Human noroviruses (HuNoVs) are an important cause of epidemic and endemic acute gastroenteritis worldwide; annually about 700 million people develop a HuNoV infection resulting in ∼219,000 deaths and a societal cost estimated at 60 billion US dollars 1. The lack of robust small animal models has significantly hindered the understanding of norovirus biology and the development of effective therapeutics against HuNoV. Here we report that HuNoV GI and GII replicate to high titers in zebrafish (Danio rerio) larvae; replication peaks at day 2 post infection and is detectable for at least 6 days. HuNoV is detected in cells of the hematopoietic lineage, the intestine, liver and pancreas. Antiviral treatment reduces HuNoV replication by >2 log10, showing that this model is suited for antiviral studies. Downregulation of fucosyltransferase 8 (fut8) in the larvae reduces HuNoV replication, highlighting a common feature with infection in humans. Zebrafish larvae constitute a simple and robust replication model that will largely facilitate studies of HuNoV biology and the development of antiviral strategies.
