Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its venom is cytotoxic, which means it destroys tissue. It also contains digestive enzymes that disrupt blood flow and stop blood from clotting. In its prey, these effects cause severe internal bleeding.1

Ana hatari gani kwa watu?

The snake is shy and avoids humans when it can. Most bites in Ontario happened after people handled it or accidentally stepped on it. Only two deaths from its bites have been recorded in Ontario, and in both cases the victims did not receive proper treatment.1

Hufanya nini akiogopa?

It is shy and tends to withdraw from people rather than confront them.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

Ukweli

It is a pit viper, a family that includes all rattlesnakes, and it is the only venomous snake in Ontario.1

Mothers and newborns stay together for a few days, until the young shed their skin for the first time.1

Females often do not breed every year, usually having a two-year breeding cycle.1

Its populations have declined so much that it has disappeared from many of its former areas, and now survives mainly in small, isolated groups.1
