Saudi Arabia has recorded 147 MERS cases , of which 61 have now proven fatal, since the virus first emerged in 2012.
According to the World Health Organization (WHO),  182 cases of MERS infection  are reported worldwide. The organization added that it has also recorded 79 deaths from the illness for which there is no vaccine.
