Davi Nunes Moreira, 14, lost his life after participating in a disturbing online challenge. According to the New York Post, he injected a mixture of dead butterfly remains and water, which caused severe health complications. Moreira's cause of death is still under investigation, with authorities exploring the possibility that toxins from the butterfly remains may have caused septic shock, a condition when an infection causes dangerously low blood pressure and organ failure. While police have initiated an official investigation, they have not yet confirmed whether Moreira was directly influenced by an online challenge. Reports suggest that he had denied any link to the trend before his death. According to the Daily Mail, local media reported that Moreira's father discovered a syringe under his pillow while cleaning his room. The report also said that authorities believe the autopsy results will provide clarity on the exact cause of death. Experts point out that butterflies contain bodily fluids that haven't been fully studied for their effects on human health, Daily Mail reported. Many butterflies feed on toxic milkweed plants as caterpillars, making them naturally poisonous to predators. However, experts believe that the toxin levels are usually too low to cause harm to humans, especially in small quantities. In April 2024, social media influencer Thammy MC, who has two million followers, suffered necrosis after taking part in a viral challenge. According to the reports, Thammy stood in an ice bucket for an extended period, which caused her feet to turn black due to frostbite. Doctors warned her of the risks of blood clots and severe tissue damage, stating that if she had stayed on the ice for just one more minute, she could have lost skin tissue.
