According to People magazine and “Today,” Tracey Dowse, the sister of the 64-year-old star, took to Instagram over the weekend to share the news.

“I am requesting support and prayers be offered me and my sister, and my only immediate family @denisedowse,” the post read. “She is currently in the hospital in a coma brought on by a virulent form of meningitis. Her doctors do not know when she will come out of the coma as it was not medically induced. She is a vibrant actor and director that should have many years ahead of her. Thoughts, prayers and support are greatly appreciated.”

No further information about her condition was immediately available.

Meningitis is “an inflammation (swelling) of the protective membranes covering the brain and spinal cord,” according to the Centers for Disease Control and Prevention.

Viral meningitis (when meningitis is caused by a virus) is the most common type of meningitis,” the agency says on its website. “Most people get better on their own without treatment. However, anyone with symptoms of meningitis should see a doctor right away because any type of meningitis can be serious. Only a doctor can determine if someone has meningitis, what is causing it, and the best treatment. Babies younger than 1 month old and people with weakened immune systems are more likely to have severe illness from viral meningitis.”

Dowse, who played Yvonne Teasley on the popular ‘90s TV series, also starred in HBO’s “Insecure” and CBS’ “The Guardian,” as well as the films “Ray,” “Pleasantville” and “Requiem for a Dream,” the news outlets reported.
