Unvaccinated child dies in Palermo from suspected diphtheria as prosecutors launch inquiry

Hospitalization and fatal course

A young girl, identified as Anna Rosa Bartolotta and reported as either three or four years old, died overnight between 19 and 20 August 2026 at the Children's Hospital in Palermo. She first presented at the hospital on the preceding Thursday with symptoms including fever, vomiting, and loss of appetite. Medical staff discharged her following initial tests with a diagnosis of tonsillitis and instructed the family to return if symptoms persisted. Despite antipyretic medication, her high fever continued over the following two days.

On Saturday, 15 August 2026, the child was brought in critical condition to Palermo's Cervello Hospital, where doctors intubated her. Given her deteriorating state, medical staff transferred her to the pediatric intensive care unit at the Di Cristina Children's Hospital. As multi-organ failure developed, surgeons moved her to cardiac surgery to place her on extracorporeal membrane oxygenation (ECMO) life support. The intervention failed to arrest the decline, and she died in the early hours of Thursday.

Family background and vaccine refusal

During clinical assessments, medical personnel established that the child had received no mandatory vaccinations since birth. The family, residing in the ZEN neighborhood of Palermo, stated they withheld immunizations out of fear that vaccines were responsible for autism, citing an autistic relative. The Italian national immunization calendar prescribes the hexavalent vaccine during early infancy, covering diphtheria alongside other mandatory pediatric immunizations.

Scientific consensus and public health agencies confirm that no causal link exists between vaccines and autism. Italian health authorities note that widespread vaccination coverage is necessary to maintain community immunity, which shields vulnerable individuals unable to receive vaccinations due to specific medical conditions. Sicily currently records the highest proportion of non-immunized children among Italian administrative regions.

Judicial inquiry and medical verification

The Palermo Public Prosecutor's Office seized the child's body and ordered an autopsy to determine the precise cause of death. Investigators opened a formal inquiry into the circumstances surrounding the absence of mandatory childhood vaccination and the clinical protocols applied during her initial hospital discharge. Regional authorities are also conducting laboratory testing to confirm whether Corynebacterium diphtheriae caused the fatal infection.

Regional Health Assessor Marcello Caruso confirmed the testing process on Thursday.

We are conducting tests to confirm whether it is diphtheria. The results will be available later.

Diphtheria epidemiology and vaccination coverage

Diphtheria is an acute infectious bacterial disease caused by Corynebacterium diphtheriae, with certain strains generating toxins capable of damaging the heart, kidneys, and nervous system. The infection primarily targets the respiratory tract, forming thick membranes across the throat and tonsils that obstruct breathing, and carries a case fatality rate between 5% and 10%. Vaccine formulations available since 1920 use an inactivated toxoid that triggers protective antibody production without causing toxicity.

The disease had disappeared from Italy for more than a decade following national vaccination campaigns. Ministry of Health records indicate five total cases in Italy since 2000. Between 2015 and 2017, Italian health services registered eight confirmed infections, of which only one was a toxin-producing cutaneous case, while the remainder involved non-toxigenic strains. Globally, World Health Organization figures recorded approximately 2,500 fatal cases in 2011 and 4,680 reported cases in 2013.
