Abstrakt:	Objective: In Galicia, the incidence (I) of hepatitis A (HA) is low and the susceptibility is 51% in adults (18-64 years). Between 2016 and 2018 the cases increased, mainly in men. We intend to describe the cases of HA in Galicia during this outbreak period (PB), compare them with the pre-outbreak period (PPB), and the interventions performed. Methods: Descriptive study of the cases of HA declared between 2016-18 (PB), compared to those from the previous period (2010-2015, PPB). Cases recorded in the mandatory notification system (general practice, hospitalization and microbiology) from 2010 to 2018 were included. For the pre-outbreak period 2010-2015 (PPB) it was calculated the average of cases/four-week period to compare observed/expected cases; the incidence (I) [cases/100,000 inhabitants (c/105h)] by sex and age was compared with the PPB through the Relative Risk (RR). It were sent messages with recommendations through men who have sex with men (MSM) reference websites. Results: The outbreak lasted 80 weeks (september of 2016 to march of 2018). The incidence was 3 cases/105h in men and 0.5 cases/105h in women. Compared to the PPB, the RR-PB in men was 4.8 (95%CI=4-7) and 20.4 (95%CI=5-87) in 40-44 years. 42% of men declared to have relationships with other men (57% in 20-30 years). At the end of 2016, a message with recommendations (specially vaccination) was sent via Wapo (promoted to MSM through one of its reference websites), where 331 entries were registered. Conclusions: HA's incidence, in Galicia, increased in 2016-2018 by an outbreak in MSM. We found an increased susceptibility among young people which makes necessary to insist on the vaccination of groups at risk. Competing Interests: Disclosure María Jesús Purriños-Hermida has a temporal consulting agreement with Shionogi SL, for the realization of a decalogue on the importance of antimicrobial resistance. The rest of the authors report no conflicts of interest in this work.
