‘Real Housewives of Dallas’ star D’Andra Simmons is bedridden in a hospital due to COVID-19 — the first cast member from the Bravo shows who’s gotten this ill.

Simmons’ condition was first announced by podcast host Kate Casey, who says … “Just heard from D’Andra and she is asking for your prayers. She’s in the hospital and struggling.”

A rep for D’Andra has confirmed she’s in bad shape.

The rep says D’Andra’s been admitted into the COVID ward at UT Southwestern Hospital. It’s unclear when she contracted the virus, or how long she’s been at the hospital … but her team says her oxygen levels have been borderline, and she’s starting Remdesivir.

That’s one of the anti-viral drugs President Trump was given when he came down with COVID — part of the cocktail of therapeutics he says helped him recover quickly.

Simmons’ diagnosis and health status is noteworthy — as she appears to be the only ‘Real Housewife’ who’s had to get checked in and treated for coronavirus. Others have had it — including ‘RHOBH’ stars Kyle Richards, Kathy Hilton and Dorit Kemsley, but none required hospitalization.

As we’ve reported … Bravo production crews have taken several steps to help keep the different ‘Housewives’ sets as safe as possible. They’re requiring masks on everyone who isn’t on-camera, they’re doing temp checks, they’re mostly shooting outdoors … and everyone’s encouraged to spread out. Still, despite that, some stars and others on set have caught it.
