The Outbound Travel Alert (OTA) System aims to help people better understand the risk or threat to personal safety in travelling to 88 countries/territories that are the more popular travel destinations for Hong Kong residents (HKRs). When there are signs of threat in a place that may affect the personal safety of HKRs, the Security Bureau will assess and consider the need to issue an OTA taking into account factors such as the nature (e.g. whether it is targeted at travellers), level and duration of the threat. Should there be public health reasons, based on the alert level as advised by the Food and Health Bureau, the Security Bureau will issue an OTA on countries/territories seriously affected by infectious diseases to help the public better understand the possible health risks.
