A health ministry statement said the new cases had been reported in the capital Riyadh, the coastal city of Jeddah and the "holy capital" Mecca in the past 24 hours. Authorities had also registered five more deaths due to the virus, it said, Voice of Russia reported.
The jump in cases is of particular concern because Saudi Arabia will host pilgrims from around the world in July during the Muslim month of Ramadan, as well as in early October when millions of worshippers perform the annual Haj.
In total, 92 people have died of MERS in Saudi Arabia, the ministry said on its website.
Saudi Arabia has witnessed a jump in the rate of infection in recent weeks, with many of the new cases recorded in Jeddah, the kingdom’s second-largest city. A large proportion of the people infected are healthcare workers.
MERS emerged in the Middle East in 2012 and is from the same family as the SARS virus, which killed around 800 people worldwide after first appearing in China in 2002. MERS can cause coughing, fever and pneumonia.
