   • 2018 February 7, Dora Niyego, “El Antisemitizmo De Oy”, in Şalom‎^[4]:

     El antisemitizmo es un prejudizio, komo un virus.

     Antisemitism is a prejudice, like a virus.

Via rhotacism from Proto-Italic *weizos, from Proto-Indo-European *wisós (“fluidity, slime, poison”). Cognates include Sanskrit विष (viṣá), Ancient Greek ἰός (iós, “poison”), Tocharian B wase, and Middle Irish fí. The neuter gender of this term despite its nominative singular ending in the masculine second-declension -us is possibly a relic of this term's inheritance from a neuter s-stem.^[1]

vīrus n sg (genitive vīrī); second declension

1. venom (a poisonous substance secreted by animals or plants)
2. a plant- or animal-sourced substance with medicinal or magical properties
3. a liquid element that makes something taste or smell bitter or acrid
   1. (transferred sense) bitterness, acrimony (of speech, manner or disposition)
4. (New Latin) a virus (infectious organism)

Second-declension noun (neuter, nominative/accusative/vocative in -us), singular only.

• There is also the heteroclitic genitive singular vīrūs.
• When used in modern biology with the same meaning of English virus, a plural can be formed using the same suffixes of regular neuters of the 2nd declension (i.e., vīra, vīrōrum, vīrīs, vīra, vīrīs, vīra):^[2]
