The world is facing a global crisis and health emergency of COVID-19. Understanding of COVID-19 pathophysiology in ayurvedic host centric framework is prerequisite for apt use of Ayurveda. This paper reviews COVID-19 pathophysiology, clinical presentations and prognosis in ayurvedic perspective. Concept of exogenous pathogenic diseases can be traced in fever, microbes, toxins, epidemics and seasonal regimens chapters of Ayurveda. Such exogenous diseases later manifest multi-system presentation according to involvement of different ‘Dosha’ and derangement of ‘Agni’. The pathology of COVID-19 is primarily that of Sannipata Jwara (fever) with involvement of respiratory system. Secondary manifestations include coagulopathies, cardiovascular, neural, and renal complications. Gastrointestinal system is closely associated with respiratory mechanism in ayurvedic pathophysiological conceptualization of Srotas. Abnormal immune responses in COVID-19 are result of abnormalities of Tridosha, Rakta (blood) and Ojus (Vital nectar). The initial phase is VataKapha dominant whereas later stage of aggravated immune response is Vata-Pitta dominant. Alveolar damage, coagulopathies indicate Rakta dhatu vitiation. This integrative understanding of COVID-19, we can propose novel strategies for therapeutics and prophylaxis. Measures for ‘Conservation of Agni-bala’, ‘Attainment of Rakta- Pitta-Prana homeostasis and ‘Protection of Tri-Marma i.e. vital organs’ can be important Host based strategies for reduction in the mortality in COVID-19 and for better clinical outcomes. This host centric approach can make paradigm shift in management of this epidemic.
