No, Covid-19 patients still need to quarantine in Hong Kong. Hong Kong’s Centre for Health Protection (CHP) states that all confirmed cases, close contacts, and asymptomatic patients must complete a 14-day quarantine period. This includes those who have returned from overseas and those who have had close contact with a confirmed case.
Furthermore, the CHP also states that anyone who has been in close contact with a confirmed case must also complete a 21-day quarantine period.
