In Spain, almost 400 confirmed cases of measles were reported in 2025, a higher figure than in 2024, when 227 cases were notified. The data referred to by the ECDC are preliminary, and we do not yet know whether, once they are confirmed or finalised, the downward trend will actually be maintained. In 2025 we have indeed experienced a higher number of imported cases from areas and countries that were undergoing major measles outbreaks. We have had many imported cases, which is why there were more cases in 2025. The current trend is that the incidence of measles is being maintained; in other words, we are still seeing cases now, at the beginning of 2026. This is to be expected, as measles is a strongly seasonal disease, with more cases mainly in the early spring months and at the end of winter — that is, February, March and April. We are already recording some cases at present, so while we are not saying the trend is increasing, at the moment we cannot say that it is declining either.
