The numbers rise again and "foreign specialists" have been hired (?perhaps invited) to help the Kingdom contain the spread of MERS-CoV. While human-to-human transmission is very likely occurring, sustained transmission that is, infection going beyond the immediate close contact, to their contacts and so on, is not. See the figure - circles represent a person; yellow represents spread beyond immediate and close contacts.MERS-CoV transmission seems to be limited to close contact and perhaps long exposure.
