A new, large study involving more than 2 million anonymized patient records found roughly one in 10 people infected with COVID-19 developed new symptoms or health conditions associated with what’s commonly referred to as long COVID more than a month later.
The analysis, appearing in JAMA Network Open, showed that such later effects occurred more frequently among people who tested positive for COVID-19 rather than negative.
Moreover, those who had more severe COVID-19 were more likely to develop new symptoms and conditions later. The findings suggest that clinicians should monitor patients’ health many months after they test positive.
The study was conducted using PCORnet®, the National Patient-Centered Clinical Research Network funded by PCORI to support more efficient large-scale research.
