Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its venom is a strong neurotoxin, which attacks the nerves. It acts both before and after the nerve connects to the muscle, and it causes a strong, permanent block of nerve signals to the muscles in vertebrates. A muscle-damaging toxin called lemnitoxin has also been isolated from the venom.1

Ana hatari gani kwa watu?

Hatari kwa watu: Hatari sanaAnaweza kumuua mtu asiyepata matibabu.

It is not aggressive towards people, but it can bite to defend itself. The estimated lethal dose for an adult human is 5 to 7 mg of venom (dry weight). In laboratory milking, the average venom yield was 8 to 10 mg and the largest was 27 mg.1

Hufanya nini akiogopa?

It is not aggressive, but it can attack to defend itself when threatened.1

Akiuma

  • Mweke mtu bila kutikisika na mtulivu na umpeleke hospitali haraka, hata kama jeraha linaonekana dogo: dalili zinaweza kuanza saa kadhaa baadaye.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

1

The venom of this snake is strong enough to cause paralysis, because it blocks nerve signals to the muscles.1

2

It is one of the few snakes whose diet includes freshwater eels and gymnotiform fishes.1

3

It is nocturnal and digs in loose soil or leaf litter, so it spends much of its time hidden underground.1

4

It can live in disturbed land and near human homes, not only in deep forest.1

Kuvunja dhana potofu

Dhana potofu: Coral snakes are aggressive and will attack people.

Ukweli: This snake is not aggressive towards people. It only bites to defend itself.1
