Identify movie about an alien disease that turns people to stone

Question

Please help me identity this movie. Here are the details I remember.

• I watched this in early 2000’s as an adolescent.
• Scene of suburban U.S. where a female alien teleports into the town via portal on the street. Humans are familiar with this alien. She apparently is sick with a disease.
• The humans follow the alien to *wherever they go - very rocky, undeveloped terrain.
• The humans somehow contract the disease, possibly by touch.
• The disease makes them turn into a strange stone, and become part of the stone landscape of the alien world.
• Their skin looks like coral reef, or maybe with holes that would bother people with trypophobia.
• The people have a good relationship with the alien suffering from the disease, so turning into stone is emotional and sad.

This may have been a twilight zone, x files, or fringe type show, or a movie. I was quite disturbed by it as a child and now I would like to revisit those memories.

Answer 1

Not an exact match to all the details you listed, but much of it lines up with the Outer Limits (1995) episode "Feasibility Study" which is a re-make of the similarly-titled episode from the "original series". A comment compares the plot points you listed with the original series episode. The only details that don't line up with the episode I identified pertain to "female alien teleports" and "humans are familiar with this alien".

In the 1997 version of Feasibility Study, an entire suburban community is scooped up by aliens to determine whether humans would make suitable slaves, but the effort is complicated by a contagious pathogen which turns its victims into something stone-like. A young woman (played by Laura Harris) is led through a barrier separating the Earth-like environment from what looks like a wasteland, meeting an alien. The young woman's father subsequently finds his way through the barrier also, and encounters the aliens in charge of the operation who boastfully reveal their intentions.
