At the Autoimmune Registry, we publish a list of over 100 confirmed and suspected autoimmune diseases. While scientists don't yet fully understand the mechanism behind long Covid, many suspect it to be autoimmune. By listing long Covid as an unconfirmed autoimmune disease, we aim to collect data on

The Autoimmune Registry has determined that biomarkers of immune system activity similar to those seen in many autoimmune and autoinflammatory diseases justify the inclusion of Long COVID on its list of diseases.

High levels of antibodies to the immune-system proteins called type I interferons (IFNs) have been associated with severe COVID-19.   Other studies have shown that severely ill patients tend to have a high concentration of pro-inflammatory cytokines, such as interleukin (IL)-6, compared to those who are moderately ill.

The Autoimmune Registry has decided to include Long COVID in its list of autoimmune diseases to support research into this emerging chronic condition.
