HONG KONG: Surveillance indicators, including respiratory specimen detection rate and viral load from sewage surveillance, marked an increase in Covid-19 activity in Hong Kong in the past few weeks, prompting government health advisers to call for boosting vaccination, especially for the high-risk priority groups.
The Scientific Committee on Vaccine Preventable Diseases and the Scientific Committee on Emerging and Zoonotic Diseases under the Centre for Health Protection made the call after a meeting on Tuesday (July 16).
