Risk of tuberculosis in public transport sector workers, Lima, Peru
OBJECTIVE: To estimate TB incidence rates in patients of a health micro-network, and the percentage of transport sector workers among TB and multidrug-resistant TB (MDR-TB) patients.
DESIGN: Crude and indirect standardised incidence rates of TB were calculated from an exhaustive analysis of all clinical histories of incident patients in a health micro-network between 1 January 2007 and 30 June 2008. The percentage of transport sector workers and the association between MDR-TB and working in the transport sector were analysed.
RESULTS: Standardised incidence rates for transport sector workers are 2.7–4.5 times higher than those in the total working-age male and global population of the micro-network studied. The association between TB and transport occupation and MDR-TB and transport occupation is high (respectively OR 3.06, 95%CI 2.2–4.2 and OR 3.14, 95%CI 1.1–9.1).
CONCLUSION: These results indicate that the use of informal public transport is a risk factor for TB infection and an occupational risk in countries with characteristics similar to those in Peru.
