Abstract
INTRODUCTION Mozambique is a high-burden country for tuberculosis (TB). International studies show that TB is a disease that tends to cluster in specific regions, and different risk factors (HIV prevalence, migration, overcrowding, poverty, house condition, temperature, altitude, undernutrition, urbanization, and inadequate access to TB diagnosis and treatment) are reported in the literature to be associated with TB incidence. Although Mozambique has a higher burden of TB, the spatial distribution, and determinants of TB incidence at the sub-national level have not been studied yet for the whole country. Therefore, we aimed to analyze the spatial distribution and determinants of tuberculosis incidence across all 154 districts of Mozambique and identify the hotspot areas. METHOD We conducted an ecological study with the district as our unit of analysis, where we included all cases of tuberculosis diagnosed in Mozambique between 2016 and 2020. We obtained the data from the Mozambique Ministry of Health and other publicly available open sources. The predictor variables were selected based on the literature review and data availability at the district level in Mozambique. The parameters were estimated through Bayesian hierarchical Poisson regression models using Markov Chain Monte Carlo simulation. RESULTS A total of 512 877 people were diagnosed with tuberculosis in Mozambique during our five-year study period. We found high variability in the spatial distribution of tuberculosis incidence across the country. Sixty-two districts out of 154 were identified as hotspot areas. The districts with the highest incidence rate were concentrated in the south and the country's central regions. In contrast, those with lower incidence rates were mainly in the north. In the multivariate analysis, we found that TB incidence was positively associated with the prevalence of HIV (RR: 1.23; 95 % CrI 1.13 to 1.34) and negatively associated with the annual average temperature (RR: 0.83; 95 % CrI 0.74 to 0.94). CONCLUSION The incidence of tuberculosis is unevenly distributed across the country. Lower average temperature and high HIV prevalence seem to increase TB incidence. Targeting interventions in higher-risk areas and strengthening collaboration between HIV and TB programs is paramount to ending tuberculosis in Mozambique, as established by the WHO's End TB strategy and the Sustainable Development Goals.

Abstract
Introduction migrant mine workers are susceptible to engage in risky sexual behaviour due to their high mobility, putting at risk their families and home communities. Because comprehensive knowledge about HIV/AIDS is a key factor in reducing HIV infections, this study aims to understand the current state of knowledge about HIV in these communities, estimate HIV prevalence and evaluate the risk behaviour associated with comprehensive knowledge. Methods secondary data analysis of a cross-sectional survey conducted in two communities of origin of mine workers in Gaza Province, targeting current and former mine workers of the South African mines and their relatives. Households were selected using simple random sampling methodology. Chi-squared tests and logistic regression analysis were used to assess statistical differences between comprehensive knowledge and categorical variables. Results from a total of 1,012 participants, only 22.0% of the respondents had comprehensive knowledge about HIV. The overall HIV prevalence in these communities was 24.2% and the HIV prevalence in individuals with comprehensive knowledge was 18.6%. Among the respondents with comprehensive knowledge, 33.1% were male, 22.0% have worked in a South African mine and the median age was 34 years old. Individuals from Muzingane were almost twice as likely (AOR 1.7; 95% IC 1.21-7.44, p=0.014) to have less comprehensive knowledge about HIV than their counterparts in Patrice Lumumba. Conclusion the results demonstrate a low level of comprehensive knowledge about HIV amongst this population and reveal an association between comprehensive knowledge about HIV and prevalence. Therefore, it is important to improve knowledge about HIV, its transmission and prevention amongst this population.

