Letters | China virus: Hong Kong must declare total shutdown of border to tackle outbreak
- The fact that infected people may display no symptoms for days means just partially closing the border cannot stop the disease from spreading in the city
- Hong Kong’s overstretched health care workers need protection, too

There are cases also of patients without apparent signs of a fever, an obvious sign to detect at the border. The rapid spread of the virus throughout the mainland and the possibility that infected travellers may not display any symptoms point to the dire need to completely shut down Hong Kong’s border with the mainland.
A total border shutdown would be more effective to reduce the risk of mass infection in the population.
According to medical professionals, the coronavirus may incubate for up to 14 days before those infected will start developing symptoms. A complete shutdown would prevent potential carriers and patients coming to Hong Kong, reducing the risk of transmission.
Such a measure can also alleviate the pressure on Hong Kong’s public hospitals, already stretched by the peak flu season. If the Wuhan coronavirus were to spread in the city, hospitals would struggle to handle the overwhelming demand.
