Taylor Swift’s “Patient Zero”: who is it about?

Swift has explained how the song began. She has not named the person it is about.

Swift told Capital FM that a friend had been contacted by an ex’s new girlfriend, who wanted to know whether the friend had gone through the same thing. Several people in the group had received similar calls.

What is the song’s point of view?

Swift said she wrote from the perspective of the former partner receiving that call. The story behind the song is a real conversation among friends—not a confirmed account of one named relationship.

Is it about a specific ex?

Swift has not identified anyone. Names circulating online are fan theories, not confirmation from the singer.
