90210 star Denise Dowse in a coma as actor's sister shares emotional post

Beverly Hills, 90210 star Denise Dowse is in a coma in hospital.

Denise's sister, Tracey, said the actress, 64, is battling a 'virulent form of meningitis' and took to social media to explain to followers what's been happening.

"As many of you have seen, my posts have been positive and up lifting. I am trying to keep my spirits up and support those who need it. As many of you know I am a private person. So this is hard for me," the statement read.

"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. 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. 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."

Following the post, friends and followers rushed to the comments to offer their support.

Beverly Hills, 90210 co-star Ian Ziering wrote: "Sending prayers and hopes for better days ahead."

While Stephen Howard added: "Sending love, prayer and hugs to one of my favourites."

And another added: "Oh my gosh! I am so sorry to hear this!! Denise is a strong, grounded, & beautiful artist & human!!! Sending love & light that she will pull through this stronger than ever!"

The NHS explains that meningitis is an infection of the protective membranes that surround the brain and spinal cord. It can be very serious if not treated quickly and can cause life-threatening blood poisoning (septicaemia) and result in permanent damage to the brain or nerves.

Denise had a recurring role in Beverly Hills, 90210, where she played Vice Principal Yvonne Teasley. She later went on to star in California Dreams as well as appearing in Seinfield, Full House, Murphy Brown, Step by Step, Sister, Sister, Moesha, Girlfriends and Insecure.

Meanwhile, Denise's directorial debut, Remember Me: The Mahalia Jackson Story, is currently in post-production.

We're wishing Denise a speedy recovery.
