The Who's the Boss? star revealed on Instagram Wednesday that she had been sick for two weeks. She wrote that "everything hurt," she lost her sense of smell, couldn't breathe and "couldn't keep food in me." "I basically had every Covid symptom," Milano wrote. "At the very end of march I took two covid19 tests and both were negative. I also took a covid antibody test (the finger prick test) after I was feeling a bit better. NEGATIVE." She decided to get yet another test, resulting in a positive test for coronavirus antibodies. "I had Covid19," she wrote. "I just want you to be aware that our testing system is flawed and we don’t know the real numbers," she explained. "I also want you to know, this illness is not a hoax. I thought I was dying. It felt like I was dying."
