Saudi Arabia has announced that another 13 people have died from the MERS coronavirus in the past day, as the World Health Organisation prepares for an emergency meeting over concerns about the spread of the disease.
The Middle East Respiratory System coronavirus has now killed 139 people and infected 480 others in the kingdom since it first appeared in 2012.
The increase in the number of cases in different countries raises a number of questions.
