The Centers for Disease Control said a humidifier that was not used for a decade is connected to deadly cases of Aspergillus mold infections at Seattle Children's, according to an article on the King5 website.
The hospital humidifier was not turned on for more than a decade. Then, the humidifier was switched on in 2018 and again in 2019.
Aspergillus mold infected at least 14 patients since 2001 and killed six of them.
Children's said last year that it believed Aspergillus mold was flowing through the ventilation system in some of its operating rooms.
