Scientists concerned at H7N9 bird flu outbreak that has killed 24 people


SUMMARY:


There are a virus killing a fifth of those infected in China and the World Health Organisation considers it a serious threat.
A Chinese scientists are worry about flu, called H7N9, is transmitted from chickens to humans, but the worst is that the virus will mutate. If the mutated virus can spread worldwide and the virus can be lethal. And if bird flu mutate, it will be transmitted swift from human to human. The 20% of patients are recovering, the other 20% have died and 60% even still sick.
It is believed that the source of this virus is the combination of four different viruses of ducks. But the flu doesn’t cause disease in ducks and you can’t know what they are sick. Scientists are looking for some solution or flu vaccine.

OPINION:

I believe that we will have learnt to the past and we have look all events of illnesses, how the black plague, Spanish flu, Typhus, malaria and others. For that doesn’t happen so must act fast. These epidemics caused the decline of society. In the century XX, this event will be worse because there are many media transports, and it doing that spreads faster and distant sites. I hope the flu won't spread by other countries, and they will wipe out the bird flu.
