Month in Focus looks at some of the work undertaken by MSF over the previous month. This month's video looks at the development of a new diagnostic test for TB, the problem of insufficient healthcare services in south Sudan, a large scale meningitis vaccination programme in Mali and the problem of obstetric fistula in Burundi. And finally to Delhi, where at the beginning of March thousands of people living with HIV/AIDS marched to defend their right to affordable anti-viral drugs.
