Doctors Begin to Crack Covid’s Mysterious Long-Term Effects
Wall Street Journal Nov1, PDF
- “Other viral outbreaks, including the original SARS, MERS, Ebola, H1N1 and the Spanish flu, have been associated with long-term symptoms. Scientists reported that some patients experienced fatigue, sleep problems and joint and muscle pain long after their bodies cleared a virus, according to a recent review chronicling the long-term effects of viral infections.
- “Some of the most compelling evidence for the inflammation theory comes from Covid-19 patients with signs of heart inflammation and injury months after illness. One study looking at 100 Covid-19 patients two months after getting sick found that 78 had abnormal findings on cardiac magnetic resonance imaging, while 60 had cardiac MRIs indicating heart-muscle inflammation. The study included hospitalized, nonhospitalized and asymptomatic patients.”
- “Another possibility is that the virus causes some people’s immune systems to attack and damage their own organs and tissues, researchers said. A June study found roughly half of 29 hospitalized ICU patients with Covid-19 had one or more types of autoantibodies—antibodies that mistakenly target and attack a patient’s own tissues or organs.”
- Of the Long haul COVID-19 patients…” About 90% of such patients report having symptoms of exercise intolerance, fatigue and elevated heartbeats. About 40% to 50% also report symptoms such as gastrointestinal issues, headaches and shortness of breath."
- “. A 2009 study of 233 SARS survivors found 27% met criteria for chronic fatigue syndrome four years after getting sick.”

- "Our results show that 43.4% of COVID-19+ cases have symptoms lasting longer than 30 days, and 24.1% still have at least one symptom after 90 days. "
- "These numbers are higher for COVID-19+ cases who were initially more ill, 59.4% at 30 days and 40.6% at 90 days, "
- "but even for very mild and initially asymptomatic cases, 14.3% have complications persist for 30 days or longer."
