Measles outbreak in American Samoa: new entry requirements for Samoa

The American Samoa Department of Health reports a measles outbreak. As of 27 April 2023 there have been 49 suspected cases and 2 confirmed cases.

In response to the outbreak, the Ministry of Health of Samoa has introduced new requirements for arrivals from American Samoa.

All travellers from American Samoa must be vaccinated with a measles vaccine before entering Samoa. This must be certified. Full details are given on the Samoa Ministry of Health website.

Advice for Travellers

Measles is most common in young children, but all ages are at risk if they have not been fully vaccinated or had prior measles infection.

Travel may increase an individual’s risk of exposure to measles virus, and facilitate the spread of disease to unvaccinated and susceptible populations. The travel consultation provides a valuable opportunity to ensure individuals are protected against measles, mumps and rubella (MMR) viruses. Two doses of MMR vaccine, at least one month apart, are required to give adequate protection.

Vaccination is required before arrriving in Samoa from American Samoa, but in general consider vaccinating:

• all travellers who have not previously had two doses of MMR vaccine or prior measles infection
• travellers visiting friends and relatives (VFRs), and/or mixing closely with the local population
• younger children who have not yet been fully immunised

For children, first and second doses of MMR vaccine can be administered earlier than they would routinely be given within the UK Vaccination Schedule (2 doses of MMR vaccine around 12-13 months, and before starting school at around 3 years 4 months of age).

• MMR vaccine can be given from 6 months of age when early protection is required
