A TODDLER has died after being bitten on the neck as he slept by a mysterious animal leaving his parents heartbroken. Brayan Gabriel Duarte dos Santos, from Santa Catarine, Brazil, was bitten in his sleep, which led to swelling and eventually organ failure. Heartbreak: Marisete’s two-year-old was killed by a mysterious creature Medics believe the bite was caused by a centipede Medics are now baffled as to what caused the bites – with an autopsy being ordered to try and shed light on the matter. Brayan’s mum, Marisete dos Santos, at first thought her son had a bruise and did not immediately notice the bites. She eventually took her son to the pharmacy where they were recommended to take Brayan to hospital. He was taken to the Alto Vale Regional Hospital on Saturday where the bite marks on his neck and swelling were treated, but died a day later after his health condition worsened. Experts in the city of Lages are now working to determine what caused the bite marks, believing the source could be a centipede. Centipede bites in which they inject venom into the wound are rarely fatal but are regarded as particularly dangerous for children, especially if they develop an allergic reaction.
