Spat at while on a walk

I was walking down the street in Manhattan with my partner and a woman wearing a mask turns to us, pulls down her mask, and says with disgust “the virus came from China.” We were in shock, and that’s when she spat in our direction. She kept walking and when I realized what happened, I called her a racist and I couldn't hear what she said but she said something back and kept walking, and that was the end of the interaction.
