Latest WHO MERS-CoV global summary and assessment of risk

July 2017 -- Between 2012 and 21 July 2017, 2040 laboratory-confirmed cases of Middle East respiratory syndrome-coronavirus (MERS-CoV) infection were reported to WHO, 82% of whom were reported by the Kingdom of Saudi Arabia. In total, cases have been reported from 27 countries in the Middle East, North Africa, Europe, the United States of America, and Asia. Thus far, no sustained human-to-human transmission has occurred anywhere in the world, however limited non-sustained human-to-human transmission in health-care facilities remains a prominent feature of this virus. WHO continues to work with health authorities in the affected countries.


WHO publishes MERS-CoV vaccine product profile

New standards for vaccines for MERS-CoV – which has so far killed at least 693 people – have been set by WHO and partners. The “WHO Target Product Profiles for MERS-CoV Vaccines” describes minimum acceptable standards for three vaccines currently under development: one vaccine intended to prevent transmission of this virus from dromedary camels to people; and two vaccines for use in outbreaks of this deadly disease and for longer-term protection of people at high risk.
