The Korean government had a meeting discussing whether the government should mandate people in quarantine (currently around 90,000) to wear an electronic anklet or a bracelet to track their location.
The necessity of such measure, according to the article, is due to the fact that some people in quarantine left their cellphones in hotels and roamed around the city — a factor that made virus tracking difficult. However, measures in mandating citizens who are not criminals to wear electronic anklet / bracelet is raising human rights concerns.
