London Port Health Authority operates an emergency out of hours service to report infectious disease and illness on board ships and aircraft when Manorway or Denton offices are closed.  Call the standby officer on 07050 389 861​ or email

The London Port Health Authority is responsible for controlling infectious disease within its district. Infectious diseases such as food poisoning, SARS, HIV, Tuberculosis and Noroviruses can be spread by the crew of aircraft and ships and by passengers and other visitors. By their very nature, infectious disease spreads from person to person and can, if not dealt with expediently, infect large numbers of people very quickly and it is the authority's job to investigate suspect and confirmed cases of infectious disease.

Ships and aircraft arriving from outside the UK

The principal legislation applying to ships and aircraft arriving from outside the UK are the Public Health (Ships) Regulations 1979 (as Amended) and the Public Health (Aircraft) Regulations 1979 which reflect the International Health Regulations 2005.
