At a tense meeting in Nigeria¡¯s capital, Abuja, health workers pored over drug registers and testing records to gauge whether U.S. aid cuts would unravel years of painstaking work against tuberculosis in one of Africa¡¯s hardest hit countries.

For several days in May, they brainstormed ways to limit the fallout from a halt to U.S. funding for the TB Local Network (TB LON), which delivers screening, diagnosis and treatment.

¡°To tackle the spread of TB, you must identify cases and that is in a coma because of the aid cuts,¡± said Ibrahim Umoru, coordinator of the African TB Coalition civil society network, who was at the Abuja meeting.
