Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its bite is painful. The venom contains neurotoxins, which attack the nerves. Several neurotoxins that are specific to crustaceans and insects have been found in it. The bite is fatal in rare cases.1

Ana hatari gani kwa watu?

Hatari kwa watu: MbayaKuumwa kunahitaji daktari. Vifo ni nadra sana.

Its bite is painful and can be fatal in rare cases. Epidemics of bites have been reported, and Ukrainian farm workers have been bitten in the fields. In Kazakhstan, where it is called karakurt, it has been reported to bite and kill camels. Only the female's bite is dangerous to people and cattle, because the male cannot get through the thick outer skin.1

Akiuma

  • Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.

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
