  The Korea Disease Control and Prevention Agency (KDCA) operates the coronavirus disease 2019 (COVID-19) information management system and uses it to respond to COVID-19. As the number of confirmed COVID-19 cases surged after the introduction of the Omicron variant into the Republic of Korea, it became necessary to change the quarantine response strategy. For a rapid and efficient epidemiological investigation, the confirmed case report form (the mobile-based and selfreported) was introduced, which simplified survey questions. Since then, the COVID-19 case reporting form database (Cov-CRF-DB) has been created using data from the COVID-19 information management system. In order to timeously utilize the Cov-CRF-DB, the secondary attack rates (SAR) monitoring system for household contacts was updated with monitoring indicators. The number of confirmed cases over the last four weeks (September 4–October 1, 2022) was 1,250,651, of which 676,814 were household contacts. The number of index patients with the earliest confirmation date in the household was 249,318, and the number of confirmed household contacts of those index patients was 653,628, with a 28.4% SAR. In future, confirmed patients and their household contacts will be monitored to prevent secondary infection and the information will be shared with the relevant institutions. If required, sub-groups will be further researched.

  Anaplasmosis is a tick-borne zoonotic disease, the causative agent of which is Anaplasma phagocytophilum. This study analyzed the positivity rate, sex, age, clinical findings, and time period of domestic anaplasmosis infection based on the results of confirmed diagnosis of anaplasmosis commissioned by the Korea Disease Control and Prevention Agency from 2019 to 2021. In the past three years, a total of 2,024 samples have been referred for suspected anaplasmosis infection, and the number of patients who were finally confirmed positive were 3.4% (31 people) in 2019, 5.6% (31 people) in 2020, and 8.7% (48 people) in 2021. 64.5% (71 female) and 71% (78 people) were identified in the age group over 70 years of age. Clinical findings in patients confirmed to be anaplasmosis positive were based on fever (84%) symptoms, but the highest positivity rate was seen in patients (41.3%) who had both fever and decreased platelet counts. The Seoul area had the largest number of requests for domestic anaplasmosis samples, but the Jeonbuk region showed the highest distribution of anaplasmosis patients with a positivity rate of 25.5%, and it was confirmed that they were concentrated from May to July. Anaplasmosis patients have confirmed a high positivity rate in samples that fully consider the patient's clinical findings such as fever, decreased platelet count, outdoor activity, and tick bite. This study expected to be used as basic data for surveillance, spread, and management of zoonotic diseases.
