Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

The venom contains cytotoxins, haemotoxins and myotoxins. Cytotoxins damage cells, haemotoxins affect the blood, and myotoxins damage muscle. Severe bites can cause necrosis (death of tissue), shock, spontaneous bleeding inside the body, and kidney failure. Many patients also develop coagulopathy, a condition where the blood cannot clot properly.1

Ana hatari gani kwa watu?

Hatari kwa watu: Hatari sanaAnaweza kumuua mtu asiyepata matibabu.

The venom is potent enough to kill sixteen people. In one study of 29 bites in São Paulo state, Brazil, three patients aged 3, 11 and 65 died from respiratory and circulatory failure, even with large doses of antivenom in intensive care. Six patients had necrosis, and one of them lost a limb to amputation. Bites from snakes over 50 cm long caused the most severe effects.1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Hufanya nini akiogopa?

It is described as very aggressive in behaviour.1

Akiuma

Mweke mtu bila kutikisika na mtulivu, weka kiungo kilichoumwa usawa wa moyo, ondoa pete na vitu vinavyobana, na umpeleke hospitali haraka.

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
