When Dowse's sister Tracey revealed the state of the actress' health on Tuesday, she wrote on Dowse's Instagram page: "I am requesting support and prayers be offered me and my sister, and my only immediate family @denisedowse."

"She is currently in the hospital in a coma brought on by a virulent form of meningitis," Tracey continued. "Her doctors do not know when she will come out of the coma as it was not medically induced."

Dowse's sibling added: "She is a vibrant actor and director that should have many years ahead of her. Thoughts, prayers and support are greatly appreciated. I have been reading your comments and want to acknowledge everyone's comments. I will not be responding to your texts as I do not want you to think it is coming from her at this time."
