Seoul, Ramadan 2, 1436, Jun 19, 2015, SPA -- The head of the World Health Organization has praised South Korean officials and health workers, saying their efforts to contain a deadly MERS virus outbreak have put the country on good footing and lowered the public risk. Margaret Chan said it's a good sign the disease has so far been confined to a handful of hospitals and isn't spreading in the wider community, AP reported. "All the new information is reassuring, but that reassurance must be qualified," Chan said Thursday at a news conference in Seoul. She cautioned that much about MERS is unknown and there's still a need to strengthen monitoring and quarantine efforts. --SPA 13:31 LOCAL TIME 10:31 GMT www.spa.gov.sa/w
