Viral Host Range database, a resource for virus-host interactions studies

How do I search for the host of a virus? If answering this question is trivial for some human pathogenic viruses, it is more puzzling for viruses in general. The Viral Host Range database (VHRdb) gives access to the experimental data to answer this question. The aim of the VHRdb is to provide to the community the data generated by scientists documenting the host range of their favorite virus through an easy (copy/paste) contribution process including benefits. Indeed, VHRdb integrates analysis tools to compare experimental datasets in many ways. Searching for the host range of a virus, or the other way around has never been easier!

By sharing host range tests published but yet not in a searchable format, you will give a new value to your work and prevent scientists to perform the same tests again and again.
