Harnessing nutritional immunity and advanced diagnostics for COVID-19 prevention

A B S T R A C T The ongoing worldwide health crisis caused by the COVID-19 pandemic, which began in Wuhan, China, has led to infections across the globe. Although many vaccines are available, a definitive cure has yet to be found. This study examines methods to lessen the impact of the disease, focusing on preventive actions and strengthening the immune system through diets rich in vitamins and nutrients. Our investigation also considers non-traditional methods, particularly the vital role of early detection in controlling the spread of COVID-19. Accurate diagnostic techniques are essential in this effort. Surprisingly, there is a lack of comprehensive studies on the complex interactions between various vitamins, trace metals, and immunity in relation to COVID-19. Addressing this gap, our review carefully analyzes how diets enriched with vitamin D can boost immunity. Additionally, we explore worldwide challenges that impede the progress of effective and quick diagnostic methods. Our goal is to provide a thorough understanding of the current situation regarding immunity, diagnostic procedures, and treatment approaches for COVID-19. This review not only covers various diagnostic methods for SARS-CoVs but also assesses the effectiveness of different vaccines against COVID-19. Through detailed analysis, we contribute to the ongoing discussion on fighting COVID-19, providing important information for researchers, healthcare workers, and policymakers.
