Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), most commonly referred to as COVID-19, is an acute infectious respiratory disease that has led to a global pandemic. While vaccination rollouts have begun, there is currently no effective cure for COVID-19. However, multiple factor treatment of the virus has been proven to be most efficient at slowing the rate of reproduction and spread of the virus as well as improving immune response once infected. Therefore, exploring the role that diet plays in both general immune function and specifically with SARS-CoV-2 may lead to better health outcomes globally. In addition, the role that national lockdowns have had in lifestyle changes will be discussed, and how these shifts may exacerbate the morbidity and mortality of COVID-19.
