Question

    Snakebites affect between 1.2 million and 5 million people each year around the world. Adults, children and pets around the world experience them. They can result in swelling, bleeding or even death. Any snakebite can be dangerous if infection sets in. Some types of snake venom make the bite area swollen or painful. Others cause bleeding or damage the heart’s nerves. Here are some especially dangerous snakes:

    The largest of all poisonous snakes, king cobras can reach 5.5 meters in length. Each king cobra bite contains enough poison to kill an elephant – or 20 people. But these massive snakes usually avoid people. They live throughout India, southern China and Southeast Asia.

    A bite from Australia’s inland taipan, the world’s most poisonous snake, releases enough venom to kill 100 men. The good news is that people rarely come in contact with this snake, and a treatment for its venom exists.

    Russell’s viper lives throughout Asia, including India, southern China, and on the island of Taiwan. It prefers grassy fields but can be found in forests and cities. It bites more people and causes more deaths than any other poisonous snake.

    Though short, the common Indian krait packs a powerful punch in its bite. Most often, it strikes people at night while they are sleeping. Since the bite causes little pain, victims are often not sure that they have been bitten until they begin to experience stomach cramps. Without treatment, symptoms will worsen quickly and can lead to death.

    The black mamba, a native of Africa, is actually olive or grey in color. Only the inside of its mouth is black. When black mambas feel threatened by a human, they make a loud hissing sound to warn the person away. If the warning is ignored, the snake will attack the person repeatedly. And they can attack quickly, moving over the ground at speeds of up to 20 kilometers per hour.

    If a snake bites you, try to get back so it doesn’t bite again. And try to identify it if you can do so safely. Remove any jewelry that could constrict the bitten area. And avoid moving the affected limb (四肢) to slow the venom’s spread. Most importantly to get antivenin, a medicine that will stop the venom’s effects. Even the most dangerous bites can be cured with quick medical treatment.  (403 words)
