Subject
Prevalence of Silicosis, Pulmonary Tuberculosis, Formal, Informal Sector Miners, Southern Africa
Description
Introduction: Mining in Southern Africa forms a critical role in
employment creation, has a positive influence on the gross national
product and enables earnings in foreign exchange. Formal mining is
conducted by governments or established multinational companies
while informal mining is carried out by individuals or groups that
operate generally without regulation.
Materials and Methods: Data from the Tuberculosis in the Mining
Sector In Southern Africa Project e a Global-Fund Multinational
Project - from 2018 to 2020 was reviewed. Data was sourced from
monthly reports compiled by eleven (11) Occupational Health
Service Centres (OHSCs) across 10 countries in Southern Africa.
Pulmonary tuberculosis (PTB) was diagnosed via a Chest X-ray and/
or a positive GeneXpert test while Silicosis was diagnosed via a
Chest X-ray. Credits to Wits Health Consortium for the data.
Results: 43,618 miners and ex-miners were attended at the OHSCs.
There were 3,067 PTB cases diagnosed with an average yield of 5.6%
(range was 0.5% to 14.4%). Yields above 10% were noted in countries
that have higher informal mining activities. This rate is compared to
a prevalence of less than 1% in the general population. Prevalence of
Silicosis alone was 13% while those that had both Silicosis and PTB
was 9%. These rates are more than double for the informal miners
and ex-miners- 28% and 23% respectively.
Conclusions: There is a higher prevalence of Silicosis and PTB in
miners and ex-miners from informal mines than formal mines.
There is a need to implement controls that reduce silica dust as well
as early screening, diagnosis and management of PTB.
