In last September, Kelly Cheung (張曦雯) and her boyfriend, Mark attended their good friend’s wedding in America and returned to Hong Kong after 2 months later. Subsequently, she disclosed she was infected at Los Angeles and recovered quickly, since having two vaccinations. Kelly said: “I am staying at home during the holidays. We believe it is important to wear face masks, use hand sanitiser and go for vaccination. Unfortunately, it is still hard to prevent from happening. This year, I feel grateful to stay healthy and none of my loved ones is infected other than me. Until now, I am clueless about the infection and it is essential to remain vigilant. Wishing everyone to stay safe and healthy.”
