What is the swine flu?

Swine flu (also referred to as novel H1N1 virus) is a new virus that hasn't spread before among humans. The virus was first detected in people in March 2009.

It's a brand new mutation that's never been seen before. That's why it's not just hitting people in the highest risk groups - those over 65 and younger than two.

Flu is not usually a huge worry among the vast majority of healthy people because over the course of our lives, we are exposed to several flu strains. We develop some immunities. When we get the flu, we'll normally just feel really awful for a week or two. But when you have no immunities at all to a new strain, normally healthy people face as much of a risk as higher risk groups.

How does swine flu kill?

Swine flu - just like any other flu - is a respiratory infection. It exploits a weakened immune system to attack major organs - especially your lungs. When it gets into your lungs, it can lead to pneumonia, which can kill you. The flu can also cause secondary infections in your body - any of which can lead to failure of vital organs and death.

Can people catch swine flu from eating pork?

No. Swine flu viruses are not transmitted by food. You cannot get swine flu from eating pork or pork products. You won't get swine flu from handling uncooked pork either. You can get sick from putting uncooked or undercooked pork in your mouth, but you won't get swine flu.

On May 7, 2009, the World Health Organization once again said that it is generally safe to eat pork. The world health body said existing sanitary and animal health checks were sufficient to safeguard the food supply against the swine flu virus. The statement came a day after an official said it was possible the virus could survive freezing if a slaughtered animal was sick. However, it is illegal to slaughter a sick or dead animal.

If you eat meat from an animal that was sick or had died before it was slaughtered you are taking major risks, the least of which is swine flu.

It's also impossible to catch swine flu from eating fruits and vegetables imported from Mexico or any other country that has recorded cases of swine flu. Swine flu - like all influenza viruses - is not a food-borne illness.

What are the symptoms of swine flu in humans?

The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza and include fever, lethargy, lack of appetite and coughing. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea.

How does swine flu spread?

Influenza viruses can be directly transmitted from pigs to people and from people to pigs. Human infection with swine flu viruses are most likely to occur when people are in close proximity to infected pigs, such as in pig barns and livestock exhibits at fairs.

Human-to-human transmission of swine flu can also occur. This is thought to occur in the same way as seasonal flu occurs in people, which is mainly person-to-person transmission through coughing or sneezing of people infected with the flu virus. People may become infected by touching something with flu viruses on it and then touching their mouth or nose.
