World Health Organization Director-General Tedros Adhanom Ghebreyesus said on Friday the "window of opportunity is narrowing" to contain the coronavirus outbreak as more cases are reported outside of China. Iran has acknowledged 18 coronavirus cases across three cities as well as four deaths, while the number of cases in South Korea surpassed 200. The mayor of the South Korean city of Daegu urged the city's 2.5 million people to stay home after a concentration of coronavirus cases broke out at a church where a woman continued attending services after developing symptoms. In Italy, the number of cases has jumped from three to 17, and thirty-four cases have been confirmed in the United States.
