According to Espirito Santo Health Secretariat, 20-year-old Bridi is fighting a generalized infection which caused the amputation of both her hands and feet last week after the flow of oxygen to her limbs got compromised. Authorities said Bridi’s condition deteriorated overnight and was changed from "serious" to "very serious". (AP Photo/ Octavio Bastos/ NOROCK )
