Undoubtedly, public health issues are of utmost importance since they affect the well-being of the entire population. In 2023, the world faces many public health challenges that demand our attention and action. From infectious diseases to mental health and chronic diseases, the burden of illness continues to weigh heavily on communities worldwide. According to the World Health Organization, an estimated 300 million people suffer from depression globally. The Covid pandemic has further increased mental health challenges.. Environmental health issues like air pollution and climate change continue to impact human health and natural landscapes.

Additionally, social determinants of health, such as poverty and discrimination, play a critical role in shaping health outcomes. We must address these pressing public health issues to create a healthier and more equitable world. The article explores the public health issues most likely to hit in 2023.

Infectious diseases

Public health is a critical aspect of our daily lives, and infectious diseases remain a pressing concern. Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, and fungi. They can spread easily from person to person through contact, air, or water. In 2023, the world continues to grapple with the Covid pandemic, which has caused significant morbidity and mortality globally. New flu strains continue to emerge, and the threat of pandemics remains a looming concern.

Like any other part of the continent, cases of infectious diseases are reported in California too. The most common infectious diseases in South California include tuberculosis, meningitis, and sexually transmitted infections. The spread of these diseases can be mitigated by practising good hygiene, getting vaccinated, and seeking medical attention promptly. In this context, MPH online programmes play a pivotal role. These programs prepare public health professionals to tackle these issues and equip them with the necessary skills to develop and implement effective strategies. 

Mental health

In 2023, mental health has become a crucial public health issue affecting millions worldwide. According to the World Health Organization, depression is now the leading cause of disability worldwide. There are an estimated 322 million people affected globally. Anxiety disorders also remain prevalent, affecting approximately 264 million people globally. PTSD, a mental health condition caused by exposure to traumatic events, continues to impact millions globally. In fact, in the United States alone, approximately 7%–8% of the population will experience PTSD at some point.

The importance of mental health cannot be overstated. Good mental health is essential for overall well-being and is critical for individuals to lead productive and fulfilling lives. Mental health issues can cause various problems, including impaired social functioning, decreased quality of life, and suicide. With the rise of the Covid pandemic, mental health issues have become even more prevalent. Stress, anxiety, and depression affect many people worldwide.

As we move forward in 2023, we must prioritize mental health and provide support and resources to those in need. By increasing awareness, reducing stigma, and improving access to mental health care, we can work towards a brighter and healthier future for all.

Chronic diseases

Chronic diseases are long-term health conditions that are typically progressive and incurable. Various factors, including genetics, lifestyle choices, and environmental factors, cause them. Unfortunately, chronic diseases have become a major global health challenge in 2023.  Chronic diseases, including heart disease, cancer, and diabetes, are responsible for 74% of all deaths worldwide. Heart disease remains the leading cause of death worldwide. It claims over 17.9 million lives yearly, followed closely by cancer, responsible for more than 10 million deaths annually. Diabetes, another prevalent chronic disease, has become a global epidemic affecting 422 million people worldwide.

These staggering statistics paint a grim picture of chronic diseases in 2023. However, there is hope for the future. With increased public awareness and access to healthcare, many chronic diseases can be prevented, managed, or even cured. By adopting healthy lifestyle choices, individuals can significantly reduce their risk of developing chronic diseases. Additionally, early detection and treatment can improve chronic disease management outcomes.

Environmental health

The state of our environment in 2023 profoundly impacts public health. Air pollution, for example, is a leading cause of respiratory illness, with an estimated 7 million premature deaths annually worldwide. In addition, water pollution is responsible for causing diarrheal diseases that kill approximately 485,000 people annually. Climate change has also become a significant health threat, leading to more frequent and intense natural disasters, extreme weather conditions, and increased rates of infectious diseases. According to the World Health Organization, climate change will cause an additional 250,000 deaths annually between 2030 and 2050.

The need to address these environmental health issues has become more urgent than ever before. In 2023, governments and individuals will recognize the importance of implementing sustainable practices and reducing our carbon footprint. From transitioning to renewable energy sources to reducing plastic waste, there are many steps we can take to protect the environment and improve public health. 

Social determinants of health

In 2023, the impact of social factors on public health has become more evident than ever. Studies show that poverty, discrimination, and limited access to healthcare continue to be significant barriers to good health. For instance, poverty is a leading social determinant of health.

Discrimination against marginalised groups remains a pervasive issue, with racial and ethnic minorities experiencing higher rates of chronic diseases and mortality than their white counterparts. Access to healthcare is also a critical social determinant of health. Approximately 400 million people lack access to essential health services globally. These social determinants of health create health inequities that persist across generations, affecting individuals’ and communities’ physical, mental, and social well-being. Addressing these issues will require concerted efforts from individuals, communities, and governments, including policy changes prioritizing health equity, investments in social programs, and targeted interventions to improve access to healthcare for all.


Looking back on the top public health issues prevalent in the past while stepping into the year 2023, we are reminded of their significant impact on our society. Both individuals and governments must take action to address these pressing concerns.

We must work together to promote healthy lifestyles, increase access to healthcare, and advocate for policies prioritizing public health. Although these challenges may seem daunting, there is hope for positive change. With advancements in technology and medicine and a growing awareness of the importance of public health, we can make a significant impact in the future.
