Saudi Arabia has detected six new cases of the deadly Middle East Respiratory Syndrome (MERS) in 24 hours, the biggest daily jump for months with officials blaming lax hospital procedures.

The recent surge in cases, now numbering 32 since the start of October, has been focused in Riyadh and the western city of Taif, but it remains far less extensive than an outbreak in April and May that infected hundreds.

Two of the new cases announced by the health ministry were in medical personnel, adding to concerns about the standard of infection control procedures in medical facilities. Three different Taif hospitals have been affected.
