September 20, 2013 Since emerging last year in the Middle East, a mysterious virus has infected at least 132 people and killed 58. But it's still unknown how people get infected. A genetic analysis now suggests that animals may have repeatedly infected people with the deadly virus.
September 8, 2013 Scientists offer a glimmer of hope that a treatment for humans with the deadly disease might be on the horizon. Two drugs commonly used to treat other viral infections reduced the symptoms of the Middle East respiratory syndrome in a small number of monkeys.
August 21, 2013 Just a fragment of genes in bat guano was enough for researchers trying to find out how a deadly new virus spreads. It's the first time the Middle East respiratory syndrome virus has been found in an animal, and offers strong evidence that bats carry the virus.
August 9, 2013 Scientists find the a tantalizing clue about where people may be catching the Middle East respiratory syndrome. Camels on the Arabian Peninsula and Canary Islands show signs that they've been infected with the virus or a close relative.
June 20, 2013 Middle East Respiratory Syndrome emerged a year ago in Saudi Arabia, although the world didn't find out about it until September, when researchers said it was caused by a previously unknown virus that's in the same family as SARS.
June 3, 2013 The World Health Organization says lab tests have confirmed the infections in a 2-year-old girl and a 42-year-old woman with the Middle East Respiratory Syndrome Coronavirus. Both patients are close contacts of someone who traveled to Jordan recently.
May 29, 2013 All told, the fatality rate for confirmed infections with the virus has been more than 50 percent. But the true fatality rate won't be clear until the fuller extent of cases, some probably much milder, becomes known.
May 13, 2013 SARS burst on the scene in 2003 after one man infected travelers staying on the same floor of a Hong Kong hotel. Now that a new virus with similarities to SARS has spread from person to person, public health officials are urging hospitals to be on guard.
May 2, 2013 A new virus that causes severe pneumonia and sometimes kidney failure has infected more people. Since the virus first appeared in March 2012, it has infected 24 people, including 17 deaths.
February 27, 2013 So far, there have been only a few cases of illness tied to a new kind of coronavirus. But the urgency to learn more about the virus was heightened recently when the first instances of person-to-person infection were seen.
February 19, 2013 A new virus, which causes severe pneumonia, has killed a British man with a suppressed immune system. This is the sixth death from the coronavirus and the first outside the Middle East, where it emerged last year. Officials say the risk to the general population is low.
February 13, 2013 Until now, a new SARS-like virus showed little signs of being contagious. Only 10 cases have been reported, and all appeared to originate in the Middle East. Health officials now say a British resident likely caught the virus from a family member in the U.K., indicating that the virus can spread between people.
November 30, 2012 The latest cases represent the oldest known so far. They push the SARS-like virus's timeline back three months from the first reported case involving a 60-year-old man who died in Jedda, Saudi Arabia, last June.
November 28, 2012 A few months ago health workers discovered a new variety of coronavirus that killed one man and hospitalized another. Now the virus has infected four more people in the Middle East. How they got sick is a question scientists would like to answer.
