Officials said around 46,300 people are currently under self-quarantine. The number ballooned after the government began enforcing 14-day quarantines on all passengers arriving from abroad on April 1 amid worsening outbreaks in Europe and the United States.
Although quarantined individuals have been required to download a tracking app that alerts authorities if they leave their homes, some of them have been caught slipping out by leaving their phones behind.
The wristbands will communicate with the phone apps through Bluetooth and alert authorities when people leave home or attempt to remove the bands.
