A report on a 3-case MERS cluster last year highlights diagnostic difficulties.
Saudi Arabia has reported seven more MERS-CoV infections since Jun 6, lifting the country's count to 700 cases, including 287 deaths.
The Saudi Ministry of Health (MOH) reported 4 MERS-CoV (Middle East respiratory syndrome coronavirus) cases on Jun 6, 1 on Jun 7, and 2 today. (The Jun 6 cases were not reported here previously because the ministry's Web site was down much of that day.)
Several factors contributed, the WHO says, while experts call for case-control studies.
Saudi officials plan to test all domestic camels for MERS-CoV and note two more human cases.
Genetic sequencing has shown the MERS virus in a man and his sick camels to be identical.
Questions continue over possibly scores of previously unreported cases and deaths.
Saudi totals now stand at 689 MERS cases and 283 deaths.
As MERS arrives in Algeria, Saudi Arabia reports 6 more cases and the sacking of Ziad Memish, MD.
Just 1 Saudi case today, an Iranian patient has died, and the US plans serology tests.
Also today, scientists filled in more details about the first two Dutch MERS cases.
