Every community is vulnerable to disaster, and every disaster presents a unique set of health hazards. Fortunately, it is possible to reduce disaster risk and improve the resilience of our communities. In Part 1 of this 2-part series, hear about the types of health risks associated with disasters and how disaster research helps to reduce the health-related impacts of disasters. In Part 2, learn what NIEHS is doing to improve researchers’ ability to collect data, track recovery, and inform future disaster preparation and response as part of a national disaster risk reduction effort.
