In the caption, the actor explained that her sister has lupus, an autoimmune disease that causes inflammation to the joints, skins and other organs.
“My sister Kelly, who already has lupus, now has Covid-19. This is her hospital room. One of the Non-Mask wearers did this,” Stone wrote.
“She does not have an immune system. The only place she went was the pharmacy.”
The Basic Instinct star explained that in the US county in Montana where Kelly lives, members of the public cannot get tested unless they are symptomatic.
Once they have a test, it takes five days for them to receive their results, Stone said.
“Can YOU FACE THIS ROOM ALONE? Wear a mask! For yourself and others. Please,” she added.
In another Instagram post, Stone shared a video in which provided further details about her sister’s condition and how Covid-19 has impacted her family.
Stone revealed that Kelly’s husband Bruce is also in a Covid room in the same war “fighting for his life”, stating that the couple “stayed at home as long as they could”.
The actor said that her mother, who’s had two heart attacks, five stents and a pacemaker within the last five months, was unable to get tested, nor were the nurses who have been taking care of her sister and brother-in-law.
“Those nurses are risking their lives and cannot get tested,” she said, adding that she has been trying to get in contact with the governor of Montana and the health department, but has not been successful.
“They keep saying that the risks are so small and that you might not die and it’ll be fine, but I’m telling you what’s going on with my family,” the 62-year-old said.
“My grandmother died of Covid and my godmother died of Covid. My sister and her husband are fighting for their lives and my sister is not doing well.”
Stone ended her video by urging her followers to vote, expressing her support for Joe Biden and Kamala Harris.