Access of migrant gold miners to compensation for occupational lung disease: Quantifying a legacy of injustice. J Migr Health 2021; 4:100065. [PMID: 34729543 PMCID: PMC8546409 DOI: 10.1016/j.jmh.2021.100065] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 09/28/2021] [Accepted: 10/04/2021] [Indexed: 11/24/2022] Open
Abstract
Background A legacy of the South African gold mining industry, now in decline, is a large burden of silicosis and tuberculosis among former migrant miners from rural South Africa and surrounding countries, particularly Lesotho and Mozambique. This neglected population faces significant barriers in filing claims for compensation for occupational lung disease. The objective of the study was to gain insight into the extent of such barriers, particularly for former miners and cross-border migrants. Methods The database of a large gold mining company and the statutory compensation authority were analyzed for the period 1973–2018 by country of origin, age, and employment status at the time of claim filing. Proportions and odds ratios (ORs) for each of the compensable diseases were calculated by the above variables. Processing delays of claims were also calculated. Results Annual company employment declined from 240,718 in 1989 to 43,024 in 2018 and the proportion of cross-border migrants within the workforce from 51.0 to 28.1%. The compensation database contained 68,612 claims. The majority of compensable claims in all diagnostic categories were from active miners. The odds of cross-border miners relative to South African miners filing a claim depended on employment status. For example, the OR for Lesotho miners filing while in active employment was 1.86 (95% CI 1.81, 1.91), falling to 0.94 (95% CI 0.91, 0.98) among former miners. The equivalent findings for Mozambiquan miners were 0.95 (95% CI 0.91, 1.00), falling to 0.44 (95% CI 0.41, 0.47). Median processing delays over the whole period were from 1.1 years from filing to adjudication, and 3.8 years from filing to payment. Conclusions The findings provide a quantitative view of differential access to occupational lung disease compensation, including long processing delays, among groups of migrant miners from the South African gold mines. There is a deficit of compensable claims for silicosis and silico-tuberculosis among former miners irrespective of country of origin. While cross-border miner groups appear to file more claims while active, this is reversed once they leave employment. Current large-scale efforts to provide medical examinations and compensation justice to this migrant miner population need political and public support and scrutiny of progress.

HIV prevalence and TB in migrant miners communities of origin in Gaza Province, Mozambique: The need for increasing awareness and knowledge. PLoS One 2020; 15:e0231303. [PMID: 32267866 PMCID: PMC7141647 DOI: 10.1371/journal.pone.0231303] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Accepted: 03/20/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND As part of ongoing efforts to generate evidence needed on HIV and tuberculosis (TB) to inform policies and programs aimed to improve the health outcomes of migrants and communities affected by migration and mining, a preliminary investigation was conducted through a biological and behavioral (BBS) approach related to HIV and TB in two communities of origin of migrant mineworkers in Gaza Province. The main objective was to determine the prevalence of HIV and the rates of asymptomatic infection by TB, and the social and behavioral risk factors associated. METHODS A cross-sectional survey was conducted from May to June 2017 using a simple random sampling methodology. Eligible participants were individuals who were living in the community at the time the survey was conducted, which included adult mine workers and members of their families aged 18 and above. A socio-behavioral questionnaire was administered, blood specimens were collected for HIV testing (Determine/Unigold) and sputum for TB (GeneXpert MTB/RIF) was collected. The statistical analysis was performed using the R studio software to produce means, proportion and odds ratio at 95% confidence intervals. RESULTS A total of 1012 participants were enrolled, 75.2% were females, with a median age of 34. The overall prevalence of HIV found in the two communities was 24.2% (CI: 21.6-27.0) and was higher in the rural community (31.6%; 95% CI: 27.0-35.3). The prevalence of active TB was found to be 0.3% (n = 3) while 7.5% of the participants self-reported to have been previously diagnosed with TB at some point in their life. Only 2.8% of participants had knowledge of the basic principles of TB transmission. Condom use at last sexual intercourse with a regular partner was low among both sexes (17.3% male and 12.6% female). A considerable proportion of participants had not been aware of their HIV positive serostatus(31.1% female and 25.0% male). About 1/3 of the participants had had a history of STIs. CONCLUSION The results of this survey confirm a high prevalence of HIV in communities of origin of migrant miners in Gaza province. Findings also demonstrated low levels of awareness/ knowledge and prevention of TB and HIV. It is important to strengthen strategies that encourage regular HIV testing and TB screening. Appropriate communication interventions on methods of transmission and prevention of HIV and TB in these communities must be intensified, as well as ensuring ongoing linkage to TB and HIV social and healthcare services.

