Reducing disaster risk for better health

When disasters strike, we are immediately drawn to the human suffering caused. During 2004-2013, the scale of suffering was breathtaking — more than 110,000 people died on average each year due to natural and technological hazards. Typhoon Haiyan in the Philippines, droughts in the Horn of Africa and the Ebola outbreak in West Africa are powerful examples of how emergencies not only impact people’s health, but society at large.

But much of this immediate — and post-disaster — pain, as well as the terrible structural damage inflicted on hospitals, clinics and other vital services, are avoidable through intensified government action on disaster risk management. While running health care systems is expensive, rebuilding those destroyed by disasters is many times more costly. A study from Latin America and the Caribbean over a 40-year period to 2011 estimated the damage from disasters to health infrastructure at $7.82 billion.

Disaster impacts are all the more devastating when they occur in lower-income countries. The risk of dying after a cyclone, for example, is many times greater in low-income countries compared with wealthier countries faced with cyclones of the same severity.

Why? Many factors make people in low-income countries more vulnerable to disasters. Among these is that health systems in poorer countries are often weak and that other disaster risk management capacities, such as strong early warning systems that can protect and alert populations in advance, are not in place or poorly developed.

For these reasons, and many more, the upcoming third World Conference on Disaster Risk Reduction, to be held in Sendai, Japan, is vitally important. The conference comes 10 years after governments adopted the Hyogo Framework for Action, which was a comprehensive guide to reducing disaster risk. On March 14, governments will come together again in Sendai, Japan, to adopt a new framework, in which the importance of safeguarding public health is given much more prominence.

Disasters must be considered primarily in terms of their health consequences. Impacts of disasters can be measured in lives lost or saved, people injured, as well as diseases, disabilities and psychosocial effects caused. They disrupt regular services that ensure safe mother and child health, immunize children, and provide lifesaving treatment for chronic diseases, including HIV. They often leave a lasting legacy of disease, disabilities and psychosocial effects.

These impacts can only be avoided or minimized through strong intersector collaboration to prevent, prepare for, respond to and recover from disasters, in which the health sector plays a central role. A robust health system, equipped with strong primary health care services, disease early warning systems, essential immunization programs and, importantly, risk and hazard communication campaigns, is a cornerstone of effective disaster risk management. It is also a measure of overall community well-being and resilience.

In 2013, Typhoon Haiyan swept through the Philippines, wreaking havoc, affecting 14 million people and killing more than 6,000. Many hospitals and clinics were damaged, and basic health services disrupted. This hampered the immediate response and created problems that still absorb state finances.

This is where resilience comes in. Despite Haiyan’s carnage, in the 12 months since the typhoon hit, no affected region had recorded a major disease outbreak. This in large part is due to the resilience of the Philippine’s disease surveillance system, strongly supported by the World Health Organization. Other essential public health approaches, like primary health care, immunization and safe hand-washing campaigns, not only reduce risk before disasters, but save lives when they strike.

Critical infrastructure is also central to resilience. Communities need access to safe and operational hospitals that provide the care and protection needed in disasters. Hospitals must be built to withstand local hazards, and their staff should be well-prepared to treat people when most needed. WHO will keep working with governments and partners to build on the successes that 79 countries have already had to strengthen their hospitals as a main tenet of effective disaster risk reduction.

Disasters like floods and earthquakes can also place communities at risk of disease outbreaks, especially if there is significant population displacement or disruption of utilities. Strong water and sanitation services are key to controlling diarrheal disease outbreaks. It is, therefore, critical to establish and maintain systems and measures to prevent and respond to such diseases.

An intersector, all-hazards approach to disaster risk management that engages communities is key to this goal. Many volunteers and health workers on the front lines of the Ebola response have been trained in community-based disaster risk reduction. Such volunteers can also benefit from a deeper understanding of risk reduction for other hazards, like floods and droughts.

The World Conference on Disaster Risk Reduction will help promote, and ensure, the resilience of health systems in the face of disaster risks. WHO invites all stakeholders and organizations to commit to implementing the new framework’s health aspects. WHO will also keep supporting countries to strengthen their ability to manage the risks before, during and after disasters, increase action on climate and health, and implement the International Health Regulations.

Above all, we urge all governments and stakeholders to support the implementation of the Safe Hospitals Initiative, which will make communities more resilient and protect people’s well-being and health from all types of disasters.
