The novel COVID-19 variant NB.1.8.1 has been classified as a Variant Under Monitoring (VUM) by the World Health Organization, signaling the continued evolution of the pandemic in 2025. This designation highlights the potential impact of ongoing viral mutations on global public health. This review provides a comprehensive overview of the current epidemiological landscape, highlighting key trends, diagnostic innovations, emerging health concerns, and strategic approaches for disease management in the current phase of the pandemic. By June 2025, global test positivity rates have risen to 11%, with India reporting an increase in active COVID-19 cases, reaching 4,866. These indicators point to a resurgence that warrants renewed attention to containment and treatment strategies. In this context, the role of evidence-based nutrition and dietary support has become increasingly significant. Recent findings underscore the importance of targeted nutritional interventions and supplementation in bolstering immune function, reducing symptom severity, and aiding recovery from COVID-19. This article synthesizes the latest scientific evidence on dietary protocols, focusing on key nutrients such as vitamin D, zinc, and omega-3 fatty acids, alongside other bioactive compounds known to enhance immune resilience. It also explores personalized nutrition strategies tailored to individual risk profiles and comorbidities, reflecting a growing trend toward integrative and preventive healthcare. Through an analysis of current data and clinical recommendations, this review aims to support healthcare professionals, researchers, and policymakers in refining COVID-19 response strategies. Emphasizing the intersection of nutrition and infectious disease management, it highlights how dietary science can serve as a vital adjunct to medical treatment in navigating the ongoing challenges of the pandemic.
