Thailand is the second country that was affected by this new disease.[2] Focusing on clinical presentation of this new coronavirus infection, the main clinical presentation is acute febrile illness with pulmonary complications.

In clinical hematology, the effect of the infection is reported. Leukopenia is a common clinical blood picture.[3,4] Regarding the alteration of coagulation system, decreased platelet count and prothrombin time is observable.[3,4] In fact, this is similar observation to that seen in a previous emerging coronavirus infection, Middle East respiratory syndrome.[5] Nevertheless, there is still no report regarding hemorrhagic problem in the patients with COVID-19. Here, the authors would like to present observation from Thailand on 41 patients (4 males and 37 females, age between 7 and 74 years) with COVID-19 in Thailand (based on most update data at February 29, 2020).
