Some people with Long COVID have gone on to be diagnosed with other, often post-viral diseases. Similar conditions have been seen in survivors of both Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). Unfortunately, many of these patients still show symptoms and organ damage at the 7–15-year mark.
In addition to the symptoms mentioned above, many Long COVID patients are developing additional comorbidities, seemingly triggered by the SARS-CoV-2 virus and subsequent infection. The most common conditions seen include ME/CFS, POTS, MCAS, autoimmunity, and small fiber neuropathy. It is important to address any symptoms due to these conditions as they arise.
