What is Public Health?

If you’re wondering what is public health, then you’ve come to the right place. There are several branches of public health that you can pursue if you have the desire to help people get healthy. Listed below are some of them: Epidemiology, Biostatistics, Population and family health, Occupational medicine, and Environmental health. Listed below are the most common types of public health. To learn more about each branch, read this article.

Epidemiology

Epidemiology of public health is a discipline that studies the causes, incidence and prevalence of disease. It helps to improve health services and provide evidence for public health actions. Its main goal is to better understand the causes and preventative measures for specific diseases and populations. The field is growing rapidly, thanks in part to the Covid-19 pandemic. Epidemiology has expanded dramatically in the past decade, allowing for better public health services and responses to public health emergencies.

Biostatistics

Biostatistics in public health is the study of statistics in scientific data. This discipline combines quantitative methods with subject expertise to create rigorous studies of the literature. Biostatisticians provide the scientific community with statistical evidence that can help improve the development of public health policies and preventive health care measures. The skill set of a biostatistician is invaluable for interpreting epidemiological data and developing new methods for future studies.

Population and family health

While a primary focus of healthcare professionals is individual patient care, population and family health is increasingly important. This approach focuses on a broad range of health factors to improve the general well-being of an entire community. It also emphasizes cross-sector collaboration. For example, a population-based health approach involves examining the risks and protective factors for diseases among a particular group of individuals. The benefits of this approach include better health outcomes and lower health care costs.

Occupational medicine

Occupational medicine was developed from industrial medicine and surgery, in response to the Industrial Revolution and the introduction of social insurance. As time went on, the field expanded to include epidemiology, toxicology, hazard recognition, and environmental issues. These disciplines now focus on preventing and controlling disease and promoting the health of workers. But how can this field benefit public health? Let’s look at some of the most important factors that have influenced the practice of occupational medicine.

Disaster preparedness

Public health disaster preparedness is a critical component of any community’s response to a natural or man-made disaster. While disasters can be sudden, gradual, or long-lasting, the increased population, globalization, and environmental changes have increased their frequency and impact. While some of these disasters are preventable, such as hurricanes, many can be avoided or minimized through preparation. Below are some strategies to help your community become more prepared for disasters.

Work-related health problems

Occupational safety and health are important aspects of public and occupational health. The goal of this field is to prevent illnesses, injuries, and deaths associated with work. There are many risks associated with working, but it is also important to consider the benefits of a safe work environment. By understanding the risks and providing appropriate solutions, public health can help protect the public and the workforce. There are several benefits to addressing work-related health and safety.

Prevention of infectious diseases

Prevention of infectious diseases in public health is an important part of achieving overall health. Certain practices and policies can dramatically reduce the spread of certain infections. Some of these practices include the following:
