Introduction: Cancer is one of the major public health problems in the world. Globally, cancer causes an estimated 9.6 million deaths every year, with over 18 million new cases recorded in 2018 alone. The traditional treatments for cancer including radiation, surgery and chemotherapy have not been enough to cure most patients or even prolong their lives. However, in recent years, immunotherapy has emerged as a potential new treatment for cancer that could finally bring hope to millions of patients worldwide. Immunotherapy is a type of treatment that uses the body's natural defenses to fight cancer. The immune system is responsible for detecting and eliminating cells that are foreign to the body, such as bacteria and viruses, as well as abnormal cells, such as cancer cells. However, cancer cells are able to evade detection by the immune system, allowing them to grow and spread throughout the body. Immunotherapy works by restoring the ability of the immune system to recognize and att...

Introduction: The world has witnessed remarkable progress in medical science, and the diseases which were once declared incurable are now curable. Diseases such as smallpox, polio, and measles that have historically caused millions of deaths are now preventable through vaccination. Currently, medical science is advancing towards treatment and prevention of a broad range of diseases. Immunotherapy is one such revolutionizing medical science field which is paving the way for the development of more effective strategies for the treatment and prevention of diseases. Immunotherapy is a cutting-edge scientific process that utilizes the body's immune system to combat various disease conditions. Unlike traditional treatments such as chemotherapy or radiation therapy that aim to kill cancerous cells, immunotherapy programs the immune system to identify and destroy the disease-causing agents. Immunotherapy has gained immense recognition in the scientific field, and its approach has the pot...

Introduction The year 2020 has been a year of unprecedented crisis caused by the COVID-19 pandemic. The outbreak has brought about unprecedented disruption across various sectors of the economy around the globe and has challenged the governments across the world to take extraordinary actions to safeguard public health and economic stability. Pandemics are rare events that have far-reaching consequences and are difficult to predict. They are disruptions to normal functioning of economic and social systems, comprising the transition of wealth and resources across societies, and their impact extends beyond the public healthcare system and patients to affect the overall economy and industry sectors. This article aims to analyze the intersection of pandemics and economies, focusing on the impact of the COVID-19 pandemic on the global economy. The research objective aims to unveil the consequences of the pandemic on various sectors, and to find possible pathways through which it could lead t...

Over the past few decades, remarkable advances in scientific technologies have revolutionized our understanding of human biology and disease. One such advance is genomics – the study of an individual's DNA sequence and how it affects their health. Genomics has immense potential in shaping the future of public health, as it can help us identify individuals at risk of developing diseases, predict the effectiveness of different treatments, and even develop personalized therapies. However, genomics also has its share of challenges, such as ethical and social implications, data privacy and security concerns, and unequal access to these technologies. The significance of genomics in public health can be illustrated by the Genomic Medicine Initiative launched by the US National Institutes of Health in 2011. This initiative aims to accelerate the discovery and application of genomic science to improve the diagnosis and treatment of various diseases. It involves developing and implementing n...

Introduction: Epidemiology is the study of the distribution and determinants of health and disease in populations. The use of epidemiology in public health has been a crucial tool for understanding disease outbreaks, controlling their spread, and providing evidence-based recommendations for policymakers and the public. In this article, we will discuss the critical role of epidemiology in our understanding and combating of disease outbreaks. Epidemiology and its functions: Epidemiology plays a vital role in public health practice and policy, providing the foundation for understanding disease outbreaks and their impact on populations. Epidemiologists use various methods to identify and describe the distribution and determinants of disease in populations. The three primary functions of epidemiology are: 1. Describing the distribution of diseases: Epidemiology involves the systematic collection, analysis, and interpretation of health-related data. Disease surveillance systems help track th...

The ongoing COVID-19 pandemic has wreaked havoc on economies around the world. Governments are struggling to balance the need to protect public health with the need to restart economic activity. The coronavirus has exposed the vulnerabilities of global supply chains, risk management processes, and trade policies. It has also challenged our social and economic systems, leaving societies struggling to navigate their way through uncharted territory. In this article, we present an effective policy for navigating the ongoing pandemic crisis that takes into account both public health and economic recovery. It offers practical solutions that can help stakeholders strike a balance between protecting public health and kick-starting economic growth. 1. Public Health Infrastructure: The first step in reopening the economy is to ensure that the public health infrastructure is robust and ready to handle any new outbreak. This includes testing, contact tracing, and timely isolation of infected indiv...
