Major Chinese Study Finds 75%+ COVID-19 Patients are ‘Long Haulers’

Major Chinese Study Finds 75%+ COVID-19 Patients are ‘Long Haulers’

Well known Chinese researcher Bin Cao led a study in China led a substantial study, perhaps the largest thus far, in Wuhan, China, revealing that a majority of COVID-19 patients will experience long term or “Long COVID” symptoms, such as fatigue, insomnia, depression and/or anxiety and reduced lung function. Investigating the Long COVID phenomenon in 1,733 patients that were infected with SARS-CoV-2 later discharged in the Wuhan area, over 75% of them reported at least one symptom a half year later. The findings further add to the growing data about what scientists and doctors know about COVID-19—it’s symptoms tend to linger for a long time for most people.

Published in The Lancet, the study team investigated 1,733 patients admitted to Yin-tan Hospital from Jan 7 2020 to May 29, 2020. Spanning a median review of 14 days, the investigators report on the findings of this investigation overing a population with a median age of 57. The study team conducted exams, tests as well as the “six-minute walk test” a standard measure for endurance and aerobic health. The investigators also conducted some lung tests, chest CT scans as well as ultrasound procedures.

Importantly, treatments such as remdesivir and dexamethasone were not in use during the period that the subjects were treated. Does this impact the results? Meaning with each new advancement in treatment offering, could that impact the severity and pervasiveness of those experiencing long-term complications?

Call to Action: The evidence mounts that SARS-CoV-2 impacts most of us that have been infected for many months thereafter. Physicians and health professionals should track these studies to learn more about evolving knowledge. COVID-19 has changed the face of healthcare and we must be armed with as much relevant information as possible to make best possible care choices.
