Apart from those preventive measures, conducting mass coronavirus testing in key areas and maintaining temperature checks in public spaces can also help authority nip new infections in the bud.

Wuhan, the epicenter of China's coronavirus outbreak, tested nearly 10 million residents citywide after lifting its lockdown. China's health authority has also scaled up testing in border areas such as Mudanjiang in the northeast, where the risk of imported cases is high.

Temperature screening is stringently conducted on a broader scale nationwide. People are required to have their temperature taken while entering offices, schools and universities, restaurants, subway stations, gyms, hospitals, and communities, among others.

While taking all those measures, going digital can make epidemic prevention and economic recovery much easier.

In cooperation with digital tech giants, local governments have launched health codes on smartphone apps such as Wechat and Alipay to rate a user's risk of infection. Meanwhile, health authorities have also pushed for online diagnosis and treatment services as well as drug delivery services to reduce non-essential outdoor activities.
