The importance of Public Health


The importance of public health is undeniable, and the work of these professionals is highly respected, valued, and utilised across populations and organisations. Covid-19 has hugely increased our awareness of the role of public health professionals because those working in public health have had to learn about responding to a new disease and how to prevent it.

Healthcare experts play a particularly important role in helping to further public health efforts in a variety of ways, including research, education, medicine and vaccine distribution. Students also play an important role in public health, often contributing to research efforts while completing healthcare degree programmes.

Roles in public health

Public health professionals fulfil many roles. Sometimes, public health officials can help prevent disease outbreaks. In other cases, public health efforts can assist rural communities, implement education programmes and complete preparatory research projects. No matter the type of outreach, it contributes directly to the greater good of societies around the world.

In other words, officials in the public health sector provide advice and direction that drive health forward, reducing pressure on medical facilities and the cost of medical care to society. Public health officials also ensure they react appropriately in the face of a viral illness - especially during the current monkeypox outbreak.

Monkeypox is a viral illness that begins with flu-like symptoms and later causes a distinctive rash. Most people who contract monkeypox recover with no serious complications, but it can be a serious disease for some individuals. In May 2022, outbreaks happened in Europe, Australia, and North America. The virus that causes monkeypox is similar to the smallpox virus. This means smallpox vaccines can help prevent people from acquiring it. There is no proven treatment for monkeypox, so preventing the spread is vital for controlling outbreaks.

To do this - communication is the core of effective public health. One of the main responsibilities is to keep society apprised of the latest health developments and frequently communicate with society. Therefore, effective risk communication is crucial for enhancing understanding of health threats and to support the public in making informed decisions for mitigating the risks.
