what is plural of viral
Virus is not attested in the plural in Latin, and is of a rare form (2 nd declension neuter in-us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses.he Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus.
