Laut CDC-Studie variiert die Prävalenz von Long-COVID in den einzelnen US-Bundesstaaten stark

von NFI Redaktion

In a recent study published in the CDC Journal MMWR Morbidity and Mortality Weekly Report, researchers examined the prevalence of Long Coronavirus Disease 2019 (Long-COVID) in adults in the United States of America (USA). They found that the prevalence of Long-COVID varied between states and territories, ranging from 1.9% in the Virgin Islands to 10.6% in West Virginia.

Hintergrund

„Long COVID“ or „Post-COVID“ refers to various health issues that persist after an acute COVID-19 infection, including neurological and respiratory symptoms, as well as fatigue. Reports indicate that approximately 6.9% of adults in the USA were suffering from Long-COVID in 2022. However, the current lack of data from states and territories hinders targeted public health measures. The Association of State and Territorial Health Officials and the Council of State and Territorial Epidemiologists have also pointed out this gap. To address this need, the Centers for Disease Control and Prevention (CDC) conducted a nationwide study to estimate the prevalence of Long-COVID in adults.

Über die Studie

The CDC used data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) survey among non-institutionalized adults aged 18 years and older in the USA. This population-based cross-sectional survey used random-digit dialing of mobile phones (cellular and landline) to collect information on age, gender, COVID-19 history, and long COVID symptoms lasting at least three months. Prevalence estimates, standardized to the 2020 USA Census Bureau population, were calculated for all adults in all states and territories. Gender-specific weightings were applied to individuals aged 18–44, 45–64, and ≥65 years. The analysis was conducted using a Statistical Analysis System (SAS) named SUDAAN, taking into account the complex survey design.

Resultate und Diskussion

The nationwide prevalence of Long-COVID among non-institutionalized adults in the USA is 6.4%, with estimates ranging from 1.9% in the Virgin Islands to 10.6% in West Virginia. Seven states exceeded a prevalence of 8.8%. Regional differences were observed, with lower prevalence in the Pacific and New England and higher prevalence in the South, West, and Midwest. Limitations of the study include the lack of data on treatment during acute COVID-19 illness, time since illness, duration or severity of symptoms, and vaccination status in some jurisdictions.

Abschluss

In conclusion, this study fills a crucial gap by providing insights into the prevalence of Long-COVID and highlighting the need for ongoing surveillance of data on a state and territorial level to support health planning and policy decisions. The results underscore the importance of addressing the health needs of individuals with long COVID and identifying geographic differences to promote health equity through targeted interventions.
