World Health Organization

Hello! We are the World Health Organization, but many people know us by our acronym, WHO. Our story begins on April 7th, 1948, a few years after a big, global war had ended. At that time, leaders from countries all over the world came together to form the United Nations, a group dedicated to keeping peace. We were created as a special part of the United Nations because these leaders understood a very important idea: for the world to be peaceful, its people must be healthy. They believed that good health is a fundamental right for every single person, not a special privilege for only a few. From that day forward, our main goal has been to help all people, everywhere in the world, live the healthiest lives possible.

One of our most important and well-known jobs has been leading the fight against powerful diseases that have affected humanity for centuries. For a very long time, a disease called smallpox was a major threat. It caused serious illness and was feared all around the globe. To fight it, we knew that no single country could succeed alone. So, we led a massive global team. This team included thousands of dedicated doctors, nurses, and health workers from many different nations who traveled to cities, towns, and remote villages to give people vaccinations. A vaccination is a special shot that teaches a person's body how to fight off a disease so they don't get sick.

This global effort to vaccinate everyone against smallpox took many years of patient and difficult work. Finally, after this incredible worldwide cooperation, we were able to make a historic announcement. In 1980, we declared that smallpox was officially gone from the world—it had been completely eradicated! This was a tremendous victory for all of humanity. It was the first time in history that people had worked together to completely wipe out a disease. This success proved that when the world unites for a common goal, we can achieve amazing things. It gave us hope and a clear plan for how to take on other major health challenges.

We use the valuable lessons we learned from the fight against smallpox in our work every day. That victory became a blueprint for tackling other dangerous diseases. For example, we are part of a global effort to eradicate another disease called polio, which can harm children. Through large-scale vaccination campaigns similar to the one for smallpox, polio has now been eliminated from most parts of the world. We also work to control diseases like malaria, which is spread by mosquitoes. Our work on these illnesses shows how a success from the past can continue to guide our mission to protect people in the present.

Today, our work has expanded to include many different ways of keeping the world healthy and safe. A big part of our job is to act as the world's health lookout. We have experts who constantly watch for outbreaks of new or dangerous diseases. When we spot a threat, we can quickly warn countries and provide the scientific guidance they need to prepare and respond. This work is essential for preventing a local health problem from becoming a global emergency, like a pandemic. We help countries strengthen their hospitals and train their health workers so they are ready for any crisis.

We also help make the world healthier by setting global rules and standards. Think of it like a rulebook for health that every country can follow. For example, we create guidelines to ensure that medicines are made safely and work correctly, no matter where in the world you are. We do the same for food, helping to make sure it is safe to eat. These global standards also apply to the world around us. We share scientific information about what makes for clean water and safe air, because we know that a healthy environment is one of the most important ingredients for a healthy life.

Sharing knowledge is at the heart of what we do. We bring together the world’s top scientists and health experts to study health problems and find the best solutions. We then share this information with governments and doctors everywhere. This helps them make the best possible decisions to protect the people they serve. Our guidance covers a wide range of topics, from how to stop the spread of a virus to the best ways to help mothers and babies stay healthy during and after childbirth. By making sure everyone has access to reliable, science-based information, we help raise the level of health for all.

Our mission continues every single day, because new health challenges are always appearing. To do our work, we have offices all around the globe. This allows us to work closely with local communities and their leaders to understand their unique needs and support them directly. Our ultimate dream is simple to say but a great challenge to achieve: 'Health for All.' This guiding principle means we never stop working to build a safer, healthier future for every child, every adult, and every family, no matter who they are or where they live. We believe that by working together, we can help make the world a better, healthier place for everyone.
