The head of the World Health Organization on Monday dismissed complaints from countries complaining that contact tracing is too difficult to implement as a control strategy for the coronavirus pandemic as “lame.” The U.N. health agency has repeatedly advised countries that shutting down their COVID-19 outbreaks requires having a strong contact tracing program in place, a labor-intensive process of tracking down contacts of people with coronavirus to ensure those at risk isolate themselves. Britain had vowed to have a “world-class” contact tracing system in place earlier this month.
