 18 years or older residing in the nine municipalities of Gauteng Province that completed the survey (n = 24,341). Depressive symptoms were assessed using the Patient Health Questionnaire-2. Proximity to public green spaces was defined as self-reported walking time (either less or greater than 15 min) from individuals’ homes to the nearest public green space. To assess the association between access to public green spaces and depressive symptoms, we used mixed-effects models, adjusted for age, sex, population group (African, Indian/Asian, Coloured (mixed race), and White), educational attainment, and municipality. We additionally performed stratified analyses by age, sex, educational attainment, and population group to evaluate whether associations differed within subgroups. Associations are expressed as prevalence ratios (PR) and their 95% confidence intervals (95% CI).ResultsWe observed a 6% (PR = 0.94, 95%CI = 0.92–0.96) prevalence reduction in depressive symptoms for individuals who reported that the nearest public green space was less than 15 min from their homes as compared to those who reported > 15 min. After stratification, this inverse association was stronger among females, individuals aged 35–59 years,those with higher levels of educational attainment, and Coloured individuals as compared to their counterparts.ConclusionOur findings suggest that public green spaces close to residential homes may be associated with a reduction in the occurrence of depressive symptoms among urban populations in resource-constrained settings like South Africa.

"All I know is that a disabled person is someone who is crippled": Using narratives of parents to unmask the misconceptions of Mild intellectual disabilities concept as a learning support hindrance.

Background: Learning-support provision by parents is key to children's scholastic success. However, when children are diagnosed with mild intellectual disabilities and in need of additional support, learning support provision is hindered. Aim: The study sought to investigate parents' experiences when providing learning support to children diagnosed with Mild intellectual disabilities. Setting: Using a phenomenological design and an interpretive paradigm, anchored in a qualitative research approach, data were gathered from parents whose children were diagnosed with Mild intellectual disabilities across three inclusive schools from disadvantaged backgrounds in the Gauteng province, in South Africa. Methods: Twenty-three (23) parents were purposefully selected to participate in the study by sharing their lived experiences. Data was collected using semi-structured interviews and thematic content data analysis methods. Bronfenbrenner's bio-ecological systems theory underpinned the study. Results: The findings revealed that the parents' misconception of the mild intellectual disability concept is one of the learning support hindrances. Conclusion: Parental empowerment through psycho-education was highlighted as a need for policy and practice adaptation.

New fossil Bovidae (Mammalia: Artiodactyla) from Kromdraai Unit P, South Africa and their implication for biochronology and hominin palaeoecology

Kromdraai is a Plio-Pleistocene site located in the Cradle of Humankind (Gauteng Province, South Africa). It has produced diverse and abundant faunal assemblages and key hominin specimens like the holotype of Paranthropus robustus and early Homo. We provide the first taxonomic study of the Bovidae Family from the hominin-bearing Unit P at Kromdraai and discuss its potential to unravel its paleoecological context. We describe the presence of an unknown medium-sized buffalo (Syncerus sp.) that could be closely related to S. acoelotus. The bovid assemblage from Kromdraai Unit P combines older Plio-Pleistocene (Gazella gracilior, Makapania broomi, Numidocapra cf. porrocornutus) and younger Pleistocene taxa (Tragelaphus strepsiceros, Oreotragus oreotragus, Raphicerus campestris, Damaliscus lunatus). Overall, these bovid species indicate a grassland-dominated environment for Unit P. Comparisons with other Plio-Pleistocene South African sites indicate that Australopithecus was associated with woodland and closed-wet environment-adapted taxa, whereas Homo was found in association with bovid species adapted to open and dry environments. In contrast, the assemblages associated with Paranthropus show an extensive range of environmental adaptation among the bovids. The biochronology indicates that Kromdraai Unit P accumulated between 2.9 and 1.8 Ma. If Kromdraai Unit P were to be confirmed to date to the older end of this scale, it would provide the earliest appearance of Paranthropus robustus, Numidocapra, and Damaliscus in southern Africa.

Traditional health practitioners' understanding of spirit possession in Gauteng province, South Africa.

