ABSTRACT
BACKGROUND:
The risk of tuberculosis (TB) disease is higher in individuals with TB infection. In a TB endemic country like India, it is essential to understand the current burden of TB infection at the population level. The objective of the present analysis is to estimate the prevalence of TB infection in India and to explore the factors associated with TB infection.METHODS:
Individuals aged > 15 years in the recently completed National TB prevalence survey in India who were tested for TB infection by QuantiFERON-TB Gold Plus (QFT-Plus) assay were considered for this sub-analysis. TB infection was defined as positive by QFT-Plus (value >0.35 IU/ml). The estimates for prevalence, prevalence ratio (PR) and adjusted risk ratio (aRR) estimates with 95% confidence intervals (CIs) were calculated.RESULTS:
Of the 16864 individuals analysed, the prevalence of TB infection was 22.6% (95% CI19.4 -25.8). Factors more likely to be associated with TB infection include age > 30 years (aRR1.49;95% CI1.29-1.73), being male (aRR1.26; 95%CI 1.18-1.34), residing in urban location (aRR1.58; 95%CI 1.03-2.43) and past history of TB (aRR1.49; 95%CI 1.26-1.76).CONCLUSION:
About one fourth (22.6%) of the individuals were infected with TB in India. Individuals aged > 30 years, males, residing in urban location, and those with past history of TB were more likely to have TB infection. Targeted interventions for prevention of TB and close monitoring are essential to reduce the burden of TB in India.Palavras-chave
