What this page does and does not yet contain. This is the taxonomy pass. Every virus below carries its ICTV classification and the evidence that it infects people. Vaccines, antivirals, antibodies and disease-burden figures have not been searched yet — that is why the last column says so, rather than being blank or saying “none”. An empty cell would claim that nothing exists; this claims only that nobody has looked.
Taxonomy is copied by script from the ICTV Virus Metadata Resource and is never hand-edited. How a virus qualifies for this list, and which viruses are deliberately left out, is on the methods page.

Members with evidence of human infection
13 of this family’s species qualify for the index. Species with no human sequence evidence, and the commensal families left out altogether, are explained on the methods page.
