Iran
Risk:
Very High

Health Overview
DO NOT TRAVEL: CRITICAL: Iran is Level 4 with FIVE risk indicators (unrest; terrorism; kidnapping; wrongful detention; other). US-Iran military hostilities ongoing since Feb 28 2025. 'Having a US passport or connections to the United States can be reason enough for detention.' No US Embassy — Swiss Embassy handles limited interests.

Key Health Risks

Very High
Active Military Hostilities (US-Iran since Feb 28 2025)
