Abstract

Objectives:

This study aims to report a successful systematic quarantine of coronavirus disease (COVID-19) to detect Omicron, a new variant of concern, among 2 cargo ships in the Morowali seaport, Indonesia.

Methods:

An international standard entry point protocol had been followed in this study for all crew. Rapid diagnostic tests and whole-genome sequencing (WGS) tests have been conducted to identify Omicron, the variant of concern. Individual characteristics, laboratory result, and vaccine status were collected in this study.

Results:

On December 9 and 18, 2021, there was an increase of 21 and 22 new cases, respectively, from 2 ships in the seaport. Both ships came from abroad, 43 new cases with a positivity rate increase from 0 to 13.4% and 13.7% within 2 weeks. A polymerase chain reaction (PCR) examination was carried out on all crews and obtained results 21 of the 22 positive COVID-19 crew (95.5%). The monitoring results showed that there was no fever in the entire crew, no symptoms of cough, runny nose, shortness of breath, and other symptoms pointing to COVID-19.

Conclusion:

Systematic quarantine has successfully contained the large clusters of COVID-19 in the crews of 2 ships and prevented further outbreaks in the local community.
