  During the HIV/AIDS epidemic in the US, up to 35% of those affected by TB were also infected by HIV. Handling of TB-infected patients in US hospitals was known to create airborne TB that could infect others, especially in unventilated spaces.
  
  Multiple US agencies rolled out new public health rules as a result of the TB spread: the CDC brought in new guidelines mandating HEPA filters and HEPA respirators, NIOSH pushed through new 42 CFR 84 respirator regulations in 1995 (like the N95), and OSHA created a proposed rule for TB in 1997, a result of pressure from groups like the Labor Coalition to Fight TB in the Workplace.
