I think the best solution may be to keep her until you can find a good home for her. Maybe you can be able to foster her for cat village?
We found a abdonded cat that was beyond lovely. This cat was super people friendly but super cat aggressive. We found him a home but it took 18 months to find him a home where he would be the only cat.
Can you test her? Then if she is negative can you keep her and vaccinate her? Holding onto her until you can find her a good home/spay her? If you can't afford to do the above I would keep her in isolation and get her to the kitty village.
