"The US has more than 5,600 registered healthcare facilities, the majority of which are privately owned and operated. Each varies greatly in size, location, layout, patient demographic, and resource allocation. These facilities provide patient services to millions of people each year and play a significant role at the local, state, or regional levels when responding to hazards ranging from man-made incidents, such as terrorism, to natural disasters or infectious disease outbreaks. This product provides first responders, public health officials, medical professionals, healthcare staff, and other health and medical industry partners planning and operational response considerations in advance of a potential attack at a healthcare facility."
