Highlights
Because of the very limited number of patients who can undergo NP swab testing in airborne infection isolation rooms (AIIR), it is difficult to conduct testing on a large scale. It would be beneficial if other specimen types obtained by patients themselves were as effective as NP swabs
We collected nasal and NP swabs simultaneously from 18 patients diagnosed with COVID-19 at different time intervals from symptom onset and diagnosis
Among 5 patients from whom specimens were taken within a week of symptom onset, nasal swabs were positive in four patients (80 %, 4/5) and NP swabs in 3 (60 %, 3/5) (Table 2)
Summary
Hyun Ah Kim, Miri Hyun, Ji Yeon Lee, Sunggyun Park, Namhee Ryoo, Yong Shik Kwon, Jae Seok Park, Jin Young Kim, Jae Cheon Jeon, Kyong Ran Peck. More than 65 % of South Korea’s COVID-19 cases were diagnosed in Daegu [3]. Because of the very limited number of patients who can undergo NP swab testing in AIIRs, it is difficult to conduct testing on a large scale. It would be beneficial if other specimen types obtained by patients themselves were as effective as NP swabs. The diagnosis of COVID-19 was performed by taking nasopharyngeal (NP) swabs and sputum samples concurrently. Owing to an elevated demand for testing following a rapid surge in cases of COVID19, tests were conducted on at least one sample per person.
