Outbreak of COVID-19 is an important global public health problem. This new disease originated from Hubei China[1] and spread to more than 40 countries around the world. Thailand is a Southeast Asian that got the disease as the second country in the world.[2] The imported patients increase in number with trend of accelerating increasing.[3] At present (28 February 2020), the accumulated number of COVID-19 is equal to 41. Of these cases, 7 were imported patients (4 males and 3 females). The logistics characteristics of these imported patients are interesting. The local CDC data from a Southeast Asian country that the disease occurred after China are hereby reappraised.

Of these patients, 4 imported from Japan, 2 from China, and 1 from South Korea. All except for 1 case passed disease screening at international port and later diagnosed at hospital when the patients got illness and went to the hospitals. The left 1 case is the case evacuated back from China by local government and diagnosed for infection during quarantine process at a specific place near airport. The logistics analysis on distancing of importation is hereby performed. The analysis shows that average international and intranational importation distances are equal to 3685.4 ± 956.6 and 20.4 ± 15.1 km, respectively. The ratio of transportation between international and intranational distances is between 76.9 and 863.2 times.

Of interest, most documents usually mention for international transportation of disease but the specific next step, intranational transportation, is little mentioned. It can show that there is still a considerable distance of disease transportation within country after imported from aboard.
