A British tourist, who visited Tenerife unaware of carrying measles, has been the source of a new outbreak in the Canary Islands. UK health authorities confirmed the infection after the minor returned home, notifying the archipelago.
The subsequent three infections occurred among individuals who had direct contact following the initial exposure. According to sources from the Directorate General of Public Health, those affected include an employee of the hotel where the minor stayed, a healthcare student intern, and a member of the state security forces who encountered the hotel employee at a health center on the island.
None of the three secondary cases were vaccinated against measles.
These three individuals, aged between 45 and 55, belong to a demographic group for whom systematic vaccination was not standard during their childhood. The Ministry of Health immediately activated epidemiological surveillance and contact tracing protocols to contain the virus's spread, maintaining monitoring of potential exposures.
With these new cases, the Canary Islands have recorded 23 measles infections so far in 2026. Of these, 18 are linked to a previous outbreak on La Palma that began in October 2025, one was an isolated case in April, and the current four are part of the active cluster in Tenerife.
The Ministry of Health reiterates the importance of completing the measles vaccination schedule, considering it the most effective preventive measure. The MMR vaccine is administered in two doses in the Canary Islands (at 12 months and three years of age). Furthermore, it is recommended that adolescents and adults born after 1978 who have not had the disease or cannot prove they received both doses should review their vaccination status.
Health authorities warn that the rise in cases across several European countries in recent years is associated with declining vaccination coverage. Therefore, they emphasize that vaccination is the primary barrier to preventing the resurgence of this disease, which Spain has aimed to eradicate for over two decades.
