        In late 2019, the novel coronavirus 2019 (COVID-19) outbreak was first identified in Wuhan, China, and subsequently spread worldwide. By July 11, 2020, the number of confirmed COVID-19 cases reached 12,881,555 (including 599,146 deaths) in 187 countries/ territories. The pandemic has not reach its peak yet. The situations of epidemics in the United States, Central and South Americas, and South Asia were still serious. Some countries faced re-surging epidemic after lifting restrictions. In Taiwan, the first imported case and the indigenous case were reported on January 21, and 28, respectively. As of July 12, the cumulative number of confirmed cases was 451, including 360 imported cases, 55 indigenous cases, and another 36 cases of naval crew members aboard the Panshi fast combat support ship. Currently the COVID-19 cases in Taiwan were still sporadic imported cases. No locally-acquired case was found for more than 8 weeks. Based on the current epidemic status, the risks of imported cases are still high. The high transmissibility of the virus and the potential of community outbreak remained as a threat to Taiwan's health system and society. Therefore, the overall risk of COVID-19 is considered high domestically.

        Since December 21, 2019, on-board inspection had been implemented on direct flights from Wuhan, China, marking the beginning of boarder quarantine challenges in respond to COVID-19 pandemic. In line with the development of the international epidemic, the Central Epidemic Command Center gradually expanded entry restrictions and post-entry quarantine requirements. Since March 19, 2020, all foreign nationals had been prohibited from entering Taiwan. Passengers eligible for entry were required to undergo home quarantine for 14 days. Upon arrival, passengers were required to declare their symptoms and travel history, and to receive fever screening and health assessment. Throat swab specimens were collected from those who presented symptoms at the airport or in the hospital, and then these passengers stayed in a centralized quarantine facility to wait for testing results. In addition, aiming at reducing risks originated from crowds and frequent movement, only aircrafts from five airports in China were allowed to enter Taiwan. Also, all connecting flights were suspended, and cruises and cross-strait passenger liners were banned from calling at ports of Taiwan. For front-line officers at ports of entry, health monitoring and protection guidelines were developed to protect their safety. In order to ensure safety and security of air and sea transport, the competent authorities in charge of transportation have established an epidemic prevention and management mechanism for air and sea transport respectively.
        Over 184,000 home quarantine notices had been issued by border quarantine authorities. More than 80% of the inbound travelers completed the declaration via Entry Quarantine System, greatly improving timeliness and accuracy of information required for further epidemic prevention and control in community. With on-board quarantine and health surveillance system for entry, not only the first confirmed case in Taiwan, but also more than one-third of imported cases were detected through border quarantine, sparing more capacity for domestic response and preparedness for medical resources and medical systems and therefore alleviating pressure on epidemic prevention and control in the community. Despite continuous and serious epidemic and significant challenges ahead, Taiwan keeps on implementing various quarantine measures in accordance with the principle of “strict risk control at border “to comprehensively protect border security.

        COVID-19 is an emerging infectious disease occurred in Wuhan, China at the end of 2019. The epidemic began to spread in early 2020 and had become a global pandemic. In order to prevent the disease from entering the community and causing continuous transmission, Taiwan had successfully curbed the spread of COVID-19 through rigid community defense lines. Relevant measures included strengthening the notification of suspected cases, launching an expanded community surveillance program, detecting submerged cases effectively, and following by prompt isolation and adequate treatment, monitoring cases progression throughout the whole medical process. Furthermore, to implement home isolation and home quarantine policy, the Central Epidemic Command Center (CECC) established appropriate tracking and following up systems on persons at risk of infection with smart technology and inter-ministerial cooperation. In addition, the CECC published epidemic prevention guidelines and provided advices for crowded places or activities to strengthen epidemic prevention at those with high risks of infection. Moreover, through multiple channels and platforms, the CECC established communication with the public regarding risks of infection and raised the public’s awareness of epidemic prevention among our people. Thanks to the collective efforts of the public and strict border controls, the epidemic was under stable situation. The CECC substantially lifted the restrictions since June 7, so that the public and industries could return to normalcy. Lastly, to be prepared for the future border controls adjustments, personal health behaviors must be cultivated and rooted deeply in our daily lives. In addition to closely monitoring the epidemic situations and trends, The CECC continues to encourage our people to implement the "Epidemic New Life Movement" and timely adjust the epidemic prevention strategies according to the epidemic status of COVID-19. Most importantly, the CECC will make every efforts to reduce the risks of community transmission and protect the health of our people
