Situated in a subtropical zone, Taiwan is vulnerable to various tropical diseases. The threat is especially strong because of Taiwan’s thriving international tourism and trade. To prevent cross-border infectious diseases and ensure public health, the government has set up quarantine offices at airports (Songshan, Taoyuan, Taichung and Kaohsiung), seaports (Keelung, Suao, Taipei, Taichung, Mailiao, Kaohsiung, and Hualien), and the three terminals (Kinmen, Matsu and Makung) of the “Mini Three Links” with China.

To meet the International Health Regulations 2005 (IHR2005) requirements and prevent cross-border infectious diseases by aircraft and ships, the Taiwan CDC has revised the Regulations Governing Quarantine at Ports. These regulations authorize the quarantine units to take all necessary quarantine measures against inbound ships, aircraft, their crew, passengers, and cargo for national security and public health protection.
