India is is the global TB epicentre - the country records 2.8 million new tuberculosis cases annually, of which more than 100,000 are multi-drug resistant (MDR), according to the World Health Organization.
"Because India continues to rely heavily on outdated diagnostic techniques, some of which miss about 50% of all TB cases," says Dr Udwadia, who is based in the western city of Mumbai, India's financial capital.
It is our task to reverse the tide." Though treatable, TB kills an Indian every minute and is an engine of poverty, debt and suffering.
"Normal TB is really easy to treat, four drugs over six months at a cost of $5 will almost always cure you," says Dr Udwadia.
drug-resistant TB is a collective indictment of us all." In the last year alone, Dr Udwadia says, 10 million people across the globe have got sick with TB, two million have died of it and about 150,000 patients of drug-resistant TB in India are desperate for a cure.
