(CNN) — The Middle East Respiratory Syndrome Coronavirus, better known as MERS, may be an airborne virus, according to an observation paper published Tuesday in the journal mBio.

There have been 836 laboratory-confirmed cases of MERS infection since its first appearance in 2012, according to the latest numbers provided by the World Health Organization. At least 288 related deaths have officially been reported to the WHO.

Scientists are still trying to figure out how the deadly virus is transmitted.
