Russia's war against Ukraine includes a "hidden war against evidence-based medicine" that poses a number of threats on the "health battlefield," said Andriy Klepikov, executive director of the Alliance for Public Health, one of the largest HIV- and TB-focused nongovermental organizations in Ukraine and nearby areas. More so than for HIV or TB treatments, opioid-agonist treatments are most likely to be affected by war-related interruptions, which may have a cascade of consequences for patients with HIV and TB.
