A study published in the JAMA Network showed that 6.2 % of 1.2 million people experienced at least one of the three long COVID symptoms, namely persistent fatigue with bodily pain or mood swings, cognitive problems, or ongoing respiratory problems after three months of acute infection onset. In the meta-analysis study, 54 studies were taken for analysis, out of which 44 were published studies and 10 were collaborating cohort trials. 

The study revealed that 15.1% of the patients continued to experience long COVID symptoms for more than 12 months. The study also revealed that the risk of long-term COVID was greater in female patients in comparison to their male counterparts.

Similarly, the risk of long COVID symptoms was also found to be greatest in those who needed hospitalization for the initial SARS-CoV-2 infection, particularly among those needing intensive care unit care.

The findings of the study revealed that one of the three self-reported long COVID symptom clusters included 3.7% for ongoing respiratory problems, 3.2% for persistent fatigue with bodily pain or mood swings, and 2.2% for cognitive problems after adjusting for health status before COVID.
