Authorities have quarantined a home near Houston, Texas, featured in the show ''Hoarding: Buried Alive.'' A worker who helped clean that house has now come down with hantavirus.
As many as 30 crew members were in the home over a two-week period.
Hantavirus is fatal up to half the time.
The infected woman is now recovering.
"Hantavirus is a disease which is spread by rodents. And when you go through processes like cleaning the home, sweeping, vacuuming, these sorts of things, it goes into the air. When it goes into the air, it's breathed in, and it affects the lungs," said dr Mark Escott, medical director, Montgomery County, Texas.
This latest infection comes after three visitors to Yosemite National Park in California died from hantavirus after staying in cabins infected with the disease.
