People should be aware of poisonous snakes while spending time in nature, a Miaoli County-based doctor said, offering advice on the right response when a bite occurs.
There are six poisonous snake species that are common in Taiwan: the brown spotted pit viper, the Chinese bamboo pit viper, the cobra, the many-banded krait, the Chinese copperhead and the Siamese Russell’s viper, said Yan Chun-fang (顏群芳), a physician at Wei-Gong Memorial Hospital.
The snakes can be identified by their skin patterns, she said, adding that after a bite, it is crucial to identify the snake so that the right treatment can be initiated.

Most emergency rooms in Taiwan have charts to help people identify the snakes, she added.
People should consult a doctor even if no symptoms occur, she said, adding that non-venomous snakes might also bite.
If thrombosis, swelling or muscle weakness occurs after a bite, people might need to undergo an antivenom treatment, she said, adding that symptoms might vary, depending on the species of snake.
“A cobra bite will cause your eyes to droop, and cause difficulties speaking and swallowing, while a many-banded krait bite will cause a loss of muscle strength and breathing difficulty,” she said. “Bites from either of these species must be treated with an antivenom that targets neuromuscular paralysis.”
A Chinese copperhead bite causes a large reduction in blood platelets, which leads to bleeding, while a Siamese Russell’s viper’s bite causes rapid kidney failure, she said.
Bites from either of these snakes requires a specific antivenom, she said.
Antivenoms contain antibodies that neutralize a specific snake species’ venom, she said.
If bitten, it is important to remember characteristics of the snake’s appearance, she said.
Rings and other jewelry should be removed to prevent injury in the event of swelling, she said.
If possible, the part of the body with the bite site should be bandaged to slow the spread of the venom, she said.
“Remain calm and consult a doctor as soon as possible,” she said. “Do not cut open the injured area, as that could spread infection, and do not try to use your mouth to suck the venom out of the wound.”
Ice should not be applied to the bite site, as this could lead to necrosis of the skin near the affected area, she said, adding that coffee and alcohol should not be consumed, as that could accelerate the effect of the venom.
PEAK MONTHS: Data showed that on average 25 to 27 typhoons formed in the Pacific and South China seas annually, with about four forming per month in July and October One of three tropical depressions in the Pacific strengthened into a typhoon yesterday afternoon, while two others are expected to become typhoons by today, Central Weather Administration (CWA) forecaster Lee Ming-hsiang (李名翔) said yesterday. The outer circulation of Tropical Depression No. 20, now Typhoon Mitag, has brought light rain to Hualien, Taitung and areas in the south, Lee said, adding that as of 2pm yesterday, Mitag was moving west-northwest at 16kph, but is not expected to directly affect Taiwan. It was possible that Tropical Depression No. 21 would become a typhoon as soon as last night, he said. It was moving in a
A Taiwanese academic yesterday said that Chinese Ambassador to Denmark Wang Xuefeng (王雪峰) disrespected Denmark and Japan when he earlier this year allegedly asked Japan’s embassy to make Taiwan’s representatives leave an event in Copenhagen. The Danish-language Berlingske on Sunday reported the incident in an article with the headline “The emperor’s birthday ended in drama in Copenhagen: More conflict may be on the way between Denmark and China.” It said that on Feb. 26, the Japanese embassy in Denmark held an event for Japanese Emperor Naruhito’s birthday, with about 200 guests in attendance, including representatives from Taiwan. After addressing the Japanese hosts, Wang
One of two tropical depressions that formed offshore this morning could turn into a moderate typhoon by the weekend, the Central Weather Administration (CWA) said today. Tropical Depression No. 21 formed at 8am about 1,850km off the southeast coast, CWA forecaster Lee Meng-hsuan (李孟軒) said. It is expected to move in a northwesterly direction as it continues building momentum, possibly intensifying into Typhoon Mitag this weekend, she added. The radius of the storm is expected to reach almost 200km, she said. It is expected to approach southeast of Taiwan on Monday and pass through the Bashi Channel between Tuesday and Wednesday,
About nine Taiwanese are “disappeared,” detained, or otherwise deprived of freedom of movement in China each month, the Mainland Affairs Council (MAC) said yesterday. Between Jan. 1 last year and Aug. 31 this year, 188 Taiwanese travelers went missing, were detained and interrogated, or had their personal freedom restricted, with some questioned in airports or hotel lobbies, the council said. In a statement ahead of the Mid-Autumn Festival, the council urged people visiting China for any reason to be highly vigilant and aware of the risks. Of the reported cases, 50 people were “disappeared” after entering China, 19 were detained and 119 had
