Aims This study aims to investigate the presence and spatial-seasonal variability of human fish viruses in coastal marine systems using Ravenna's harbour area (Adriatic Sea, Italy) as a model. Methods Results Human (noroviruses hepatitis A virus) one most threatening finfish pathogens, nervous necrosis virus (NNV), were investigated mussels living inside offshore harbour. Thirty-three 36·7% tested mussel samples resulted contaminated by respectively. different distribution was observed. detected mainly inner port sites during colder months, while NNV both harbour, warmer months. Conclusions The close city centre could be attributed wastewaters carrying pathogens environment this arises public health concerns, however, these limited canal winter can greatly reduce risk health. Regarding NNV, accumulation release viable mussels, represent viral source for susceptible finfish. These findings reflect epidemiological features infections indicate importance choose correct indicator monitor contaminations. Significance Impact Study high frequency contamination pointed out stresses imperative all habitats where natural value meets several recreational commercial activities such area. Particularly, novel starting point development more structured bio-monitoring program, order ensure improved environmental management safety areas.
