This new WHO guidance sets out recommendations to ensure the continuity of opioid agonist maintenance treatment (OAMT) during crises such as disease outbreaks, conflict, and other emergencies. Recognizing OAMT as an essential, life-saving health service, the report emphasizes that treatment must remain uninterrupted and fully integrated within national health systems. It outlines contingency measures to prevent disruptions, including early coordination with affected communities, expanded take-home treatment options, overdose prevention through naloxone distribution, and strengthened psychosocial support to maintain access and continuity of care for people who use drugs.
