Here's a report from one of them, afifnp.com: Mobilization of teaching chaste after the death of a teacher b «Corona» and wounding Director. "Chaste" seems to be a translation artifact from the name of the province. A Google translation:
Live middle school second for Boys "province chaste state of anxiety after the death of one of its teachers as a result of his symptoms disease Koruna awaiting the emergence of analyzes with lying director of the school on the white bed after their suspected cases of cholera.
was Director of the Department of Education Bafeef "Saad Nfaiei" the day, accompanied by a medical team a visit to the school to make sure that there are no symptoms of the disease on the students or teachers were transferring a student to the hospital after noticing the temperature rise has as been awarded the director of the school vacation until his recovery.

The reference to "cholera" may also be an artifact. In any case, the city appears to be truly alarmed about the two cases (neither of which seems to have been confirmed as MERS).
