[The extended contact tracing: the experience of Prevention Department of the Health Authority of Trapani Province (Sicily Region, Southern Italy)].

During the spread of SARS-CoV-2 virus, contact tracing proved to be a very effective public health tool. Within the local health authority of Trapani (Sicily Region, Southern Italy), contact tracing was managed by physician, prevention technicians, and administrative from the Health Prevention Department who were trained and updated during the evolution of the epidemic. Contact tracing has been extended to migrants who arrived in Trapani with the landings. Extended contact tracing had some critical factors related to language barriers, which reduced the effectiveness of the telephone contacts and psychological counseling during tracing, up to the loss of definition of high or low risk contacts among both migrants and rescuers. The team made up of workers from the Health Prevention Department, the Global Health Center, and Cultural Mediators was important in effectively managing the critical issues. The high number of cases occurred during the outbreak of COVID-19 in January 2022 has shown difficulties to support the contact tracing in this phase.
