To type Noroviruses, several new tools and databases have been developed during the last couple of years.
Molecular epidemiology database
Norovirus sequences can be searched and compared to new
sequences at the norovirus molecular epidemiology database
(members only, see 'membership' at
A version of the database with public access to a subset
of the data, including the sequences, is also available.
Sequence typing tool
Norovirus sequences can be compared to a reference set in the
sequence typing tool to type the virus.

Transmission mode distinguishing tool
In order to increase the success-rate of identifying a
food-borne source of infection, a transmission mode distinguishing
tool was built based on data from the joint database as
part of a publication.
In the future we will continue to develop new tools
to facilitate detection and analysis of norovirus outbreaks.
