Nutrition amid the COVID-19 pandemic: a multi-level framework for action

COVID-19, a disease caused by a novel coronavirus, became a major global human threat that has turned into a pandemic. Coronavirus is one of the major pathogens that mainly targets the human respiratory system. In late December 2019, a cluster of patients were admitted to hospitals with an initial diagnosis of pneumonia of an unknown etiology [1]. Early reports predicted the onset of a possible coronavirus outbreak called SARS-CoV-2, causing the disease COVID-19. The ongoing epidemic has been declared by the World Health Organization (WHO) as a global public health emergency [2].
