Uttar Pradesh native Ramesh Yadav (32), who has been working in Mumbai as a daily-wage labourer for last seven months, was diagnosed with tuberculosis (TB) five months ago. He was admitted to the Sewri TB hospital, but after three months of treatment, he left. Ever since, the hospital has been trying to track him down to bring him back and get him to complete the treatment before he develops drug resistance.
