ME Diagnosis: Delay Harms Health
Around 75% of people with ME/CFS describe a sudden onset to their illness, often dating back to an acute viral infection. This could be an episode of bronchitis, gastroenteritis, tonsillitis, or viral meningitis. Sometimes it is a more specific infection such as chickenpox, glandular fever, or rubella. ME/CFS occasionally occurs following other types of infection such as mycoplasma, Q fever, salmonella or toxoplasmosis. Instances have also been reported where ME/CFS has been triggered by a vaccination, or exposure to toxins or pesticides.
