Long COVID refers to a range of health issues that persist or reoccur following acute COVID-19 illness, including symptoms like fatigue, respiratory problems, and neurological symptoms.

The study analyzed data from the 2022 Behavioral Risk Factor Surveillance System survey, which included noninstitutionalized U.S. adults aged 18 years and above. Researchers surveyed respondents about their previous COVID-19 diagnosis and any experiences of Long COVID. Long COVID was defined as the presence of symptoms lasting at least three months that developed after a COVID-19 infection.

The findings revealed that 6.4% of U.S. adults reported ever experiencing Long COVID. The prevalence varied significantly across different states and territories. The lowest prevalence was found in the U.S. Virgin Islands, where only 1.9% (95% CI = 0.9%-4.1%) of respondents reported Long COVID. On the other hand, West Virginia had the highest prevalence, with 10.6% (95% CI = 9.5%-11.8%) of adults reporting Long COVID. Prevalence exceeded 8.8% in seven states. The prevalence tended to be lower in New England and the Pacific regions, while it was higher in the South, Midwest, and West.

The study had some limitations, as it did not consider factors such as treatment received during acute COVID-19 infection, the time since infection, or the severity and duration of symptoms. Additionally, information about COVID-19 vaccination was not included in the report for all jurisdictions.

However, the study's findings highlight the need for ongoing assessment and surveillance of Long COVID at the state and territory level. This information can be valuable in informing policy decisions, planning healthcare interventions, and providing support to individuals experiencing Long COVID. The data can also help identify potential disparities across different regions of the country and guide efforts to promote health equity.

The authors of the study emphasized the importance of addressing the healthcare needs of individuals with Long COVID. The findings not only contribute to filling the knowledge gap around Long COVID prevalence but also provide a foundation for future research and initiatives to provide better care and support to those affected.

This study serves as a critical step towards understanding the prevalence and impact of Long COVID on adults in the United States. Further research and surveillance efforts are necessary to better comprehend the long-term effects of COVID-19 and develop comprehensive strategies to mitigate its consequences.

The CDC encourages continued monitoring and tracking of Long COVID prevalence to facilitate evidence-based decision-making and targeted interventions. By understanding the scope of Long COVID, healthcare professionals and policymakers can work towards providing comprehensive care and support for those affected by this post-COVID condition.