Khoza-Shangase K. Burden of disease: A scoping review of HIV/AIDS and TB in occupational noise-induced hearing loss. SOUTH AFRICAN JOURNAL OF COMMUNICATION DISORDERS 2020; 67:e1-e9. [PMID: 32129660 PMCID: PMC7136822 DOI: 10.4102/sajcd.v67i2.669] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Revised: 01/30/2020] [Accepted: 02/06/2020] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Occupational noise-induced hearing loss (ONIHL) does not occur in isolation from other influencing factors such as health conditions and illnesses like human immunodeficiency virus and acquired immunodeficiency syndrome (HIV and AIDS), as well as tuberculosis (TB). How the burden of disease influences the occurrence and/or management of ONIHL becomes a key if the goal of hearing conservation programmes (HCPs) is to be achieved within these contexts. OBJECTIVES The purpose of this scoping review was to conduct an investigation on how the burden of disease's influence on ONIHL is reported in literature, with a specific focus on the most prevalent diseases in South African mines - HIV and AIDS and TB. METHOD A scoping review was conducted using the Arksey and O'Malley's framework. A search was conducted in five electronic bibliographic databases and the grey literature. RESULTS The search procured 10 publications, with two specific to ONIHL within the South African context. In addition to the two publications specific to TB and ONIHL, findings revealed a serious gap in the evidence around the scoping review question globally. This obvious lack of investigations into the influence of these two conditions in the South African mining context raises serious implications about the responsiveness, and proactive nature of HCPs within this population. CONCLUSION Considering the burden of diseases on otology and audiology is critical as certain diseases cause hearing impairment either as a primary effect, as a secondary/opportunistic effect or as a side effect of treatment options for that disease. An employee suffering from any such disease with concomitant exposure to hazardous noise levels presents an even bigger challenge to HCPs if such is not taken into consideration in the conception, implementation and monitoring of HCPs.

Precarious transition: a mortality study of South African ex-miners. BMC Public Health 2018; 18:862.

Abstract
Background Despite their burden of a triple epidemic of silicosis, tuberculosis and HIV infection, little is known about the mortality experience of miners from the South African mining industry once they leave employment. Such information is important because of the size and dispersion of this population across a number of countries and the progressive nature of these diseases. Methods This study included 306,297 South African miners who left the industry during 2001–2013. The study aimed to calculate crude and standardised mortality rates, identify secular trends in mortality and model demographic and occupational risk factors for mortality. Results Crude mortality rates peaked in the first year after exit (32.8/1000 person-years), decreasing with each year from exit. Overall mortality was 20% higher than in the general population. Adjusted annual mortality halved over the 12 year period. Mortality predictors were being a black miner [adjusted hazard ratio (aHR) 3.30; 95% confidence interval (CI) 3.15–3.46]; underground work (aHR 1.33; 95% CI 1.28–1.39); and gold aHR 1.15 (95% CI 1.12–1.19) or multiple commodity employment (aHR 1.15; 95% CI 1.11–1.19). Conclusions This is the first long-term mortality assessment in the large ex-miner population from the South African mining industry. Mortality patterns follow that of the national HIV-tuberculosis epidemic and antiretroviral treatment availability. However, ex-miners have further elevated mortality and a very high mortality risk in the year after leaving the workforce. Coordinated action between the mining industry, governments and non-governmental organisations is needed to reduce the impact of this precarious transition.

Abstract
With a growing awareness of the association between extractive industries, the nature of work in remote locations, population mobility and health status, there is a need to advance an evidence-based approach to ensuring the health of migrant and mobile populations, and the home and host communities with whom they interact. Through a narrative synthesis of peer-reviewed and grey literature, this review examines what is known, and the nature of research activity concerning the range of health impacts determined by the social conditions inherent with population mobility alongside mining and extractive industries; and the extent to which health outcomes impact on workers, and home and host communities. While much of the literature reviewed in the study considered health in a traditional disease or illness based approach, it is clear that many risk factors for the health of mobile workers in the sector reflect broader social determinants. To support the mitigation of individual and population vulnerability to infectious disease endemics, consideration of both the etiology and the social conditions that give rise to adverse health outcomes is required, including an improvement to workers' living conditions, the expansion of diagnostic and medical services, and an approach that ensures the right to health for mobile populations. To further improve upon the rich body of research, resources are required to implement robust data collection including epidemiological surveillance, outbreak monitoring and investigation, and the long term tracking of standardized health information at both origin locations and destination communities.

