Good news for Hong Kong in the coronavirus battle: we have had five days in a row with no confirmed cases of infection, and some restrictions imposed by the government will soon be lifted . But the Centre for Health Protection has reported at least eight cases of patients testing positive again for the virus after having been released from hospital. Moreover, there may be asymptomatic carriers in the community. Thus, the ray of light that has emerged is offset by fears of the sneaky virus resurfacing. Cases of people who were thought to have recovered from Covid-19 testing positive for the virus again have been reported in South Korea and China. Experts have pointed out that this could be due to the test picking up remnants of the virus or because a test could have returned a false negative or positive. Out of Hong Kong’s more than 800 recovered patients, if even eight have tested positive again, it should worry us. Perhaps it’s natural that, after all these months of boredom and anxiety, people want to relax and turn a deaf ear to unwelcome news and data. It is understandable that people have been flocking to beaches , basking under the long-awaited beautiful sunlight. As for the social movement zealots, who have been dormant for a while, they just can’t help going back to shopping malls to hold rallies and singalongs. All this could well create an opportune moment for the virus to strike again, and the long months in which Hongkongers exercised self-restraint would have gone to waste. My friends, hang in there. Do not give the virus behind Covid-19 a chance to return to harm us.