Traditional health practitioners (THPs) understand spirit possession as a cultural or religious spirit occupying a person, while the mental healthcare providers understand it as a mental illness. The different understanding is based on manifestations that mimic that of mental illness, such as seeing and hearing things that others cannot see or hear. Spirit possession holds different meanings in different cultures and religions that could be either beneficial or detrimental. Furthermore, spirit possession is understood as a channel of communication between the living and the dead or God or a supernatural phenomenon in which a spirit owns a person. This study explored and interpreted THPs' understanding of spirit possession in Gauteng province, South Africa. Hermeneutic phenomenology study explored and interpreted the THPs' understanding of spirit possession in Gauteng province. In-depth individual interviews were conducted with 12 THPs who were selected through snowball sampling techniques. Data analysis followed Heidegger's and Gadamer's philosophies and Van Manen's six steps of the analytic approach. The findings revealed that THPs understood spirit possession as spiritual illness, ancestral calling and demonic spirit or witchcraft. Traditional health practitioners' understanding of spirit possession could promote mental health and prevent mental illness by providing support to a spirit-possessed person and referral to mental healthcare services. This study contributed that not all manifestations presented by persons with spirit possession are actual and clear-cut mental illness, but could be unwritten cultural and/ or religious illnesses that needs cultural and religious services also.

The Wellbeing of Healthcare Workers during COVID-19 Era in Public Primary Health Facilities in Johannesburg, South Africa.

As the world grappled with the COVID-19 pandemic, healthcare workers (HCWs) continued to provide uninterrupted health care service delivery; therefore, this disproportionately affected their wellbeing. Our study explored the wellbeing of HCWs during the COVID-19 era in public health facilities in the City of Johannesburg, Gauteng province, South Africa. A qualitative study was conducted among twenty (20) HCWs through face-to-face in-depth interviews (IDIs) in the form of semi-structured interviews, audiotapes, and transcribed verbatim, and thematically analyzed with NVivo version 10. The findings showed that over half of HCWs (aged between 27 and 60 years) tested positive for COVID-19. Also, one third of HCWs' family members tested positive while some died due to COVID-19 infection. Informed by the workers' wellbeing framework, four themes emerged with fourteen sub-themes. Firstly, unsafe work environment was characterized by human resource related challenges such as increased workload; staff shortage; insufficient resources, e.g., personal protective equipment (PPE); poor policies in terms of compensation/allowance for being infected with COVID-19; poor health services; and death of colleagues. Secondly, poor health outcomes were described as strained emotional (psychosocial distress) and physical (respiratory related conditions) wellbeing. Thirdly, home and community environments were negatively impacted by interrupted relationships with family and friends, and experiences of deaths of loved ones. Finally, HCWs engaged personal wellbeing strategies through self-motivation; staying positive; family support; and participating in resilience-promoting extra mural activities to cope during the pandemic. In conclusion, the wellbeing of HCWs was aggravated during the COVID-19 era and led to low morale and compromised healthcare quality. This study advocates for promotion of greater resilience, and psychological and physical safety of HCWs through evidence-based, multilevel-multicomponent interventions at the workplace, home, and community environments in addition to strengthening public health policies and response to future pandemics.

Mobilisation towards formal employment in the healthcare system: A qualitative study of community health workers in South Africa.

In low and middle-income countries, community health workers (CHWs) play a critical role in delivering primary healthcare (PHC) services. However, they often receive low stipends, function without resources and have little bargaining power with which to demand better working conditions. Using a qualitative case study methodology, we studied CHWs' conditions of employment, their struggle for recognition as health workers, and their activities to establish labour representation in South Africa. Seven CHW teams located in semi-urban and rural areas of Gauteng and Mpumalanga Provinces were studied. We conducted 43 in-depth interviews, 10 focus groups and 6 observations to gather data from CHWs and their representatives, supervisors and PHC facility staff. The data was analysed using thematic analysis method. In the rural and semi-urban sites, the CHWs were poorly resourced and received meagre remuneration, their employment outsourced, without employment benefits and protection. As a result of these challenges, the CHWs in the semi-urban sites established a task team to represent them. They held meetings and caused disruptions in the health facilities. After numerous unsuccessful attempts to negotiate for improved conditions of employment, the CHWs joined a labour union in order to participate in the local Bargaining Council. Though they were not successful in getting the government to provide permanent employment, the union negotiated an increase in their stipend. After the study ended, during the height of COVID-19 in 2020, when the need for motivated and effective CHWs became more apparent to decision makers, the semi-urban-based teams received permanent employment with a better remuneration. The task team and their protests raised awareness of the plight of the CHWs, and joining a formal union enabled them to negotiate a modest salary increase. However, it was the emergency created by the world-wide COVID-19 pandemic that forced decision-makers to acknowledge their reliance on this community-based cadre.

Genome Sequencing of Historical Encephalomyocarditis Viruses from South Africa Links the Historical 1993/4 Savanna Elephant (Loxodonta africana) Outbreak to Cryptic Mastomys Rodents.

