The sample submitted by RTHK host Joyce Yeung was contaminated, and she was ruled a false positive case, while guests of a birthday party that were sent to the quarantine center because of her would soon get to leave. Yeung was among some 180 guests who attended the birthday party of Witman Hung Wai-man on Monday. She tested preliminary positive on Friday, but her case was ruled a false positive case on Saturday. He continued that the virus that tested positive was from the vaccine, but not the coronavirus spreading in the city due to the differences in the genetic sequencing. A dozen birthday party guests sent to the quarantine center because of Yeung's case would then be arranged to leave, controller of the Center for Health Protection Edwin Tsui Lok-kin said.
