A case that high doses of Vitamin C as a potential therapy for COVID-19

In December 2019, the outbreak of pneumonia caused by the novel coronavirus (SARS-CoV-2) emerged in China, representing a serious threat to public health and thus attracting worldwide attention. Recent studies revealed that the blockage of small airways by mucus plugs is considered to be an important pathophysiological change in COVID-19 patients. To date, no definite and effective treatments have been presented for COVID-19. Vitamin C is widely available and has shown the potential to inhibit airway mucus secretion, but its effect on improving the outcome of COVID-19 patients is unclear.
