The black-necked spitting cobra is a venomous snake found mostly in sub-Saharan Africa. It can squirt venom from its fangs at a threat, and that venom can cause permanent blindness if it gets into the eyes. Its colours vary a lot from place to place.1

Zahar quvvati

Sepadi yoki tupuradi

Uning zahari (chaqsa yoki nish ursa) nima qiladi?

Its venom is mostly cytotoxic, meaning it destroys cells, and it also has typical elapid neurotoxic (nerve-attacking) effects and cardiotoxic (heart-damaging) components. A bite causes severe bleeding from the wound, tissue death around the bite, and difficulty breathing. Venom in the eyes causes extreme burning pain, loss of coordination, partial loss of vision, and permanent blindness.1

Odamlar uchun qanchalik xavfli?

Its venom is medically significant. The death rate for untreated bites is about 5 to 10%, and under 1% in areas where it is common. When death occurs, it is usually from paralysis of the diaphragm, the muscle used for breathing.1

Qoʻrqqanda nima qiladi?

It spits venom from its fangs at a threat, reaching up to 7 metres with good accuracy. It also bites readily, even with only slight provocation.1

Agar chaqsa yoki tupursa

  • If venom gets into the eyes, it should be washed off, because permanent blindness can follow if it is not. Anyone bitten should get medical treatment, as untreated bites carry a much higher risk of death.1
  • Odamni qimirlamay va xotirjam tut, uzuk va siquvchi narsalarni yechib ol va tezda kasalxonaga olib bor: davosi zaharga qarshi zardob.
  • Agar zahar koʻzga tupurilgan boʻlsa, darhol koʻzni koʻp toza suv bilan yuv.

Xavfsiz boʻl

  • Hech qachon yovvoyi hayvonga tegma, uni tutma yoki jigʻiga tegma, hatto kichkina boʻlsa ham va hatto uxlayotgan yoki oʻlik koʻrinsa ham.
  • Unga joy ber. Agar duch kelsang, xotirjam boʻl, sekin orqaga chekin va uni oʻz yoʻliga ketishiga qoʻy.
  • Agar biri seni chaqsa yoki koʻzingga zahar tupursa: xotirjam boʻl, qimirlamay tur, favqulodda yordam raqamiga qoʻngʻiroq qil (112, 000, 911) yoki tezda kasalxonaga yet. U qanday koʻrinishda ekanini eslab qol, surat yordam beradi.
