On May 21, 2007, OSHA issued a pandemic flu preparedness guidance for health care workers and employers. This new guidance focuses specifically on health care workers and their employers. It is consistent with all previous pandemic preparedness guidance issued by OSHA, the Centers for Disease Control and Prevention, and Department of Health and Human Services, the agency said. The 104-page document addresses flu diagnosis and treatment, infection control, health care worker vaccination, personal protective equipment, preparedness planning, and OSHA standards.
