The word public health undermines various factors related to the health and well-being of people living in a country, community, or any region. The existence of a top-notch health system is only possible when it caters to every individual regardless of their socioeconomic status and ensures equity. A country can only strive to do better if the government succeeds in handling healthcare concerns effectively. We might not realize it but providing healthcare for everyone comes with a cost. The higher the number of hospital visits, the higher will be the cost. Public health has expanded its focus on improving sanitation, controlling infectious diseases, gathering data, and devising strategies for future epidemics.

Public health is concerned with the health of the general population. Still, it also assures food and water safety. It provides immunizations to older adults and young children who are more prone to infectious diseases. With advancements and developments in medicine and healthcare, the challenges concerning public health have also increased. The primary objective of public health is to improve health-related quality of life and eliminate disparities existing within the healthcare system. From cleaning up the environment to using new scientific technology, public health is active on all fronts, ensuring better and enhanced healthcare system quality for everyone.

The problems that are existing today in the healthcare systems are multi-faced and require well-planned and robust solutions in the longer run. The pandemic of COVID-19 has highlighted the significance of public health multi-folds, and the healthcare system needs more public health, qualified professionals. As the advent of the online education system made it feasible, individuals with health sciences degrees now opt for online degrees. They are pursuing masters in public health online degree programs to contribute to the system. The field of public health has always been on the front while working in the background. If you are wondering how public health education can make a difference globally, here is how.

Information dependent strategies

The field of public health relies heavily on information. From assessment to policy development, or assurance, every aspect requires data to find a better solution. To cope with the COVID-19 outbreak, the public health workers and other healthcare professionals were looking for accurate data before developing a solution for the virus. There was no previously existing data to speed up the combating procedure to an unseen or novel virus strain. Still, it took a few months to assess and analyze the cases. We have finally discovered a vaccine to build immunity against the virus. It is nothing but the constant availability of information and gathering real-time data to gauge the various aspects required for making the vaccine. Informatics in public health has immense potential to improvise current health practices and transform the present-day capacity in the healthcare systems.

Effective surveillance

Public health undermines various fields like biostatistics, immunization, monitoring, and other aspects essential for developing better public health policies. Diseases can occur anytime with varied causes. A single visit to a hospital enables us to identify the cause and treatment for a particular ailment. The word surveillance in public health extends beyond the assessment of causes and spread of diseases. It also entails the evaluation of living conditions and their impact on the health of an individual. Qualified public health workers can make a difference by analyzing the living conditions of people living in rural areas and focus on the solutions to alleviate their situation. Surveillance also plays a significant role in tracking the accessibility of people to the healthcare facility and resources.

Public awareness

Improving the health conditions of people requires collective efforts on every level. It requires contribution from the government in the form of policies, but it also requires input from the people. Indeed, public health surrounds the health and well-being of the general population. Still, it can only prove to be effective if people are aware of what they are doing. For instance, during the COVID-19 outbreak, the healthcare professional found preventative measures to stop its spread through specific protocols. The decrease in the cases and improvement in the recovery surge became possible when people started to contribute towards its prevention. It is inevitable and desirable to promote health and disease prevention using every conceivable media, whether digital or electronic. Public awareness plays a substantial role in assisting healthcare professionals and public health workers in advancing towards the next step in finding the cure once the spread is under control.

Educating the public health workforce

It is one of the critical challenges for public health informatics to educate the public health workforce regarding the technology involved in public health activities. The modern developments in the field of medicine have introduced different techniques and methodologies that require training. Ensuring some informatics training for new and existing public health workers is essential to boost their performance and enhance its functionality. Every public health worker must have basic knowledge of epidemiology. Similarly, having basic knowledge of informatics will help in effective practice in this information technology era.


The role of public health in every citizen’s life has become increasingly prominent, and the gaps in the training of public health professionals. One of the crucial gaps that exist concerns skill-based performance and practice in communication. Communication plays a vital role in building the foundation for the collective efforts required by public health professionals. Providing training to the individuals in understanding communication in delivering a particular message to a non-specialist is crucial in improving healthcare situations and spreading awareness. Risk communication is also essential in addressing the adverse event or the potential hazards arising from a recent epidemic threatening public safety.


Health and well-being are one of the main motives of every country as healthy citizens contribute more to running the systems and economy of a country. Public health focuses on alleviating the situations to improve the quality of life and longevity of individuals. From public awareness to building immunity in the general population, every step has a global impact. Public health education contributes to every aspect of human lives.
