No. Take a good look at those three parts of the series:
cause AIDS (verb + direct object)
produce cancer (erb + direct object)
even kill (adverb + verb)
Do you see that they are not the same? That they are not parallel?
Go back to the original sentence and take the series apart as I did in your sentence. What do you find?
Correct this: The virus may cause AIDS, cancer, or even kill.
Do I need to add a word in front of cancer? Would this be correct?
The virus may cause AIDS, produce cancer, or even kill.
