Abstract

IntroductionIn developed countries, several Hepatitis A outbreaks have been documented in the last years relating tosexual transmission, affecting mainly men who have sex with men. This work aims to describe the characteristics of the outbreak in the province of Seville from 2016 to 2018, as well as the vaccination campaign that took place to manage the outbreak. MethodsDescriptive study of the Hepatitis A incidence from 2016 to 2018 in males between 18 and 64 years of age in the province of Seville, as well as the vaccination coverage in males of that age in that period. Data collected from RedAlerta and Diraya Vacunas. ResultsFrom 2016 to 2018 in the province of Seville, 499 hepatitis A cases were diagnosed in males between 18 and 65 years of age. During this time, 4676 males between 18 and 65 were vaccinated against hepatitis A, with a mean age of 35. There was a drop in the numbers of vaccinations in 2017 coinciding with a vaccine shortage, after which the vaccination rate grew, accompanied by a decrease in cases (20%). ConclusionsHepatitis A is a public health problem that in countries with low endemicity, like Spain, is linked to high-risk groups, like HSH. The vaccine campaign is essential in the management of the outbreak, but so are the population's information and awareness.
