Often humans tend to get attracted to the wilderness and forget the dangerousness of the species that are wild animals. When we talk about chimpanzees, those can form a good bond with human beings but they're generally under the category of wild animals.
If provoked, they would attack you as well. Since chimps are physically stronger than most humans, it could lead to really disastrous consequences if one gets attacked by a chimp.
That's what happened with Charla Nash after being attacked by a friend's pet chimp in 2009. Check out her entire story.
She was visiting the home of her close friend Sandra Herold when the incident happened. Sandra was also her employer and owned a pet chimpanzee.
He wasn't a very violent chimp and barely threw any tantrums.
Only after Sandra Herold called for the police to stop the attack, did the attack cease. The police had to shoot the ape dead in order to stop the attack on Nash.
As you can see, her entire face was disfigured to an extent that she couldn't even be recognized.
The doctor who operated on Charla also had to undergo counseling because he felt traumatized by the entire incident.
During her hospital stay, she met with many doctors who helped her plan the next step of treatments and surgeries. She appeared on the Oprah Winfrey show and discussed about her tragic incident.
A team of doctors worked on her disfigured face and body by applying various skin and bone grafts to her body.
The facial transplant was a success but the hand transplant wasn't.
She also had a Captive Primates Saftey Act issued which doesn't allow the transport of chimps across the state lines.
Although, her smile is still crooked, but her face has healed remarkably. Wish you all the luck Charla!
