Norovirus Typing Tool

This tool is designed to use phylogenetic methods in order to identify the Norovirus genotype of a nucleotide sequence.
The most recent update includes addition of new rare genotypes and a new GII.4 minor variant.
New names are followed by old names in parenthesis on the results page and further described on the report page.
Note for batch analysis: The genotypetool accepts up to 2000 sequences at a time.


Submit one or more FASTA sequences to be typed individually. If you have raw NGS reads (short reads or long reads), please use the Genome Detective Platform to assemble first. Subtyping tools will be linked in the results.
