"One of you Non-Mask wearers did this," Stone said in a post Sunday.
Stone's post comes as more than 5.4 million people have been infected and 170,052 have died from the coronavirus in the United States, according to data from Johns Hopkins University. Health officials have expressed concern that as the pandemic drags on, some Americans are becoming complacent with health precautions and allowing for more spread.
Stone's sister, Kelly, had lupus before being diagnosed with Covid-19, according to the post. Her sister has a weakened immune system and only went to the pharmacy before she was infected, Stone said.
Stone shared a picture she said was of her sister's hospital room.
"Can YOU FACE THIS ROOM ALONE?" she asked.

Stone called on her followers to abide by precautions against the virus's spread.