From 1993 to 1994, 64 free-ranging elephants (Loxodonta africana) succumbed to encephalomyocarditis in the Kruger National Park, South Africa, of which 83% were adult bulls. Mastomys rodents were implicated as the reservoir host of the Encephalomyocarditis virus (EMCV) based on serology and RT-PCR. However, in the absence of sequence-confirmation of both the virus and the rodent host, definitive links between the elephant outbreak strains and rodent reservoir could not be established. In this study, we generate the first reference genome sequences for three historical EMCVs isolated from two Mastomys rodents and one Mastomys-associated mite, Laelaps muricola, in Gauteng Province, South Africa, in 1961. In addition, near-complete genome sequences were generated for two elephant outbreak virus strains, for which data were previously limited to the P1 and 3D genome regions. The consensus sequence of each virus was determined using a PCR-Sanger sequencing approach. Phylogenetic analysis confirmed the three near-identical (99.95-99.97%) Mastomys-associated viruses to be sister to the two near-identical (99.85%) elephant outbreak strains, differing from each other at 6.4% of sites across the ~7400-nucleotide region characterised. This study demonstrates a link between Mastomys-associated viruses and the historical elephant outbreak strains and implicates Mastomys as reservoirs of EMCV in South Africa.

Absence of Tuberculosis-Causing Mycobacteria from Slaughtered Livestock Tissues and Environmental Samples, Gauteng Province, South Africa.

Mycobacterium tuberculosis complex (MTBC) is a group of bacteria responsible for causing tuberculosis in animals and humans. In South Africa (S.A), slaughterhouses are registered by the government and closely inspected and audited for hygienic slaughter practices. Meat inspection to detect lesions has been used for passive surveillance, monitoring, and diagnosis of the disease status. Information on the current status of bovine tuberculosis (bTB) in livestock in the country is limited. Hence, we investigated the occurrence of Mycobacterium spp. in the tissues of slaughtered livestock and environmental samples in abattoirs in Gauteng province of South Africa (S.A). The cross-sectional study employing random sampling from cattle, pigs, and sheep (with the collection of liver, lung, spleen, and different lymph nodes) irrespective of lesions was carried out in 19 red meat abattoirs. Five hundred animals were sampled, comprising cattle (n = 369), pigs (n = 90), and sheep (n = 41). Additionally, 19 environmental samples were collected from feedlots, or where animals drink water while awaiting slaughter, to identify mycobacterial species using culture, acid-fast bacteria staining, and polymerase chain reaction (PCR). The Chi-square and Fisher's Exact tests were used to detect statistically significant differences in the frequency of detection of Mycobacterium spp. according to the variables investigated (types of tissues, livestock, abattoirs, etc.). The PCR assays detected no MTBC complex species DNA in the bacterial isolates from cattle (n = 32). Sequence analysis (16S rDNA) of the isolates from eight cattle confirmed only two species, namely Mycobacterium colombiense (99.81% identity) and Mycobacterium simiae (99.42% identity). The remaining isolates were identified as members of the Actinomadura species. From the environmental samples, bacterial isolation was made from three samples, and two could only be identified up to the genus level (Mycobacterium species) while the remaining isolate was identified as Mycobacterium senuense (99.22% identity). The study revealed the absence of bovine tuberculosis-causing pathogens in red meat abattoirs of the Gauteng province. Although non-tuberculous Mycobacteria have been implicated as potentially causing tuberculosis-like diseases in livestock, their occurrence in the current study was found to be low, but the potential to cause disease cannot be ignored.

Reaching consensus on factors impacting optimal use of an orthopaedic emergency theatre in a public hospital.

The operating theatre (OT) complex of hospitals represents areas of considerable expenditure with regard to costs and requires maximum use to ensure optimum cost benefit for both patients and the hospital. Inefficient use of an operating theatre room (OTR) may result in hospital wasteful expenditure and frustrations for patients owing to surgery delays, cancellations and prolonged hospitalisation while waiting. The aim of the study was to explore and describe using a consensus method, factors impacting the use of an emergency orthopaedic theatre that can be optimised in a selected public hospital in Gauteng province. The study was conducted by a professional nurse and orthopaedic surgeon working in the theatre of a selected public hospital in Gauteng province. A qualitative, explorative and descriptive design was adopted. Data were collected using a nominal group technique (NGT) among professional nurses and orthopaedic surgeons. Data analysis was done through cross-analysis where participants reached a consensus on the voted ideas from the group. Consensus was reached and three main themes emerged: (1) inadequate resources; (2) poor organisation and (3) communication. The optimal use of an emergency orthopaedic theatre is influenced by the availability of resources being human and material, good organisation and clear communication. The study has demonstrated that a variety of factors needs to be considered to optimise the use of an orthopaedic emergency theatre. The management of an OT requires a concerted effort from the nurses and doctors.

