Hurricane Katrina made landfall near New Orleans, Louisiana on 29 August 2005, with sustained wind speeds of approximately 200 km/h. Katrina submerged 80% of the city under water. The U.S. Department of Health and Human Services quickly declared a public health emergency. The Federal Emergency Management Agency (FEMA) declared an area roughly equivalent to the size of the United Kingdom as a disaster area.


The Pan American Health Organization/World Health Organization; collaborated with the U.S. Department of Health and Human Services (HHS) at the federal and state levels and with the Centers for Disease Control (CDC), providing technical collaboration in a number of public health areas.

Almost four weeks later, Hurricane Rita dealt another devastating blow to the same area, causing flooding to reoccur in New Orleans and other low-lying areas of the state of Louisiana. This time, however, the state of Texas suffered the direct brunt of the storm. The fact that several million people chose to heed evacuation warnings may have contributed to the reduced death toll.

As the emergency response phase gradually transitions into recovery and rehabilitation and as emergency lifesaving activities slowly wind down, other areas of public health emerge as important concerns:


Safe Hospitals: an important opportunity is at hand to rebuild these critical facilities, incorporating disaster mitigation measures to reduce their vulnerability to the avoidable consequences of disasters. Read more.


Mental Health: Given the many pressing public health concerns in the aftermath of disasters, mental health care for disaster victims can be overlooked early on. Read more about mental health services and stress management.


International Aid: The arrival of aid from outside an affected area can pose a serious challenge, particularly if it has not been requested, is inappropriate for the situation or diverts personnel from other more pressing tasks. Read more about this issue.
