Bird Flu Crisis in Hong Kong
Do you know how many chickens do we consume every day? Three thousand, five thousand or more? We demand almost more than ten thousand chickens daily. What a big figure! We can see that chickens are very important to Chinese society. Chickens are always devoted to God and served in dinners to celebrate traditional festivals. Without chickens, it will cause inconvenience to Hong Kong people, especially during Lunar New Year. Unfortunately, Hong Kong people has just encountered this situation. Because of the outbreak of bird flu, all chickens had to be removed from Hong Kong. In this report, we would like to talk about the topic ¡¥Bird Flu Crisis In Hong Kong¡¦. We will give a brief introduction of the bird flu virus H5N1, analyse the short-term and long-term consequences of the flu in Hong Kong and see what Hong Kong have learned from this incident.

What is H5N1? H stands for hemagglutinin (HA), which is a viral protein. It will cause the red blood cells to stick together. And N is the viral protein too, which is called neuraminidase (NA). In an influenza virion, there are five hundred spikes sticking out from its lipid envelope in which 80% of the spikes are HA and 20% NA. HA helps the virion get into host cells and NA helps the offspring virions to get out. The two virions together are responsible for the viruses¡¦ability to cause the disease.

Short-term consequences of bird flu crisis
