Hantavirus cluster linked to m/v Hondius cruise travel

Andes virus has a segmented RNA genome, so the small (S), medium (M), and large (L) genome segments are analyzed separately. All available outbreak sequences are very similar, consistent with a single source of exposure and subsequent spread within the ship, though genomics alone cannot resolve transmission pathways. This interpretation is described in a preliminary analysis posted to virological.org. For more information on how to interpret phylogenetic trees like the ones seen below, see the Applied Genomic Epidemiology Handbook section on phylogenetic trees.

Some data in this build may be RESTRICTED-USE - meaning its use in preprints or publications is restricted. Please see the Pathoplexus Data Use Terms for more details.

Trees are embedded from full Nextstrain build using the Hodcroft Lab Andes virus segment trees.
