Test and trace: lessons from Hong Kong on avoiding a coronavirus lockdown
Governments in Europe and the US can learn from Hong Kong, which has kept infections and deaths from Covid-19 low without resorting to the socially and economically damaging lockdown that the UK and other countries have imposed, scientists say. Hong Kong, with a population of nearly 7.5 million, has had just 715 confirmed cases of Covid-19 infection, including 94 asymptomatic infections, and four deaths. Early in the pandemic, it was thought to be at significant risk because of travellers arriving from mainland China, but since early February the outbreak has appeared to be under control.
The semi-autonomous city took the route that the World Health Organization recommends and embarked on a rigorous programme of testing everyone with symptoms. Those who tested positive were quarantined in hospital. All their contacts over recent days were traced and instructed to self-isolate. In early March, about 400 outpatients and 600 inpatients were being tested every day.
