Meleagrid alphaherpesvirus 1

Taxonomy pass, October 2026

ICTV species Mardivirus meleagridalpha1, family Orthoherpesviridae. What it is, and what exists against it.

These are animal vaccines. None of them is a vaccine for people. Every product on these pages is authorised for the animal species named in its row, by the UK Veterinary Medicines Directorate. A product licensed for cattle or poultry says nothing about whether protection exists for a person, and several of these viruses do not infect people at all.

Host evidence

Counts of nucleotide records annotated with that host. Evidence of provenance, not a statement of host range.

Where it occurs

Not searched yet. No country-level occurrence data has been curated for this virus. The WHO reported-case data on this site covers a limited set of diseases; a virus outside it gets no map rather than an empty one.

What it does

Not searched yet. Burden, severity and transmissibility figures have not been curated for this virus yet. When they are, each will carry the exact sentence from its source.
