Thyroid disorders, including thyroid dysfunction, autoimmune thyroid diseases (AITDs), and thyroid cancers (TCs), are receiving increasing attention as significant public health concerns. Viral infection can interfere with normal immune function by activating innate and adaptive immunity, causing endocrine disorders. As an important endocrine gland, thyroid function is easily affected by viral infection, inducing the formation of autoantigens by mimicking thyroid components, thereby promoting the development of AITDs. Viruses like herpes simplex virus (HSV), Epstein-Barr virus (EBV), Hepatitis C virus (HCV) and human parvovirus B19 (B19V) are potential candidates associated with AITDs. These viral infections also play a key role in tumor pathogenesis, where chronic infection or reactivation of viruses can change the immune microenvironment in the body and promote the occurrence and development of cancer. Numerous studies have confirmed the associations between various viruses, such as B19V, EBV, HSV and HCV, with TCs. This review examines the impacts of viral infections on thyroid function and the underlying mechanisms involved, and also analyzes the common characteristics and mechanisms of viral infection-induced TCs. By analyzing the existing research hypotheses, we summarized the possible mechanisms of viral infection-induced thyroid disorders and also identified the potential role of viral infection in the process of anaplastic transformation of TC. This information provides insights into the model of multistage carcinogenesis of TCs, especially the mechanism of the transition from differentiated to undifferentiated or anaplastic TCs.
