The Dirección General de Salud Pública of the Servicio Canario de la Salud (SCS) on Monday, 24 August 2026, declared the measles outbreak reported on Tenerife officially over. No further infections linked to the cluster had been identified after the prescribed observation period, the authority said. The chain of transmission is therefore considered to have been interrupted.
According to the authorities, the outbreak involved six people in total. A four-year-old child was identified as the index case; the illness was confirmed after the child returned to the United Kingdom and was therefore not counted as part of local transmission on Canary Islands . Five further cases were recorded on Tenerife. They were mostly mild; two people were treated as a precaution at hospital and later discharged. Among those locally affected were an employee of the hotel where the index case was staying, two staff members at a hospital visited by the hotel employee, and a member of the Cuerpos y Fuerzas de Seguridad del Estado, who had also visited this health centre. One other person was recorded as a contact case.
The health authorities stress that classifying the first case as imported means it is not recorded as a local case in the regional outbreak statistics. At the same time, the sequence of exposure—accommodation, healthcare and security personnel—illustrates why contact tracing was concentrated in settings with many contacts. The outbreak was managed in accordance with the applicable protocols: identifying and notifying contacts, checking vaccination status, taking post-exposure measures where appropriate, and continuing surveillance until the relevant periods had elapsed without any new cases. No personal details were released.
The Consejería de Sanidad Against this background, renewed its call for vaccination. Full vaccination in line with official recommendations remains the most effective way to prevent measles outbreaks. The SCS noted that high vaccination coverage in the population significantly reduces the risk of secondary transmission, especially in settings with high levels of contact, such as hotels, hospitals and security services.
With the formal closure, the event is administratively concluded. The authority nevertheless stressed that imported cases can occur at any time. Accurate diagnosis, prompt reporting and consistent implementation of standard measures therefore remain essential to contain isolated introductions quickly and prevent local chains of transmission.
