"You brought the virus over"

I was walking my dog at the park and a man and a woman approached me. The woman stuck her face up close to my dog, approaching without asking for permission. I was not comfortable with her approaching as I had seen her earlier harassing an older man, and I did not know how my dog would react. She started to bow to me in a mocking way, and when I told her to not get any closer and to stop, she got aggressive with me. She said, "I know you're Chinese. I have heard about you. You brought the virus over." I yelled at her that that was racist and to leave me alone. As I started to walk away, she hurled more insults and said, "I'm going to shoot you! I'm going to shoot your dog" as well as threatened to call the police and accuse my dog of biting her to put my dog down. I yelled at her that she could not say those things and she charged at me; however, because of her current state, she fell flat on her face and her boyfriend pulled her back from progressing any further. I did not report this to the police at the time.
