Swine Flu
What is swine flu?
Flu occurs in many animal species as well as in humans, such as horses, pigs and birds. Flu strains normally circulate only among members of their habitual host species. Occasionally a new strain emerges that is capable of making the leap from one species to another. This has now happened with swine flu: the new strain appears to have "hybrid" characteristics of pig, bird and human flu, with the added ability of now being able to circulate easily between humans.
This new "Swine flu" or H1N1 virus was first detected in people in April 2009 in the United States and Mexico. This virus spreads from person-to-person, probably in much the same way that regular seasonal influenza viruses spread.
This virus was originally referred to as "swine flu" because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America.
How is it spread?
It spreads in exactly the same way as "normal" seasonal flu - by inhalation and via contaminated objects (for example, by touching them and then bringing your hand to your mouth).
How serious is it?
We don't fully know. The initial cases in Mexico appeared to have a much higher fatality rate than ordinary seasonal flu, with young adults more seriously affected than the usual risk groups for seasonal flu, such as the elderly. The cases that have spread beyond Mexico so far seem rather milder, but it is still too soon for a true picture of things to be clear. So far 29 people have died from swine flu in the UK (17th July 2009).
What precautions can you take?
The good news is that antiviral drugs are known to be effective and can be used both for treatment and for prevention in appropriate circumstances. These are not vaccines, but come as capsules (Tamiflu) or an inhaler (Relenza). There is no reason for people to take these at the moment, unless they actually have symptoms. First-line precautions include frequent hand washing and minimising contact with people who are unwell.
Is it worth getting a seasonal flu vaccination?
The flu vaccination will not offer any protection against swine flu.
Is there a vaccine for swine flu?
A vaccine for swine flu is currently being developed. It should be available from September onwards.
What are the symptoms of swine flu?
The same as normal flu symptoms i.e. Fever, weakness, muscle pains and a cough.
What should you do if you have any symptoms?
If you are unwell with symptoms of flu, report them to your GP or to NHS Direct (Tel: 0845 46 47), and stay at home.