Prevalence and association of HIV and tuberculosis status in older adults in South Africa: an urgent need to escalate the scientific and political attention to aging and health.

This study examined the prevalence and sociodemographic factors among older adults with HIV and TB status in South Africa. This data was cross-sectional and obtained from the 2019 General Household Surveys in South Africa. Adults 50 years and over with reported HIV and TB status were included (N = 9,180,047). We reported statistical analyses of the descriptive, Chi-square and Fisher's exact tests, and binary logistic regression. The study has found a prevalence rate of HIV to be 5.3% and TB to be 2.9% among older adults aged 50 years and above in South Africa. However, the study found HIV and TB to be highest among older adults residing in Gauteng, KwaZulu-Natal and Eastern Cape provinces. For HIV status, the female gender [AOR = 0.80*, CI 95% = 0.80-0.80] and secondary education [AOR = 0.57, CI 95% = 0.56-0.58] have lower odds of association among older adults with HIV. Regarding TB status, primary education [AOR = 1.08*, CI 95% = 1.06-1.10] and diabetes [AOR = 1.87*, CI 95% = 1.82-1.91] have lower likelihoods of associations among older adults with TB. There is an urgent need to escalate scientific and political attention to address the HIV/TB burden in older adults and, public health policymakers need to take cognizance of the interdependence of inequality, mobility, and behavioural modification among this high-risk population.

Detection of Pathogenic Serogroups and Virulence Genes in Listeria monocytogenes Strains Isolated from Beef and Beef Products Retailed in Gauteng Province, South Africa, Using Phenotypic and Polymerase Chain Reaction (PCR)-Based Methods.

South Africa recently (2017-18) experienced the largest outbreak of human listeriosis in the world caused by L. monocytogenes following the consumption of "polony," a ready-to-eat meat product. Most (59%) cases originated from Gauteng province, South Africa. As a follow-up study to the outbreak, we used standard bacteriological and molecular methods to determine the prevalence of pathogenic and virulent serogroups of L. monocytogenes in various beef and beef products retailed in Gauteng province, South Africa. The overall prevalence of Listeria spp. was 28% (112/400), comprising Listeria monocytogenes (9.3%), Listeria innocua (16.3%), and Listeria welshimeri (2.5%) (p < 0.001). It is crucial to have detected that the region (p=0.036), type of product (p=0.032), and temperature at storage (p=0.011) significantly affected the occurrence of L. monocytogenes in beef products. It is alarming that pathogenic serogroups 4b-4d-4e (51.4%) and 1/2a-3a (43.2%) were detected among the isolates of L. monocytogenes. Importantly, they were all carriers of seven virulence-associated genes (hlyA, inlB, plcA, iap, inlA, inlC, and inlJ). Our study also demonstrated that 16.7% of "polony" samples investigated were contaminated with L. monocytogenes. Considering that pathogenic and virulent L. monocytogenes contaminated beef and beef products retailed in South Africa, the food safety risk posed to consumers remains and cannot be ignored. Therefore, it is imperative to reduce the contamination of these products with L. monocytogenes during beef production, processing, and retailing to avoid future outbreaks of human listeriosis in the country.

Radon exposure risks among residents proximal to gold mine tailings in Gauteng Province, South Africa: a cross-sectional preliminary study protocol.

Gold mine tailings, a legacy of the mining industry, harbors significant amount of radon gas, a classified human carcinogen. Radon exposure, especially near tailings, is a significant public health threat, potentially leading to increased risk of lung cancer, leukemia, and chronic obstructive pulmonary disease (COPD). These health problems are often associated with lower survival rates and significant financial burdens. This ongoing research aim to evaluating the relationship between indoor radon exposure and lung cancer, leukemia, and COPD risks among residents proximal to gold mine tailings in Gauteng Province, South Africa. This cross-sectional preliminary study focus on two distinct groups: Riverlea (exposed group, <2 km to Gold mine tailings) and Orlando East (unexposed group, >2 km to Gold mine tailings). Indoor radon levels is measured using AlphaE monitors, while health risks (lung cancer, leukemia, and COPD) linked to exposure are evaluated through interview-administered questionnaire and secondary data from Gauteng Health Department. Of the 476 residents randomly selected for this study, 300 have already participated, with balanced representation from both the exposed and unexposed groups. The study will compare indoor radon levels and health outcomes between the two groups. This study's results could aid in creating targeted interventions and policies to mitigate indoor radon exposure risks and safeguard vulnerable communities from this significant public health hazard.
