The Hong Kong authorities announced this Monday that they will tighten security and containment measures against the coronavirus pandemic after 50 new cases were found on the last day.
The local government, which has warned that more than 30 percent of infections cannot be traced, has met to discuss what containment measures should be used to prevent the virus from spreading further.
The main epidemiologists in the Chinese special administrative region have found differences in containing a possible third wave of infection. Some want to implement restriction and distance measures again, while others doubt their long-term sustainability.
For their part, the Macau authorities have introduced new restrictive measures, so that everyone from Hong Kong must submit a medical certificate stating that they have tested negative for COVID-19.
Signs of a third wave of contagion started in Hong Kong last week when new outbreaks were confirmed in East Kowloon and Sha Tin. Between March 5 and 11, 211 cases were confirmed, including 143 local broadcasts. It is not known where 31 percent of them come from, government data shows.
