Mysterious New MERS Virus Spreads Easily, Deadlier Than SARS

Mysterious new MERS virus spreads easily, deadlier than SARS

A mysterious new respiratory virus that originated in the Middle East spreads easily between people and appears more deadly than SARS, doctors reported Wednesday after investigating the biggest outbreak in Saudi Arabia.
More than 60 cases of what is now called MERS, including 38 deaths, have been recorded by the World Health Organization in the past year, mostly in Saudi Arabia. So far, illnesses haven’t spread as quickly as SARS did in 2003, ultimately triggering a global outbreak that killed about 800 people.
An international team of doctors who investigated nearly two dozen cases in eastern Saudi Arabia found the new coronavirus has some striking similarities to SARS. Unlike SARS, though, scientists remain baffled as to the source of MERS.
In a worrying finding, the team said MERS (Middle East respiratory syndrome) not only spreads easily between people, but within hospitals. That was also the case with SARS, a distant relative of the new virus.
“To me, this felt a lot like SARS did,” said Dr. Trish Perl, a senior hospital epidemiologist at Johns Hopkins Medicine, who was part of the team. Their report was published online Wednesday in the New England Journal of Medicine.
Perl said they couldn’t nail down how it was spread in every case — through droplets from sneezing or coughing, or a more indirect route. Some of the hospital patients weren’t close to the infected person, but somehow picked up the virus.
“In the right circumstances, the spread could be explosive,” said Perl, while emphasizing that the team only had a snapshot of one MERS cluster in Saudi Arabia.
