"Insecure" actress Denise Dowse sparked worries as she faces a dreaded disease.

Dowse's sister, Tracey Dowse, delivered the tragic news in a Facebook post on August 5 (via Deadline), confirming the actress's current condition. She revealed that the "Grey's Anatomy" actress remains in a hospital and in a coma after contracting meningitis.

"I am requesting support and prayers be offered to me and my sister, and my only immediate family Denise Dowse. 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," Tracey disclosed.

The sister called the actress a "vibrant actor and director" who still has a brighter future ahead. With that, she and the whole family are asking everyone to pray for her.

Tracey confirmed the same news to a news outlet, saying that Dowse remains in a coma. The actress's doctors also do not know when she would come out of it since it was not medically induced.

Per Neurology.org, bacterial meningitis causes a decreased level of consciousness.

"Many patients with bacterial meningitis present with an abnormal conscious state, and 15%-20% of patients are comatose upon presentation.5 An abnormal conscious state, in most studies graded by the Glasgow Coma Scale, is a strong predictor for poor disease outcome in bacterial meningitis," it explains.

Meanwhile, the Centers for Disease Control and Prevention says that the swelling in patients with meningitis is typically caused by a bacterial or viral infection of the fluid that surrounds the brain and spinal cord.

Amid her health battle, her fans and colleagues shared their prayers online as they continue to hope for her recovery.

One said, "Just heard the news. Keeping my friend @denisedowse in my prayers."
