摘　　要：The dynamics of COVID-19 and mucormycosis reveal a complex interplay of genetic factors that influence the susceptibility,severity,and immune responses.COVID-19,caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),exhibits an increased incidence of mucormycosis,particularly in individuals with comorbidities or corticosteroid therapy.Mucormycosis is a fungal infection that affects the sinuses,orbits,and lungs and demands timely intervention with antifungal medications and surgery because of its life-threatening nature.Research on the genetic underpinnings of this intersection has unveiled key insights into the pathogenicity of Mucorales.Breakthroughs in genetic tools have exposed virulence factors,such as the CotH protein family and high-affinity iron-uptake mechanisms.Genetic susceptibility is a pivotal element in identifying individuals at risk of developing COVID-19,facilitating early detection,and allowing for personalized treatment strategies.DPP9,MIF,and TYK2 are among the genes implicated in COVID-19 severity,emphasizing the intricate relationship between genetic makeup and viral response.The genetic landscape extends to viral entry mechanisms,thereby affecting infection efficiency.Specific polymorphisms in genes such as IFNAR2,OAS3,and TYK2 are associated with COVID-19 severity,indicating shared genetic bases between severe and hospitalized cases.Mucormycosis is genetically predisposed,particularly in immunocompromised individuals.The challenge lies in understanding the genetic factors influencing susceptibility and offering insights into pathogenesis and potential therapeutic avenues.Organ transplantation adds another layer,increasing susceptibility to infections such as COVID-19 and mucormycosis.The impact of immunosuppression on COVID-19 severity remains elusive,necessitating ongoing research on the immunological mechanisms.Despite the challenges posed by emerging SARSCoV-2 variants,the intricate connection between genetic factors and the interplay of COVID-19 and mucormycosis presents
