That number could increase dramatically because of the Trump administration’s cuts to foreign assistance, according to a new study co-authored by Ditiu . In particular, it’s hard to know precisely how much funding cuts translate to service disruptions, especially since countries will have varying responses to the cuts. That allowed them to estimate the impact of U.S. funding cuts for 26 high burden countries. And in the worst-case scenario, countries never get fully back on track, and their TB control programs operate at permanent deficits. Such efforts benefit the hardest hit countries, but also wealthier countries that have forgotten the threat of TB, says Ditiu.
