As of 12 June 2015, 3,680 contacts have been identified (3,453 are under home monitoring and 227 under facility monitoring) and 1,249 contacts have been released.The large number of contacts currently being monitored makes the detection of at least some further cases inevitable.

In the US, the Centers for Disease Control and Prevention (CDC) issued a health advisory on June 11 to provide updated guidance to state health departments and healthcare providers in the evaluation of patients for MERS-CoV infection, which have been revised in light of the current situation in the Republic of Korea.
