Thanks to Greg Folkers for sending the link to this report in Travel Medicine and Infectious Disease: Travel implications of emerging coronaviruses: SARS and MERS-CoV. the corresponding author is Dr. Ziad A. Memish, and this is, to my knowledge, his first scientific publication since his departure from the KSA MOH. The abstract:
The emergence of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and of the Middle East Syndrome Cornavirus (MERS-CoV) caused widespread fear and concern for their potential threat to global health security. There are similarities and differences in the epidemiology and clinical features between these two diseases. The origin of SARS-COV and MERS-CoV is thought to be an animal source with subsequent transmission to humans. The identification of both the intermediate host and the exact route of transmission of MERS-CoV is crucial for the subsequent prevention of the introduction of the virus into the human population. So far MERS-CoV had resulted in a limited travel-associated human cases with no major events related to the Hajj.
I agree: It's not a very good abstract. If you can access the full report, you'll find it's more detailed, though it doesn't tell us much that's really new. The Great Saudi MERS Study remains to be written.
