The Role of Public Health Workers in Disaster Situations


According to Statista, 97 natural disasters occurred in the US in 2021. These were a mix of floods, storms, and fires. Besides destroying property and the environment, natural disasters can also severely impact public health. 

This is especially true for people living in disaster-prone areas, who are particularly to diseases, injuries, and mental health issues. This overwhelming toll has put a spotlight on the role of public health workers in disaster situations.

Public health workers are the first responders who provide lifesaving aid and support to the people in need. They have the knowledge and skills to assess, prevent, and manage public health emergencies.

If you're considering a career in public health, you should know that it is an incredibly rewarding profession. Let's look at how public health workers are the heroes of disaster situations:

What Do Public Healths Workers Do?

Public health workers are responsible for helping communities prepare and respond to emergencies. Their duty begins before the disaster occurs, as they work to develop preparedness plans and provide education to the public. 

They're also responsible for coordinating relief teams and providing medical care during an emergency. After a disaster, they work to assess the health impacts and assist with community recovery efforts.

Pre Requisites to Becoming a Public Health Worker

Public health workers are usually required to hold a bachelor's degree in public health, health sciences, or a related field. It is also important for them to have experience working with communities, conducting public health research, or providing medical care.

But for professionals interested in excelling in public health, an MPH (Master of Public Health) degree is usually the ideal choice. MPH programs are designed to equip students with advanced skills to succeed in public health. 

An MPH online no GRE required program is quite popular, as it offers a convenient way to earn an MPH without taking standardized tests.

The Role of Public Health Workers in Emergencies

1. Risk Assessment:

While natural disasters kill about 60,000 people worldwide each year, they also result in property damage and disrupted livelihoods. But risk assessment, planning, and forecasting can minimize these risks. That's where public health workers step in.

They use various methods to identify potential health hazards, such as:

  • Analyzing data on disease trends
  • Monitoring environmental factors that can affect health
  • Conducting community health assessments

This assessment involves identifying the likelihood and severity of a particular health risk and its potential impact on the community.

Public health workers also consider the demographics and specific needs of the community when assessing risks. For instance, they may focus on the elderly, pregnant women, or children who are particularly vulnerable to the effects of a natural disaster.

2. Disaster Preparedness

Public health workers collect information during the risk assessment stage changes how a community prepares for and responds to natural disasters. It is now more aware of the potential health risks and can take steps to mitigate them.

Disaster preparedness involves a comprehensive approach that includes early warning systems and emergency response planning. Based on the risk assessment, public health workers develop emergency response plans. 

These outline the roles and responsibilities of emergency responders, communication protocols, and evacuation procedures. For instance, they might need to identify evacuation routes, ensure food and water supplies are available in emergency shelters, or organize special assistance for people with disabilities.

3. Response Planning

Of course, no amount of preparation can protect a community from the effects of an emergency. That's why public health workers play such an important role during and after disasters.

Public health workers coordinate relief teams and provide medical care to those affected by an emergency. It involves assessing the community's needs and providing food, shelter, sanitation, and medical care assistance.

They also provide emotional support to people affected by the disaster and support long-term recovery efforts. Furthermore, early warning systems are implemented to alert local populations about impending disasters and ensure efficient evacuation.

4. Coordinate with Governments

Protecting the communities from the harsh effects of natural disasters requires seamless coordination among all stakeholders. It isn't a one-man show. Public health workers coordinate with governments, non-governmental organizations, and other emergency responders to ensure an efficient response.

They also play a critical role in developing policies and legislation related to disaster management. For instance, they might need to advise government agencies on how best to allocate resources or develop regulations related to an emergency evacuation.

Since public health workers have the knowledge and skills to assess health risks, their intervention in developing strategies ensures that the government takes appropriate and effective measures.

5. Educating the Community

Public health workers also play a key role in educating people about natural disasters and how to protect themselves. Unless the community is aware of the risks they face and knows how to defend themselves, precious lives will be lost.

And so, public health workers provide education and training on preparing for disasters, recognizing potential health hazards, and responding appropriately. They also work with local organizations or school boards to develop fact sheets, workshops, and other materials to help educate the public.

Some of the most promising public health worker intervention results come from programs that teach communities how to create their own plans for responding to disasters. It allows them to take ownership of the process and become more resilient during emergencies.

6. Recovery After the Disaster

Once the initial emergency phase ends, it's time to start rebuilding. Where will people live? What will they eat? How will they earn money? These are questions that public health workers must answer.

They guide relief organizations and support efforts to rebuild the community. It may include providing medical and mental health services, improving water and sanitation facilities, or restoring livelihoods.

It is a complex process that requires the commitment of many different stakeholders. But, with the help of public health workers, communities can recover from disasters and start to rebuild their lives.


It is clear that public health workers play an invaluable role in preparing for and responding to natural disasters. They are the eyes, ears, and brains of the relief effort. 

Their knowledge and experience provide valuable insight that can save lives and help communities recover more quickly. Without them, the impact of natural disasters would be much more severe. 

Therefore, it is important to recognize and appreciate the work of public health workers in times of disaster. They are a vital part of keeping communities safe and healthy.

If you're considering a career in public health, don't hesitate. You will be making an invaluable contribution to society and helping people in need during their time of greatest vulnerability.
