Unvaccinated four-year-old dies of suspected diphtheria in Palermo as cousin tests positive
Italian prosecutors have opened an inquiry after a four-year-old unvaccinated girl died of suspected diphtheria in Palermo and her vaccinated cousin tested positive.
A four-year-old girl, Anna Rosa Bartolotta, died from suspected diphtheria in Palermo, Sicily, marking what could be Italy's first fatal case of the disease since 1991. The child, from Palermo's ZEN neighbourhood, was not vaccinated against diphtheria, which has been mandatory under Italian law since 2017. Health authorities confirmed that her four-year-old cousin was subsequently admitted to Di Cristina Children's Hospital with symptoms and tested positive on 22 August 2026. Hospital officials noted that the cousin is vaccinated and remains in stable condition.
Arnas Civico medical director Domenico Cipolla reported on the cousin's condition:
He is improving clinically. We also measured the anti-diphtheria immunoglobulins, which are present at protective levels, and we are keeping him under observation and in isolation while monitoring all clinical functions.
Clinical deterioration and timeline
Anna Rosa was first brought to the Cervello Hospital emergency room at 22:00 on 13 August 2026 suffering from fever, vomiting, and feeding difficulties. Medical staff discharged her with a diagnosis of exudative tonsillitis, advising the family to return if symptoms worsened. Two days later, on 15 August 2026, her parents returned after the fever failed to subside. On 16 August 2026, doctors intubated the child for respiratory failure and transferred her to the pediatric intensive care unit at Di Cristina Children's Hospital. She died on the night of 19 August 2026 from multiple organ failure caused by diphtheria toxins.
- Initial emergency admission at Cervello Hospital with fever and discharge with tonsillitis diagnosis
- Hospital readmission after persistent fever, weakness, and feeding difficulties
- Intubation for respiratory failure and transfer to Di Cristina pediatric intensive care unit
- Death of four-year-old Anna Rosa Bartolotta from bacterial toxin complications
- Confirmation that vaccinated four-year-old cousin tested positive while recovering
Legal inquiries and parental choices
The Palermo Public Prosecutor's Office opened an investigation, placing the child's body in custody for an autopsy to confirm whether Corynebacterium diphtheriae caused the death. Carabinieri officers seized medical records from the treating facilities to examine whether early diagnostic delays contributed to the outcome. Investigators are also examining parental liability, as the parents declined routine vaccinations for their daughter. The child's mother, Manuela Maggio, posted on social media accusing hospital doctors of incompetence and underestimating her daughter's initial symptoms.
Containment and vaccination appeals
Following the death, hospital personnel who treated the patient received antibiotic prophylaxis. Around 20 members of the extended family attended vaccination clinics to receive the hexavalent shot. Infectious disease specialist Antonio Cascio urged health teams to identify patient zero among asymptomatic carriers, while noting that broader community spread remains low. Regional health councillor Marcello Caruso issued a direct appeal to families:
Parents, vaccinate your children without delay to protect them from diseases that have been eradicated thanks to vaccination campaigns.
Former Ministry of Health prevention director Francesco Vaia addressed the public reaction to the case:
The death of the four-year-old girl in Palermo is a tragedy that deeply affects us. As doctors, as parents, as grandparents. Before any other consideration comes respect for a child who is no longer here and for a family experiencing unspeakable grief. This is certainly not the time to point fingers at the parents.
Health specialists noted that the standard hexavalent schedule begins at two months of age, with subsequent childhood boosters required to maintain protective antibody levels against the bacterium.
