中央流行疫情指揮中心今(21)日表示，因近期國內境外移入個案數攀升，將往回追溯3月8日至18日間，自美國、東亞國家入境後曾就醫者約3,000筆，通知即刻起居家檢疫，並進行 COVID-19(武漢肺炎)病毒檢驗。

指揮中心進一步表示，已主動勾稽健保系統，調查這段期間自上述國家返國後曾就醫，並有上呼吸道症狀者，將透過簡訊通知該民眾即刻配合居家檢疫，同時主動聯繫地方衛生局或1922防疫專線，安排相關採檢措施；若民眾入境後曾就醫，但尚未收到簡訊，亦請主動聯絡當地衛生局及配合相關措施。

On March 21, the Central Epidemic Command Center (CECC) announced that travelers who arrived in Taiwan from the United States and East Asia between March 8 and March 18 and developed symptoms in the said period of time are required to undergo home quarantine, and be tested for coronavirus disease 2019 (COVID-19) for retrospective investigation. The CECC indicated that it has linked related data to the National Health Insurance (NHI) system in order to identify individuals who sought medical attention and had upper respiratory symptoms during the specified time period (3000 records) after returning from these countries. The CECC will send text messages to symptomatic persons to remind them to undergo home quarantine, and to voluntarily contact the local public health bureau or health agencies at 1922, the Communicable Disease Reporting and Consultation Hotline, which will arrange COVID-19 testing. Inbound travelers who sought medical care but haven’t received any text messages from health agencies should voluntarily contact the local public health bureau and follow related measures.
