Brazilian model Mariana Bridi passed away on the weekend at the young age of 20.

Mariana recently came down with a misdiagnosed urinary tract infection – an ailment that affects a great deal of young women and is easily treated with antibiotics. However, by the time it was finally properly diagnosed, the infection had spread, causing her to have both hands and feet amputated. The strain of infection mutated to a point where it was resistant to antibiotics and she eventually lost the fight on Sunday morning.

According to the AP:

Bridi had been in the hospital in the city of Serra in Espirito Santo state since Jan. 3. Doctors originally diagnosed her with kidney stones in December, local media said. But as her condition worsened, she was diagnosed with a urinary tract infection that spread. The cause of the infection was not immediately known. It reduced the flow of oxygen to her limbs, causing her feet to be amputated last week and her hands this week. Part of Bridi’s stomach was also removed as doctors tried to contain internal bleeding, local media said. Health officials on Friday said Bridi was not breathing on her own and was undergoing hemodialysis at a hospital in the city of Serra.

This is shocking to me. Urinary tract infections are the sort of thing that you take for granted as being so easy to treat, nothing more than an irritation and a hassle. No one expects to DIE from it. What a horrible tragedy.
