Abstract

From April to October 2017, 27 cases of Hepatitis A (HA), 22 male and 5 female, were reported in Cosenza (South Italy). The median age of cases was 32 years (range 3-49 years). Out of 21 male adults, 14 were identified as men who have sex with men (MSM). Phylogenetic analysis was conducted in 15 cases and revealed two distinct sequences of genotype IA linking to clusters recognised in MSM in other European countries in 2016; genotype IB was recognized in only 2 cases. The report confirms that HA is an emerging issue among MSM. As suggested by the WHO, in countries with low HAV circulation, vaccination programmes should be tailored on local epidemiological patterns to prevent outbreaks among high risk groups and eventual spill-over of the infection into the general population.
