Amid fears of a new pandemic more deadly than Sars, 80 officials and doctors, including two from Britain, gathered in Cairo yesterday to examine ways of tackling Middle East Respiratory Syndrome, dubbed MERS.
The coronavirus is casting a shadow over the annual Muslim pilgrimages to Saudi Arabia, where four new deaths were announced on Monday.
The three-day meeting called by the World Health Organisation will look at developing guidelines for Ramadan. In October, more than two million people are expected to attend the Hajj pilgrimage to Mecca.
