Recent data from the US has shed light on the prevalence of long COVID among American adults. According to the findings, an estimated 6.9 percent of American adults, or approximately 17.8 million individuals, have experienced long COVID as of early 2023. This data reveals significant demographic differences among US adults, highlighting which groups are more susceptible to the lingering effects of COVID-19.
The data shows that females are more likely to report experiencing long COVID compared to males, with 8.6 percent of females reporting symptoms compared to 5.1 percent of males. Additionally, younger and older adults had lower rates of long COVID compared to middle-aged adults. Vaccinated individuals who had received a booster shot also showed lower rates of long COVID compared to those who had only received two doses of a COVID-19 vaccine or were unvaccinated.
The analysis identified pre-existing chronic health conditions and obesity as clear risk factors for long COVID. Other risk factors included high blood pressure, depression, diabetes, and chronic obstructive pulmonary disease (COPD). However, the overall prevalence of long COVID varies depending on how it is defined, including the duration of symptoms and which symptoms are considered.
Studies from around the world have provided varying estimates of long COVID prevalence. In Scotland, 6.5-10 percent of adults were found to have long COVID 6-18 months after infection, while 5-10 percent of Australian adults reported persistent symptoms 3 months post-infection. In the Netherlands, one in eight individuals (12.7 percent) had experienced long COVID as of August 2022.
Estimates of long COVID globally have been met with skepticism, with researchers debating the accuracy of extrapolating from national studies to calculate the total number of individuals affected. Some argue that the true toll of long COVID is likely underestimated, considering the number of cases that go undocumented in health records and surveys.
Despite advancements in treating acute COVID-19 cases, the burden of long COVID persists for individuals who continue to struggle with persistent symptoms. As the debate over the true prevalence of long COVID continues, it is evident that more research and support are needed to address the ongoing challenges faced by long-haulers.
The new evidence from the US provides valuable insights into the prevalence and demographic variations of long COVID. While the data helps inform healthcare responses, it is essential to remember the individual experiences of those living with the long-term effects of COVID-19. Continued research and support are crucial in tackling the complexities of long COVID and providing relief for those affected by this chronic condition.
