People keep talkin about SWINE FLU, at the first time I watch d news about it, i totally shocked, Swine got a FLU too? LOL
but after watching, hearing, searching information about this kinda flu,
i totally understand that its not a joke
here, i got an Information from BBC news
(bcoz i now about swine flu at d first time in there xD)
Q&A Swine Flu
Cases of swine flu, which has killed at least two people, have been confirmed around the world. With experts scrambling to develop a vaccine, there is concern at the potential for a pandemic affecting millions of people.
What is swine flu?
Swine flu is a respiratory disease, caused by influenza type A which infects pigs.
There are many types, and the infection is constantly changing.
Until now it has not normally infected humans, but the latest form clearly does, and can be spread from person to person - probably through coughing and sneezing.
What is new about this type of swine flu?
The World Health Organization has confirmed that at least some of the human cases are a never-before-seen version of the H1N1 strain of influenza type A.
How dangerous is it?
Symptoms of swine flu in humans appear to be similar to those produced by standard, seasonal flu.
These include fever, cough, sore throat, body aches, chills and fatigue.
It is worth remembering that seasonal flu often poses a serious threat to public health: each year it kills 250,000 - 500,000 around the world.
So far, most cases of swine flu around the world appear to be mild, albeit with diarrhoea more common than it is with seasonal flu.
But lives have been lost in Mexico, and two deaths of people with swine flu have been confirmed in the US.
How worried should people be?
When any new strain of flu emerges that acquires the ability to pass from person to person, it is monitored very closely in case it has the potential to spark a global epidemic, or pandemic.
Can the virus be contained?
The virus appears already to have started to spread around the world, and most experts believe that, in the era of readily available air travel, containment will be extremely difficult.
The World Health Organization says that restricting flights will have little effect. It argues that screening of passengers is also unlikely to have much impact, as symptoms may not be apparent in many infected people.
Can it be treated?
The US authorities say that two drugs commonly used to treat flu, Tamiflu and Relenza, seem to be effective at treating cases that have occurred there so far. However, the drugs must be administered at an early stage to be effective.
Use of these drugs may also make it less likely that infected people will pass the virus on to others.
The UK Government already has a stockpile of Tamiflu, ordered as a precaution against a pandemic.
However, there is concern that if too many people start taking anti-virals as a precaution, it could raise the risk of the virus developing resistance, reducing the drugs' effectiveness.
What about a vaccine?
It is unclear how effective currently available flu vaccines would be at offering protection against the new strain, as it is genetically distinct from other flu strains.
A new bespoke vaccine is being worked on by scientists in the UK and the US, but it may take months to perfect it, and manufacture enough supplies to meet what could be huge demand.
A vaccine was used to protect humans from a version of swine flu in the US in 1976.
However, it caused serious side effects, including an estimated 500 cases of Guillain-Barré syndrome. There were more deaths from the vaccine than the outbreak.
What should I do to stay safe?
Anyone with flu-like symptoms who might have been in contact with the swine virus - such as those living or travelling in the areas of Mexico that have been affected - should seek medical advice.
But patients are being asked not to go into GP surgeries in order to minimise the risk of spreading the disease to others. Instead, they should stay at home and call their healthcare provider for advice.
Countries around the world have taken varying measures but are mostly stepping up monitoring and issuing advice about travel to Mexico.
In the UK, the Foreign Office is advising against all but essential travel to Mexico.
What measures can I take to prevent infection?
Avoid close contact with people who appear unwell and who have fever and cough.
General infection control practices and good hygiene can help to reduce transmission of all viruses, including the human swine influenza. This includes covering your nose and mouth when coughing or sneezing, using a tissue when possible and disposing of it promptly.
It is also important to wash your hands frequently with soap and water to reduce the spread of the virus from your hands to face or to other people and cleaning hard surfaces like door handles frequently using a normal cleaning product.
If caring for someone with a flu-like illness, a mask may be worn to cover the nose and mouth to reduce the risk of transmission. The UK is looking at increasing its stockpile of masks for healthcare workers for this reason.
In Mexico masks have been handed out to the general public, but experts are sceptical about how useful this is.
May it take some time for a pandemic to strike?
Possibly. The flu virus tends to thrive in cooler conditions, and to struggle in warmer weather.
The initial cases have developed right at the tail end of the winter flu season in the northern hemisphere, so it is possible that the number of infections may only begin to accelerate once the weather turns colder in the autumn.
However, the southern hemisphere is about to enter its winter season and it is possible that the virus will take hold there first.
Is it safe to eat pig meat? (for you christians)
Yes. There is no evidence that swine flu can be transmitted through eating meat from infected animals.
However, it is essential to cook meat properly. A temperature of 70C (158F) would be sure to kill the virus.
Experts are also stressing that this is now a disease which is being passed between people.
The World Organisation for Animal Health said culling pigs, as Egypt has proposed, was therefore "inappropriate" as a measure to stop swine flu spreading.
It added there was no evidence of infection in pigs, nor of humans acquiring infection directly from pigs.

SWINE FLU - THE BASICS
-Symptoms usually similar to seasonal flu - but deaths recorded in Mexico
-It is a new version of the H1N1 strain which caused the 1918 flu pandemic
-Too early to say whether it will lead to a pandemic
-Current treatments do work, but there is no vaccine
-Good personal hygiene, such as washing hands, covering nose when sneezing advised
