Thyroiditis is generally not contagious. Thyroiditis is a group of diseases caused by destruction of thyroid follicular tissue due to pathogenic infections, autoimmune deficiencies, and other factors, resulting in localized symptoms of the thyroid gland and abnormal levels of thyroid hormones, and is commonly seen in Hashimoto’s thyroiditis, subacute thyroiditis, and so on. There is no infectious agent involved in the pathogenesis, so it is generally not contagious.
Hashimoto’s thyroiditis is an autoimmune-related thyroiditis, in which the autoimmune system produces an immune response to thyroglobulin and thyroid peroxidase in the thyroid gland, causing diffuse lesions in the thyroid gland, which are often positive for thyroid autoantibodies in blood tests. This disease is caused by an autoimmune deficiency and is not contagious without the involvement of infectious pathogens.
Subacute thyroiditis, on the other hand, is a viral infection-related inflammation of the thyroid gland, the pathology of which is granulomatous thyroiditis, a self-limiting disease that usually manifests itself as pain and fever in the thyroid area, and is also not contagious.
Thyroiditis patients should go to the hospital in time, after a clear diagnosis under the guidance of the doctor for standardized treatment.
