From bats to our bodies
保护野生动物，就是保护人类自己
The novel coronavirus pneumonia (NCP, 新型冠状病毒肺炎) outbreak in China was caused by a new coronavirus that we have never seen before. It was first found in the Huanan Seafood Market in Wuhan, where a variety of (各种) wild animals were on sale. People who sold and bought animals illegally (非法) were the first to be infected (感染).
Scientists have found that the virus likely came from bats and was then spread to humans from pangolins (穿山甲). According to Live Science, bats can carry and spread more than 60 viruses that can infect humans. They include the world’s deadliest (最致命的) viruses, such as Ebola and SARS. Other wild animals like snakes and hedgehogs (刺猬) are also hosts of many viruses.
There have been calls for people to stop eating wild animals. However, the danger is not just in eating them, but also in touching them. People can get infected if they come into contact (接触) with the body fluids (体液) of wild animals. People who hunt, kill, sell or eat these animals run the risk (风险) of becoming infected.
Keeping wild animals as pets or selling parts of their bodies as animal products (商品) also create risks for humans. It is highly possible to come into contact with the body fluids of wild animals in this way.
“Trade and consumption (消费) of wild animals of all kinds should be banned (禁止),” Zeng Guang, chief epidemiologist (流行病学家) at the Chinese Center for Disease Control and Prevention, told China Daily. “Otherwise people will suffer.”
Why are bats the source of so many viruses?
1
Bats tend to live in dark and wet places, where there are all kinds of viruses.
2
Bats always live in groups. Therefore, the viruses can have larger “playgrounds” to evolve (进化) and become more powerful variants (变体).
3
Bats are mammals (哺乳动物), just like humans. Our similar genes (基因) make it easier for us to become infected with the same viruses.
4
When bats fly, their body temperature can reach as high as 40 C. This high temperature can kill weak viruses, but stronger ones will survive (存活) and continue to evolve.
5
Bats have special immune (免疫的) systems that allow them to live with viruses without getting sick.
6
Since they can fly, bats can spread viruses farther and more easily than other animals.
Note
Although wild animals carry many diseases, it doesn’t mean that we should regard them as evil. Each species has a role in the ecosystem (生态系统) and all of them are important for keeping a good ecological balance. The lesson we should learn from virus outbreaks is to respect and protect animals and to live in harmony with them, instead of hunting, killing, or eating them.
