The US maintains its longstanding Level 4 “Do Not Travel” advisory for Russia, originally driven by security risks, the Ukraine conflict, and detention concerns, and has only reiterated it with health guidance following a single suspected pneumonic plague case tied to a Siberian lab worker’s death in early October 2026. Russian authorities and the WHO assess epidemic risk as low to very low, reporting no confirmed plague spread, negative tests among contacts, and winding down quarantines. US officials, including the State Department and President Trump, have sought transparency from Russia and scheduled bilateral discussion but have not announced or signaled any new plague-specific entry restrictions or formal travel ban. This continuity of existing policy without escalation underpins the strong trader consensus against such a measure materializing in 2026.
