The Public Health Agency of Canada upgraded its travel-health notice on diphtheria to “Level 1 – Practise health precautions” on 4 February, citing expanding outbreaks in six African countries and a global shortage of antitoxin. (travel.gc.ca)
While the advisory does not restrict travel, it urges Canadians—particularly those unvaccinated or travelling with young children—to verify immunisations at least six weeks before departure. The notice highlights challenges such as low vaccination coverage, concurrent disease outbreaks and limited medical resources in Chad, Mali, Mauritania, Nigeria, Somalia and South Africa.
Before arranging itineraries, travellers and mobility managers may also benefit from professional assistance with entry requirements. VisaHQ’s Canadian portal (https://www.visahq.com/canada/) offers up-to-date visa information, electronic applications and document courier services, streamlining the paperwork while you focus on pre-travel health precautions.

For international assignees and business travellers, the update serves as a reminder that corporate duty-of-care obligations extend well beyond visas and work permits. Mobility managers should incorporate diphtheria boosters into pre-departure medical check-lists and brief travellers on contingency plans, given the scarcity of antitoxin in destination countries.
The advisory also dovetails with Canada’s wider push for preventive travel medicine ahead of the 2026 FIFA World Cup, when cross-border movement is expected to surge. Companies with operations in Africa should liaise with insurance providers to confirm emergency-evacuation coverage in regions experiencing health-care strain.
Although the notice is the lowest on the government’s three-tier scale, failure to heed vaccination advice could expose employers to liability should staff contract vaccine-preventable diseases while on assignment.
