2.1. Patient Population
coronavirus disease 2019, fever
CORONAVIRUS DISEASE 2019
Three patients were included in the study, although the initial plan was to enroll a maximum of ten patients. After enrolling three patients, the dramatic rise in cases of coronavirus disease 2019 (COVID-19) in Japan made further enrollment difficult. Specifically, if a patient or the patient’s family had a fever exceeding 37.5 °C, proof of a negative PCR test for COVID-19 was required at the time of the visit to our hospital. Therefore, we decided to terminate enrollment in the study up to the enrollment of three patients.
