Total Distance and Radius of Wandering of Patients with COVID19 before the First Final Diagnosis: GPS Tracking Analysis

COVID‑19 is an important problem of the global public health system in the present day. After its first emergence in China,[1] the emergences already occur in more than 160 countries worldwide. Since this disease is a respiratory infection that is easily transmittable for human to human, it is difficult to control. The important consideration should be given to early diagnosis that can lead to proper disease control. In fact, in the early phase, the disease might be asymptomatic and treatment is usually successful.[2] An interesting fact is a disease spreading before the diagnosis of COVID‑19. Some asymptomatic COVID‑19 case before overt illness might wander to several places and cause local transmission.
