The city of Houston spent more than a million dollars on counterfeit masks, according to court documents.

(CNN) – Ten Covid-19 unit nurses are heading back to work after being placed on paid administrative leave for refusing to enter coronavirus patient rooms without an N95 mask. "They said it would stay in our file for three months and then they will take it out," Cline told CNN. Before that, the hospital had said there were no N95 masks for them and insisted they wear surgical masks instead, the nurses said​, even though other health care workers at the hospital were provided N95 masks. Cline and Michael Gulick, another nurse put on leave, previously told CNN the hospital would give them surgical masks -- not N95 masks -- while they were treating Covid-19 patients on April 9. Although the N95 masks are preferred, health care workers should only wear other face masks, such as surgical masks, when respirators are not available.
