Health authorities from the Canary Islands Health Service (SCS) have officially reported 6 confirmed cases of Hepatitis A, all involving minors and located at a nursery school on the island. The transmission's origin has been traced to this educational center, prompting the immediate implementation of an epidemiological contingency protocol to prevent the virus's spread.
The initial case, known as the 'index case,' was a student at the nursery. Following its confirmation, an exhaustive contact tracing effort identified five additional infected minors within the same school environment. According to official SCS sources, the clinical condition of those affected is favorable. Two minors have required hospitalization due to initial complications, while the remaining four are under home observation.
Health authorities have officially notified the National Epidemiological Surveillance Network (RENAVE) and the Gran Canaria Primary Care Management has launched mass screening among those associated with the affected school. The primary strategy to contain the outbreak involves post-exposure vaccination, with the vaccine being administered to unvaccinated students and staff. Experts emphasize that this immunization is effective when given before the virus reaches an advanced incubation stage.
Educational authorities have clarified that closing the school or implementing extraordinary structural isolation measures are not necessary. However, strict adherence to daily hygiene practices in classrooms and homes has been mandated. Hepatitis A virus transmission occurs via the fecal-oral route, primarily due to inadequate hand hygiene or ingestion of contaminated water or food.
Three essential hygiene practices are being emphasized: systematic hand washing after using the restroom, changing diapers, and before eating; thorough disinfection of high-risk surfaces like diaper-changing areas and common restrooms; and temporary isolation of infected individuals for at least seven days after symptom onset.
In children under six years old, the infection is often asymptomatic, making them silent vectors of transmission. In adults, symptoms are more pronounced and typically include sudden high fever, general malaise, acute abdominal pain, persistent nausea, vomiting, extreme fatigue, jaundice (yellowing of skin and eyes), dark urine, and pale stools. Hepatitis A causes acute liver inflammation but rarely leads to permanent liver damage. Treatment focuses on rest, hydration, and a bland diet.
