She works at Yong Thai Hang at 24 Cavan Road, a complementary health products shop that primarily serves Chinese tourists. She reported developing sore throat and fever on 29 January, and sought treatment at a general practitioner clinic on the same day. On 30 January, she went to Tan Tock Seng Hospital’s emergency department, and was discharged when her chest x-ray came back negative for pneumonia. She reported that she had not left her home at Jalan Bukit Merah from 31 January to 2 February.

On 3 February, she went to Singapore General Hospital (SGH). As she was diagnosed with pneumonia this time, she was classified as a suspect case and immediately isolated. Subsequent test results confirmed 2019-nCoV infection on 3 February past 11pm.
