The use of "who" on non-human subject such as a virus

A question struck me one day when I was writing a blog post and wanted to use the relative pronoun who on non-human subject such as a virus. I had seen many examples before where this pronoun, which is used chiefly to refer to humans, is being used on non-human subjects and they appear idiomatic:

Edwina, the Dinosaur Who Didn't Know She Was Extinct

He plays Andrew Martin, a robot who, over 200 years, discovers what it means to be human. (From a 1999 edition of USAToday. I discovered it on COCA.)

They doubtless were Thark warriors who had been sent out to capture us. (From A Princess of Mars.)

In common usage ‘animals’ only refers to animals who aren't human

If my analysis is correct, it appears that the use of who on non-human subjects is acceptable when there are signs of personification (example 1), or the non-human subject actually possesses human-like properties and resembles a human in many ways (example 2, 3).

In example 4 I find it a little bit tricky to justify the use of who. The reason why the author chose the pronoun who rather than which or that probably has to do with how the expression reads and sounds, which he stated in the endnote as the reason why he/she didn't use the phrase animals other than humans. So here is my question:

It was due to the dengue virus who infected my stromal cells and impaired my bone marrow.

Can I justify the use of who in this sentence I wrote by giving a similar argument such as I like the way it reads and sounds as the presence of who makes the virus seem like a person and that's my intention? Or in other words, will the sentence be considered ungrammatical since I use the pronoun who instead of that or which, even though my intention is to make in-human subject seem like a person?

You can quasi-justify anything, realistically speaking. But why bother? Not only is it linguistically and even grammatically iffy at best, it is going to throw off a good chunk of your more perceptive audience members if not for a mere second. For the purposes of communication, it would be hard to justify it as it does little to clarify your statement, rather it will most likely obscure it.

Going along with the idea of good communication, I think the only way 'who' would be appropriate for the virus is if your are attempting to convey to your audience that the suffering through the virus instilled a sense of bitterness and symbolic hatred towards this thing enough that you would anthropomorphize it as to provide further clarity on your feelings.

So it depends on what message you are trying to communicate, but more than likely it would not benefit you to use who as opposed to almost anything else (which, that, etc).

Who is used to refer to people and to non-human objects for whom the speaker has a degree of affection. You might reasonably say, "Meet my dog, Fido. He's the one I was telling you about who bit the postman." But, you'd probably say, "There is the snake that bit my dog." Dengue is the virus that is making me sick. But, "I've been developing virus vectors to deliver genomic DNA in a therapeutic setting for the past five years. I've worked with over 178 strains, but this one, MOS-bp-234, is my favorite little phage. He's the one whom I'd want delivering the adenovirus vaccine up my nose. In other words, successfully using who/whom for a non-human requires a degree of affection for the antecedent and a fairly casual register.
