South Korea fights to contain MERS outbreak, considers tough measures
[SEOUL] South Korea struggled to contain an outbreak of Middle East Respiratory Syndrome (MERS) on Monday as health authorities announced three more cases, bringing the number of infections to 18 in just over 10 days.
Authorities are considering a ban on overseas travel for the nearly 700 people isolated for possible infection after a 44-year-old man broke a voluntary house quarantine last week and flew to Hong Kong and then travelled to mainland China.
The man subsequently tested positive for MERS, China's first confirmed case, setting off alarm bells as health officials traced his footsteps and tested dozens of people who had been in close contact with him.
South Korea's Health Ministry confirmed three more cases on Monday, but declined to identify the location of any of the cases.
All 18 cases have been linked to a 68-year-old man - who returned from Bahrain via Qatar on May 20 - who were either patients or visitors to the hospital where he was being treated.
Later, a 58-year-old woman who had contact with the first patient but was not tested, died of respiratory failure, a health ministry official said, adding that clinical tests were being conducted to verify her cause of death.
First identified in humans in 2012, MERS is caused by a coronavirus from the same family as the one that triggered China's deadly 2003 outbreak of Severe Acute Respiratory Syndrome (SARS). There is no cure or vaccine.
The World Health Organization (WHO) put the total number of cases globally at 1,150 with at least 427 related deaths.
It said last week there had been no sustained human-to-human spread and that it was not recommending screening of passengers or that travel or trade restrictions be imposed on South Korea.
In South Korea, one elderly patient who had a history of kidney ailment was in a serious condition, with weak vital signs requiring him to be on cardiac and respiratory support, the head of the Korean Society of Infectious Diseases, Kim Woo-joo, told a briefing.
"I've been asking myself whether there may be a genetic factor, if anything makes (Koreans) more vulnerable, but so far there's no evidence," said Mr Kim, who is advising the Health Ministry on the outbreak.
The European Center for Disease Prevention and Control put South Korea's 18 cases the fourth highest number of confirmed cases, after Saudi Arabia, United Arab Emirates and Jordan.
Public health authorities faced more criticism on Monday for failing to contain the spread of the virus after the initial case whose symptoms were first overlooked.
"We must find the reason for the high rate of transmission unlike in the cases of other countries," President Park Geun-hye told a meeting on Monday.
