New Delhi: A new research has claimed that smoking could be responsible for 40 million excess deaths from tuberculosis between 2010 and 2050.
According to the study led by Dr Sanjay Basu from the University of California, there will be 18 million more cases worldwide between 2010 and 2050 because smoking increases the risk of contracting TB.
The authors say that smoking tobacco is a TB risk factor and nearly one fifth of the world`s population smokes, and that most cigarettes are smoked in countries with high TB prevalence, where the tobacco industry has expanded its market.
For the study, the researchers developed a mathematical model to investigate the issue and in their analysis, found that smoking may have a substantial impact on future TB rates because a moderate increase in individual risk translates into a large population-level risk because so many people smoke.
The results show that from 2010 to 2050 worldwide smoking could lead to 40 million excess TB deaths and that if the current smoking trends continue, the number of excess TB cases could rise from 256 to 274 million in total.
