  Recently, an infectious disease, coronavirus disease 2019 (COVID-19), has
been reported in Wuhan, China, and subsequently spread worldwide within a
couple of months. On May 16, 2020, the COVID-19 pandemic has affected several
countries in the world. In this article, we present how the amalgamation of
blockchain, cryptography, internet of medical things (IoMT), and artificial
intelligence (AI) technologies can address such an issue in the event of the
COVID-19 pandemic. Further, we propose a secure AI-based blockchain-assisted
IoMT (SAI-BA-IoMT) model for the healthcare system in the COVID-19 crisis. The
paper also examines the post-corona crisis that the world could be experienced
after the pandemic. Additionally, we exhibit the potential applications of the
proposed model to resolve the difficulties originated from coronavirus.
