The global pandemic of COVID-19 has been devastating and is affecting our daily life. From December to March, the first wave of COVID-19 hit China and now finally passed its peak and largely under control.

Many efforts have been paid to contain the spread of the virus. Besides drastic response such as lockdowns and curfews, newly available technologies are incorporated into government strategies to control the outbreak. Smartphone apps, data analytics and artificial intelligence together make finding and treating people who contracted the virus far more efficient than ever before.
