It's clearly a plural, and from the point of view here it's superfluous because in a dictionary the singular is defined; But it also raises some doubts about its definition. If it exists, I can't think of a phobia of what it could be; It would not be a metathesis of aibophobia, because it is invalidated by the plural /s/ , I thought then of an error by 945; 957; 953; 945; 969; (aniaoo "to harm") confusing the Greek letter /957;/ with the Latin /v/, but it's a very thick nonsense. It is more believable a typo from aviophobia, a spawn for "fear of flying in an airplane" that should not even exist as a word but in some places they use it.
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
