Follow standard protective measures, as recommended for this destination, disease or situation. Be aware that advice may change and check for updates.

FCDO advise against travel
Follow Foreign, Commonwealth & Development Office (FCDO) advice. This may mean avoiding non-essential travel, or all travel. Subscribe to the FCDO destination advice for security updates and travel warnings.

Alert categories are based on the situation at the time of publication. They will not be routinely updated unless outbreak information or a news item is updated.

The categories do not replace Foreign, Commonwealth and Development Office (FCDO) travel advice. Travellers should still check the FCDO travel advisories for any country-specific security or safety alerts.
