Abstract

Objectives
To describe and evaluate epidemiological investigation results and containment measures implemented in Busan, where 108 cases were confirmed with coronavirus disease 2019 (COVID-19) between February 21, 2020 and March 24, 2020.

Methods

Any individual who tested positive for COVID-19 was classified as a confirmed case. Measures were taken to identify the source of infection and trace and quarantine contacts. Serial intervals were estimated and the effective reproduction number was computed.

Results

Of the total 18,303 COVID-19 tests performed between January 16, 2020 and March 24, 2020 in Busan, 108 yielded positive results (positive test rate, 0.6%). All confirmed cases were placed in isolation at hospitals. Of the 108 confirmed cases, 59 (54.6%) were female. The most common age group was 20-29 years with 37 cases (34.3%). Regarding symptoms at the time of diagnosis, cough (n=38, 35.2%) and fever (n=34, 31.5%) were most common; 12 cases (11.1%) were asymptomatic. The source of infection was identified in 99 cases (91.7%). A total of 3,223 contacts were identified and quarantined. Household contacts accounted for 196, and the household secondary attack rate was 8.2% (95% confidence interval [CI], 4.7 to 12.9). The mean serial interval was estimated to be 5.54 days (95% CI, 4.08 to 7.01). After February 26, (Rt) remained below 1 in Busan.

Conclusions

The early containment strategy implemented in Busan shows that control is possible if outbreaks are of limited scope. In preparation for future outbreaks, public health and healthcare systems should be re-examined and put in a ready state.

Summary

2월 21일부터 3월 24일까지 부산시에서 보고된 108명의 코로나바이러스감염증-19 (코로나19) 확진 환자의 역학 조사 결과와 관리 조치를 기술하고 평가하였다. 초기에는 A 교회 클러스터와 다른 지역에서 유입된 사례로 인해 급격한 환자 증가가 있었고 이후 접촉자를 중심으로 2차 유행을 보였다. 2월 26일 이후 부산 지역의 Rt가 1보다 낮은 값을 보여 전파가 통제되고 있음을 알 수 있었다. 부산에서 초기 containment 전략을 시행한 결과 제한된 발생 규모인 경우 통제가 가능하다는 점을 확인하였다. 이후 발생할 유행에 대비해 적극적으로 공중보건 및 보건의료 체계를 정비하고 준비해야 할 것으로 생각된다

Abstract

Coronavirus disease 2019 (COVID-19), which causes severe respiratory illness, has become a pandemic. The World Health Organization has declared it a public health crisis of international concern. We developed a susceptible, exposed, infected, recovered (SEIR) model for COVID-19 to show the importance of estimating the reproduction number (R0). This work is focused on predicting the COVID-19 outbreak in its early stage in India based on an estimation of R0. The developed model will help policymakers to take active measures prior to the further spread of COVID-19. Data on daily newly infected cases in India from March 2, 2020 to April 2, 2020 were to estimate R0 using the earlyR package. The maximum-likelihood approach was used to analyze the distribution of R0 values, and the bootstrap strategy was applied for resampling to identify the most likely R0 value. We estimated the median value of R0 to be 1.471 (95% confidence interval [CI], 1.351 to 1.592) and predicted that the new case count may reach 39,382 (95% CI, 34,300 to 47,351) in 30 days.

Abstract

OBJECTIVES
Since the first novel coronavirus disease 2019 (COVID-19) patient in Korea was diagnosed on January 20, 2020, 30 patients were diagnosed until February 17, 2020. However, 5,298 additional patients were confirmed until March 4, 2020. Therefore, our objective was to estimate the reproduction number (R) and evaluate the effectiveness of preventive measures.

METHODS

A COVID-19 transmission model (SEIHR) was established to suit the Korean outbreak. The number of daily confirmed cases in Daegu and North Gyeongsang Province (NGP), the main area of outbreak, was used. The first patient’ symptom onset date in the Daegu/NGP outbreak was assumed as January 22, 2020. The R according to the start date of the effect of preventive measures was estimated.

RESULTS

The estimated R in Hubei Province, China, was 4.0281, whereas the estimated initial R in Korea was 0.555, but later in Daegu/NGP, the value was between 3.472 and 3.543. When the transmission period decreases from 4-day to 2-day, the outbreak ends early, but the peak of the epidemic increases, and the total number of patients does not change greatly. It was found that, if transmission rate decreases, the outbreak ends early, and the size of the peak and the total number of patients also decreases.

CONCLUSIONS

To end the COVID-19 epidemic, efforts to reduce the spread of the virus, such as social distancing and wearing masks, are absolutely crucial with the participation of the public, along with the policy of reducing the transmission period by finding and isolating patients as quickly as possible through the efforts of the quarantine authorities.

Summary

Korean summary
수학적 모델링을 통하여 코로나-19 감염재생산수( R )와 대구, 경북의 유행 규모와 유행 종료 시점 등을 예측해보았다. 그 결과 중국 후베이성의 R=4, 한국 초기 30일간의 유행은 R=0.5, 대구/경북의 3월 4일까지의 유행은 R=3.5 수준으로 나타났다. 하지만 방역당국의 적극적인 코로나-19검사로 환자들의 감염전파기간이 짧아지고, 국민들의 마스크 쓰기, 사회적 거리두기 등의 감염 예방조치 적극 참여로 전파율이 낮아져 5월 1일경에 하루 환자 1명 수준으로 예측되었다.
