South Korea announces official end to MERS outbreak
South Korea announced on Wednesday the official end to a deadly outbreak of Middle East Respiratory Syndrome (MERS) that killed 36 people and sparked widespread panic in Asia's fourth-largest economy. World Health Organization standards call for a four-week waiting period after the last MERS patient fully recovers before an outbreak can definitively be said to be over. The virus infected 186 people, with nearly 17,000 people confined to their homes and thousands of schools temporarily closing at the peak of the largest MERS outbreak outside Saudi Arabia, where it first appeared in 2012.
