The knowledge of the baseline incidence rates of intussusception among infants in Cuba are necessary to introduce the rotavirus vaccine into the Cuban immunization schedule. With the aim of characterizing the clinical presentation and epidemiology of intussusception a surveillance study was performed in children less than 1 years old with intussusception, in the pediatric surgery service at the Centro Habana Pediatric Hospital in Havana city between November 2017 and April, 2018. This study is the precursor of an active sentinel hospital surveillance for intussusception in children under 1 year of age, as a part of the project Rotavirus vaccine promoted by Instituto Finlay de Vacunas. Data were collected for each notified case by surgeons using a brief study questionnaire (Sentinel surveillance file for intussusception). A total of nine patients were diagnosed with intussusception, most cases presented at 5 months of age (44.4%), and all cases were confirmed by abdominal ultrasonography. The incidence of intussusception was 1.41%. The most frequent symptoms were rectal bleeding (77.8%), irritability (66.7%) and vomiting (55.6%). Intussusceptions reduction by non-surgical methods was used in eight cases, mainly air enema (62.5%). These results are now available to build the body of scientific evidence for baseline rates of intussusception in children less than 1 year of age, prior to the introduction of the rotavirus vaccine in Cuba.
