What causes MERS?
MERS is caused by a virus called Middle East respiratory syndrome coronavirus (MERS‐CoV). The virus was first found in Saudi Arabia in 2012.
MERS is a zoonotic disease, which means it spreads from animals to people.
MERS can be spread to humans from infected dromedary camels. It is spread by close contact with:
- camels
- camel products (such as camel milk or camel meat)
- infected people
Exactly how MERS spreads from camels to people is not well understood.
No cases of MERS have been found in Australia, and the virus has not been detected in Australian camels.
The virus doesn't seem to spread easily from person to person. The way MERS spreads between people isn't well understood.

If you become unwell while travelling in the Middle East, get medical help. Go to a local doctor or hospital emergency department.

How is MERS treated?

MERS seems to cause more severe disease in:
- older people
- people with a weakened immune system
- people with a chronic disease
If you fit one or more of these criteria, you should avoid all contact with camels in the Middle East.
Can MERS be prevented?
There is currently no vaccination to protect against MERS.
If you go to the Middle East, here's how you can reduce your chance of catching MERS:
- Avoid close contact with camels.
- Avoid close contact with people who are sick.
- Wash your hands often.
- before eating
- after touching animals
Use hand sanitiser if soap and water is not available.
You should also avoid:
- drinking raw camel milk or urine (wee)
- eating undercooked camel meat
Avoid all contact with camels if you have an existing health condition that makes you vulnerable to breathing problems.
Make sure all your vaccinations are up to date before you travel. Talk to your doctor and decide whether the risk of travelling to the Middle East is appropriate for you.
