Milano wrote she "couldn’t keep food in me," which she said caused her to lose 9 lbs. in 2 weeks. "Everything hurt. Loss of smell. It felt like an elephant was sitting on my chest. I couldn’t breathe," she wrote alongside a photo of herself from April using what appears to be a breathing machine. "I was confused. Low grade fever," she continued. "And the headaches were horrible."

However, the Centers for Disease Control and Prevention has warned that the antibody tests currently available may not be accurate and should not be used to determine if someone is immune to COVID-19. As of Thursday, there have been at least more than 4,832,400 cases of COVID-19 in the United States and 158,500 deaths from coronavirus-related illnesses, according to The New York Times database.
