Despite being preventable and curable, tuberculosis remains a major global health threat, infecting over 10 million people and claiming more than 1 million lives every year. In this episode of Communicable, hosts Angela Huttner and Navaneeth Narayanan discuss tuberculosis with experts Lorenzo Guglielmetti of Doctors without Borders and Olha Konstantynovska of Kharkiv National University, Ukraine.
