The World Trade Center Health Program provides nationwide medical monitoring, treatment, care, and medications for anyone sickened by the 9/11 terrorist attacks and the toxic dust. The WTC Health Program provides benefits to first responders, recovery, and cleanup workers, and volunteers who helped after the terrorist attacks on September 11, 2001, at Ground Zero, the Pentagon, and the crash site near Shanksville, Pennsylvania.

The WTC Health Program also provides the same health benefits and treatment for eligible people who worked, lived, or attended school, or were in childcare in lower Manhattan and parts of downtown Brooklyn at any time during the 9/11 attacks or at any time during the eight-and-a-half months after the attacks.
