The relationship between thyroid hormone and immunological regulation has been widely studied in physiological and pathological contexts.3 However, evidence is required to emphasise the relationship between thyroid hormone and COVID-19 disease progression since immune system regulation affects how rapidly patients with COVID-19 develop the disease.8 Evidence related to how thyroid disorders affect the course of COVID-19 infection and disease is scarce. The gene discussed is TG; the disease is thyroid gland disorder.
