Molecular epidemiology database

Norovirus sequences can be searched and compared to new sequences at the norovirus molecular epidemiology database (members only, see 'membership' at mainpage).

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.
See 'sequence typing tool' for a link to the tool and information on:

• reference set updates
• a small introduction
• the genotyping process in three steps
• regions used for typing. 

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.
