Q&A: The new coronavirus Q&A: MERS - the new coronavirus
(about 1 month later)
A new respiratory illness similar to the Sars virus that spread globally in 2003 and killed hundreds of people has been identified.A new respiratory illness similar to the Sars virus that spread globally in 2003 and killed hundreds of people has been identified.
The World Health Organization says it appears "increasingly" likely that novel coronavirus can be passed between people in close contact. It has been named the MERS (Middle East respiratory-syndrome) coronavirus.
What is this new coronavirus and should we be concerned? The World Health Organization (WHO) says MERS appears "increasingly" likely that novel coronavirus can be passed between people in close contact.

The new virus is not Sars.
There have been 34 confirmed cases of the infection around the world and 18 deaths. As of July 5th, there have been 77 confirmed cases of the infection around the world and 41 deaths. The first fatality was recorded in June 2012 in Saudi Arabia.
Cases have been detected in Saudi Arabia and Jordan and have spread to Germany, the UK and France. Most have come from an unidentified animal source - but there have been cases where the virus has spread between two people.
Cases have been confirmed in Jordan, Qatar, Saudi Arabia, the United Arab Emirates, France, Germany, Italy, Tunisia and the UK.

It causes pneumonia and, sometimes, kidney failure. Most of the people who have been infected so far have been older men, often with other medical conditions. Experts say they are not sure why we are seeing this pattern and if it will change over time.It causes pneumonia and, sometimes, kidney failure.

The fact that close contacts appear to have been infected suggests that the virus does have limited ability to pass from person to person.The fact that close contacts appear to have been infected suggests that the virus does have limited ability to pass from person to person.

Coronaviruses are fairly fragile. Outside of the body they can only survive for a day and are easily destroyed by usual detergents and cleaning agents.Coronaviruses are fairly fragile.

Public health experts in the UK have stressed that the risk to general population remains very low.Public health experts in the UK have stressed that the risk to general population remains very low.
The greatest global concern, however, is about the potential for this new virus to spread far and wide. So far, person-to-person transmission has remained limited to some small clusters. There is no evidence yet that the virus has the capacity to become pandemic.The greatest global concern, however, is about the potential for this new virus to spread far and wide.

Can it be treated?Can it be treated?
Doctors do not yet know what the best treatment is, but people with severe symptoms will need intensive medical care to help them breath.

What can I do to protect myself?What can I do to protect myself?
It's not known exactly how people catch this virus. However, some general measures may help prevent its spread - avoid close contact, when possible, with anyone who shows symptoms of illness (coughing and sneezing) and maintain good hand hygiene.It's not known exactly how people catch this virus.

Where did it come from?Where did it come from?
Experts do not yet know where the virus originated from. It may have been the result of a new mutation of an existing virus. Or it may be an infection that has been circulating in animals and has now made the jump to humans.Experts do not yet know where the virus originated from.

Is there any travel advice?Is there any travel advice?
At the moment the World Health Organization says there is no reason to impose any travel restrictions. Travel advice will be kept under review if additional cases occur or when the patterns of transmission become clearer. At the moment the WHO says there is no reason to impose any travel restrictions.

Sars is thought to have infected more than 8,000 people, mainly in China and South East Asia, in an outbreak that started in early 2003. The illness spread to more than two dozen countries in North America, South America, Europe, and Asia before the global outbreak was contained.Sars is thought to have infected more than 8,000 people, mainly in China and South East Asia, in an outbreak that started in early 2003.
