Surabaya (ANTARA) - Head of the East Java Provincial Health Service Dr. Erwin Astha Triyonno broke down the chronology of the finding of the COVID-19 variant, Omicron, in the region.

The first case of Omicron was detected in a Surabaya resident, with the initials as TYC, after a five-day vacation with her husband, with the initials as SJJ, who used a private vehicle.

"The East Java Health Service has detected a confirmed Omicron patient based on the results of the whole-genome sequencing (WGS) examination that came out on January 2, 2022." Triyonno stated on Monday.

During TYC's holidays from December 20, 2021, to several tourist attractions, she spoke of always using the PeduliLindungi application. However, after returning home on December 25, TYC experience soreness in her throat.

On December 28, TYC checked herself into a hospital and was advised to do an RT-PCR swab test, whose result came positive on the same day, with a CT Value of 26.

Thereafter, on December 30, the results of her S-gene Target Failure (SGTF) came positive for the K417N (Delta Plus) variant and the probable Omicron variant. Later on, she was directed to undergo isolation at a hospital in Surabaya while awaiting the WGS results to come out.

Furthermore, the Surabaya Health Service immediately conducted tracing with RT-PCR swab testing on TYC's close contacts: residents in the same house, her families, and 10 of her neighbors. The result showed that one family member was confirmed positive (TGO), while the other three family members and the rest of the neighbors had tested negative.

Meanwhile, the TGO patient is undergoing self-isolation at a different house along with other families under close supervision as well.

The Surabaya Health Office had monitored TYC's health condition. She confirmed to not having any symptoms and being in a good condition.

"We will keep monitoring the quarantine of close contacts and will repeat the RT-PCR test on them," Triyonno noted.
