Dear Editor,

Coronavirus disease-2019 (COVID-19) is an emerging global public health problem. The disease first appeared in China,[1] and it has already affected more than 45 countries around the world. The importation and exportation of disease is a big challenge for disease control and prevention.[2] Here, the authors would like to share observations on COVID-19 identification during international transit. The specific situation in Thailand, the second country affected by COVID-19, is referred to. At present, as of 21 March 2020, there are already 411 COVID cases in Thailand. Of akk 411 cases existed in Thailand, of which 50 are foreigners (26 from China, 4 Denmark, 3 Japan, 3 UK, 2 Italy, 2 USA, 2 Canada, 1 Singapore, 1 French Guiana, 1 Belgium, 1 France, 1 Pakistan, 1 Myanmar, 1 Malaysia and 1 Switzerland). Of these patients, 15 cases were identified post immigration and 1 was detected at international transit unit.

The specific case is a 22-year-old male that was identified during transit, who is a Chinese patient who took a connecting flight in Thailand on the route from Iran to China. The patient had a high fever and detected at the transit unit at the international airport, and then quarantined and the disease was identified. This report can show that the disease from a foreigner might be detected at any position on the international travel route. For our setting, the disease is usually detected when the immigration problem was already complete and the patient already entered into the country for a period of time before the disease could be diagnosed. The specific case identified at the transit unit can show that the disease screening on an international path, at any point, emigration, immigration or transit unit, should be used for the prevention of disease spreading via international travel.
