A student, Letícia Oliveira, who suffered poisoning after a swimming class at C4 Gym in East São Paulo, has been discharged from the hospital after a week-long stay, four days of which were in intensive care. She attended the class on February 7 with her three-year-old daughter, during which another attendee, Juliana Faustino Bassetto, tragically fell ill and later died. Letícia expressed her emotional reunion with her daughter upon release and recollected the strong smell of chlorine during the class, which she believes may have contributed to her illness.

The incident has raised significant concerns about safety protocols at the C4 Gym and has led to an ongoing police investigation. Letícia’s husband also faced health issues as he reportedly experienced suffocation while in the pool. This grim event raises questions not only about the gym's operational practices but also about the broader implications for public safety in facilities that accommodate children and families.

Letícia and her family demand justice, emphasizing that numerous children were present in the same swimming pool during the tragic event. Although the gym's owners have refrained from giving public statements, their lawyers have stated that they are cooperating with the investigation, which is expected to be thorough and fair. As the story develops, it highlights the critical need for accountability in recreational facilities, particularly those catering to vulnerable populations such as children.
