Via the KSA MOH corona page: Health: recording cases of one virus (Corona) new in the Riyadh region. A Google translation:
In the context of the work of epidemiological investigation and ongoing follow-up carried out by the Ministry of Health for the virus, "Corona" that causes Acquired Middle East respiratory MERS CoV, Ministry announces the registration of the case of HIV infection to the citizen in Riyadh at the age of 86 years, Mkhalt of confirmed cases and has no symptoms.
I believe "Mkhalt" means "contact." This person could be the parent of either of the two MERS cases reported yesterday: the 55-year-old who died, or the 51-year-old in intensive care. Or simply another patient in the same hospital.
