According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.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.
