UK cases of swine flu confirmed

Two people in Scotland have tested positive for the swine flu disease after travelling home from Mexico.

The couple are recovering in hospital after finding out they'd caught the virus while on honeymoon in Cancun.

Swine flu usually affects pigs, but a new version of it is spreading from person to person by coughs and sneezes.

In Mexico, more than 150 people are now thought to have died from the virus. It's also infected people in America, Canada, New Zealand, Israel and Spain.

But experts say there's no need to panic as governments and doctors around the world are doing all they can to stop the virus spreading even further.

At the moment, it's only causing mild illness to people outside Mexico.

Advice if you're worried about swine flu

People who've been to Mexico - where swine flu was first found - are being tested for the virus if they feel unwell and others are being warned not to travel to the country unless they have to.

Unusual in UK

Lots of the symptoms of swine flu are like ordinary flu - a fever, feeling tired, coughing and having a sore throat.

But even if you have all these symptoms, it's REALLY UNLIKELY you have swine flu as it's still very unusual in the UK.

Swine flu is a disease found in pigs

Human cases usually occur in those who have contact with pigs

It's rare to be spread person-to-person and such cases are studied closely

Doctors who have studied the virus say it's like other types of flu, but has bits mixed into it from the flu bugs that pigs and birds can catch.

Medicine that's used to treat ordinary flu has been helping people with swine flu to get better and scientists are working on a new drug that could stop people catching the bug in the future.

In the meantime, officials say the UK has been planning what to do if there's a flu outbreak for some time so they have loads of flu medicines ready.

It's important to remember that you CAN'T catch the bug from eating meat from pigs, as long as it is cooked properly.

Swine is another word for pig. It's unusual for people to catch swine flu and those that do get it normally do so from being around pigs.

This version is worrying people because it's now being passed from person to person without them being near pigs.
