Recent data from the CDC show that Summers could prove to be transmitted between humans. Even so, it seems that the disease can not spread very rapidly as SARS in 2003. Mers virus continues to get tighter supervision of the experts in case if virus is evolving into an increasingly dangerous threat.

"Knowledge of the virus is still very small compared with the likely to be a major threat. We do not know where this virus originated and hiding in nature. We do not understand how people could be infected," said Chan, a virus researcher Mers.

Chan explained that before the experts can clarify these questions, they still have to fight mers with bare hands. Until now Mers has infected more than 40 people and killing 22 people from around the world.

Three people have died from the new strain similar to SARS, the total number of people killed 27 people.

Mers-CoV virus has a close relationship with SARS, which killed about 800 people in the world in 2003. Dr Margaret Chan, head of WHO, deliver a speech on Monday (27/5) in Geneva.

"We have too little understanding of this virus when compared to the magnitude of the potential threat," said Chan at the WHO's annual meeting, as reported by the Daily Mail (29/5).

WHO also said earlier this month with 20 of the 40 confirmed cases end in death. Most of the infected people are confirmed to have traveled to Qatar, Saudi Arabia, Jordan or Pakistan. Also found a few cases in the UK and Germany.

To that end, the French authorities earlier this month started handing out flyers at the airport for the tourists who want to go to the Middle East to be more frequent hand washing and limiting contact with animals.
