What public health risk was emphasized for hospitals after the September 11 attacks?

After the September 11 attacks, the emphasis in public health risk for hospitals shifted significantly towards the threat of weapons of mass destruction (WMD). This was due to the realization that terrorist threats could encompass not only conventional attacks but also the use of biological, chemical, and radiological agents.

Hospitals and healthcare systems needed to be prepared to respond effectively to a wide range of potential incidents involving WMD, which could cause mass casualties and require specialized medical responses. This included preparedness for treating exposure to chemical agents or biological agents that could lead to outbreaks of diseases or severe health impacts on those affected.

While infectious disease outbreaks, natural disasters, and traffic accidents are all valid public health concerns, the direct focus on weapons of mass destruction became a priority in the aftermath of the attacks. The shift led to increased funding, training, and resources directed toward emergency response capabilities specific to handling WMD threats. This demonstrated a significant change in how public health risk was perceived and addressed in the context of national security and emergency preparedness.
