Last year ago people around the world just known the new type of flu , we known it as swine flu.
When I have read about swine flu I was amazed because I thought that swine flu is the new flu but it doesn't a new flu, we have this virus for long time ago but it is infected from pigs to pigs but nowadays it is can infected from pigs to human. And it was very fast when this virus can infecting people in Mexico to around the world even in Thailand. Thai people become awakened since we know it is dangerous. We also put mask on, wash our hands, and do exercise.
