Screening and symptom-triggered testing accounted for most detections, with 44.7% of symptom-investigated cases symptomatic. No new cases were confirmed solely from exposure during the re-positive period, while three newly confirmed cases among monitored contacts had links to Shincheonji or household contacts. Re-positive proportions varied by group, testing timing averaged 44.9 days post-onset and 14.3 days after discharge, cell culture was negative, and neutralizing antibodies were detected from the first serum.","SUMMARY  \n○ Epidemiological investigation and contact investigation have been completed for 285 (63 .8%) of the total 447 re-positive cases (as of 15 May) .  \n○ 59. 6% were tested as a screening measure, and 37. 5% were tested because of symptom onset. Of the  \n284 cases for which symptoms were investigated, 126 (44 .7%) were symptomatic.  \n○ From the 285 re-positive cases, a total of 790 contacts were identified (351=family; 439=others) . From the monitoring of contacts, as of now, no case has been found that was newly confirmed from exposure during re-positive period alone.  \nNOTE  \n○ In response to reports of multiple cases testing positive for SARS-CoV-2 after being discharged from isolation, on 14 April, KCDC began managing such cases with measures similar to those for confirmed cases, while further investigation, research and analysis continued. On 18 May, KCDC announced the findings and the conclusions of the advisory committee. The protocols for the management of such cases will be revised accordingly.  \n- Based on the findings, starting 0:00 of 19 May, KCDC has stopped applying the previous protocols for the management of confirmed cases after discharge from isolation and for the management of re-positive cases. Under the new protocols, no additional tests are required for cases that have been discharged from isolation.  \n- Reporting and investigation of re-positive cases and investigation of contacts of re-positive cases will be continued as before for the purposes of research and investigation. However, based on experts’recommendations, the terminology for referring to such cases will be changed from “re-positive” to“PCR re-detected after discharge from isolation”.  \n○ In this document, “discharge” refers to discharge or release from isolation of confirmed cases after recovery and meeting all discharge criteria (in accordance with KCDC guidelines) .  \n○ “Re-positive cases” are cases that test positive for SARS-CoV-2 after being discharged from isolation.  \nPROPORTION OF RE-POSITIVE CASES  \n○ Depending on the group, 25.9-48.9% of cases tested positive again after discharge.  \n\n| Region | Group | Tested (n) |  | Re-positive (n) | (%) |\n| --- | --- | --- | --- | --- | --- |\n| Sejong City | All confirmed cases | 27 |  | 7 | 25.9% |\n| Daegu City | Confirmed cases related to schools (school staff, students) | Total | 195 | 53 | 27.2% |\n|  |  | School staff | 47 | 6 | 12.8% |\n|  |  | Students | 148 | 47 | 31.8% |\n| Gyeongbuk Province | Confirmed cases of Pureun Nursing Home | 47 |  | 23 | 48.9% |\n\nTIMING OF TESTING RE-POSITIVE  \n○ On average, it took 44.9 days (range: 8-82 days) from initial symptom onset date to testing positive after discharge. (Based on 226 cases symptomatic at the time of initial confirmation)  \n○ On average, it took 14.3 days (range: 1-37 days) from discharge to testing positive. (Based on 285 cases)  \nSYMPTOMS AND TESTING OF RE-POSITIVE CASES  \n○ 59. 6% of the re-positive cases were tested for screening, regardless of symptoms.  \n○ 44.7% of re-positive cases had symptoms such as coughs, sore throat, etc.  \n(n,%)  \n\n|  |  | Re-positive cases |  |\n| --- | --- | --- | --- |\n| Total |  | 285 |  |\n| Reason for testing | Symptoms present | 107 | (37.5) |\n|  | Investigation | 170 | (59.6) |\n|  | Requested\u003Cbr>(by self or guardian) | 8 | (2.8) |\n| Symptoms\u003Cbr>*284 cases for which symptoms were checked | Symptoms present | 126 | (44.7) |\n|  | Symptoms absent | 158 | (56.6) |\n\nFINDINGS FROM MONITORING OF CONTACTS OF RE-POSITIVE CASES  \n○ For the 285 re-positive cases investigated, 790 contacts were found in total. Minimum 14-day monitoring found 27 of the contacts to be positive, 24 of which were cases that were previously confirmed.  \n○ There were 3 newly confirmed cases from the 790 contacts of re-positive cases.  \n- Other than their exposure to the re-positive cases during their respective re-positive period, all of the  \n3 newly confirmed cases had history of contact with Shincheonji religious group or a co","cbCaihRxg070VsKU","https://ap.wps.com/l/cbCaihRxg070VsKU","pdf",180806,2,1,5,"English","en",105,"# Summary\n## Proportion and timing of re-positive testing\n## Symptoms and testing reasons\n## Findings from contact monitoring\n## Virus isolation and laboratory results\n## Notes on management protocol changes","[{\"question\":\"How many re-positive cases were included and what testing purposes were most common?\",\"answer\":\"Investigations covered 285 re-positive cases (63.8% of 447 total cases as of 15 May).
