Since the previous update on 05 May 2025, and as of 12 May 2025, nine new MERS-CoV cases—including two deaths—have been reported by health authorities in Saudi Arabia, bringing the total number of cases this year to ten.
Seven of the recent cases were part of the same cluster in Riyadh, including one patient with no history of contact with camels and six healthcare workers who acquired nosocomial infections from that patient in early May.
The risk of sustained human-to-human transmission in Europe remains very low. However, the current MERS-CoV situation is concerning, as this rise in cases comes just two weeks ahead of the Mecca pilgrimage—a period typically associated with high international travel.