Abstract
Objective: to analyze the meanings produced through the experiences and perceptions of healthcare professionals on the implementation of the strategy of directly observed treatment short course for tuberculosis control. Method: qualitative study carried out in Mozambique with 15 healthcare professionals. Inclusion criteriawerehaving acted in the Tuberculosis Control Program for more than one year, and exercising professional activity at the time of interview. A semi-structured script was used for data collection, and individual interviews were recorded. Results: three discursive units emerged: patient treatment procedures; community health agent and family roles; difficulties in the application of directly observed treatment short course. Conclusion: treatment of tuberculosis requires constant involvement of the family, community, and especially the State in the creation and implementation of personnel training policies and infrastructure improvement.

Abstract
Background The triple epidemic of silicosis, tuberculosis and HIV infection among migrant miners from South Africa and neighbouring countries who have worked in the South African mining industry is currently the target of regional and international control efforts. These initiatives are hampered by a lack of information on this population. Methods This study analysed the major South African mining recruitment database for the period 1973 to 2012 by calendar intervals and demographic and occupational characteristics. Changes in area of recruitment were mapped using a geographic information system. Results The database contained over 10 million contracts, reducible to 1.64 million individuals. Major trends relevant to health projection were a decline in gold mining employment, the major source of silicosis; increasing recruitment of female miners; and shifts in recruitment from foreign to South African miners, from the Eastern to the Northwestern parts of South Africa, and from company employees to contractors. Conclusions These changes portend further externalisation of the burden of mining lung disease to home communities, as miners, particularly from the gold sector, leave the industry. The implications for health, surveillance and health services of the growing number of miners hired as contractors need further research, as does the health experience of female miners. Overall, the information in this report can be used for projection of disease burden and direction of compensation, screening and treatment services for the ex-miner population throughout Southern Africa.

Abstract
Vaccines are an effective public health measure. Vaccination coverage has improved in Africa in the last decades but has still not reached WHO/UNICEF target of at least 90% first-dose coverage for vaccines in the Expanded Programme on Immunization (EPI) implemented in Mozambique in 1979. There are concerns about reliability of vaccination coverage official data from low-income countries, and inequities in vaccine administration. We randomly sampled 266 under-five years children from Taninga, a poor rural area in Southern Mozambique under a Demographic surveillance system and collected data directly from the individual national health cards when available (BCG, DTP/HepB/Hib, Polio, Measles). We also collected data on socio-economic variables through an interview. Overall, only 5% of the participants did not receive all the doses of the vaccines included in the EPI in a timely manner (overall vaccination coverage 95%, 95% CI: 93.5-95.5%). The socio-economic status was homogenously low and no differences were found between vaccinated and unvaccinated children. Vaccination coverage in Taninga was very high, despite the low socio-economic status of the population. The high performance of the EPI in Taninga is an encouraging experience for achieving high vaccination coverage in low-income rural settings.

Abstract
Mineral mining is among the world's most hazardous occupations. It is especially dangerous in southern Africa, where mining activity is a leading cause of HIV and tuberculosis epidemics. Inside mines, silica dust exposure causes long-term pulmonary damage. Living conditions are often substandard; poorly ventilated living quarters facilitate tuberculosis and airborne disease spread, and high rates of alcohol and tobacco use compromise immune responses. Family segregation, a legacy of apartheid's migrational labor system, increases the likelihood of risky sexual activity. Sex trafficking in women increases risks of HIV and other sexually transmitted diseases, and labor trafficking in men through poorly regulated labor brokering impedes access to health care. Labor migration spreads mining hazards to rural, labor-supplying communities. Cross-border care is often inadequate or nonexistent, contributing to significantly greater rates of extensive and multi-drug resistance in miners, ex-miners, their families, and communities. Miners in high-income countries, working for the same transnational companies, do not experience elevated rates of death and disability. Cost-effective interventions can reduce HIV incidence through social housing, curb trafficking of high-risk groups, stop tuberculosis spread through screening and detection, and reduce drug resistance by standardizing cross-border care. Urgent action is needed to respond to mining's staggering, yet avoidable disease toll in sub-Saharan Africa.
