HELENA, Mont. — Actress Sharon Stone is criticizing the availability of COVID-19 testing in Montana, where her sister and brother-in-law are hospitalized with the respiratory virus.

Stone posted a video on Instagram Sunday expressing frustration that there aren’t enough tests for front-line workers and people who have had direct contact with someone who has COVID-19, “like my mother, who’s had two heart attacks, five stents and a pacemaker in the past five months.”

Her mother wasn’t tested because she wasn’t symptomatic, despite her underlying health conditions, Stone said.

Stone’s sister, Kelly Stone, also has lupus, “and is not doing well,” the actress said. Kelly Stone has been posting videos on Instagram from her hospital bed, where she is on oxygen.

Sharon Stone has not said where her sister is hospitalized.
