Fears of mass outbreak as SKorea virus cases rise

South Korea's Centers for Disease Control and Prevention has warned of the possibility of a further mass outbreak of the coronavirus, as dozens of new cases have been reported in a resurgence mostly concentrated around the capital, Seoul. Government officials are resisting calls to reimpose stronger social distancing measures out of concern they'll hurt a fragile economy. But the CDC this week warned that transmissions are getting harder to track. The virus is spreading quickly and unpredictably as people increase their activities and practise less social distancing. Health officials fear a massive wave of infection if the chains of transmission cannot be broken by contact tracing and isolation.
