长期新冠究竟影响多少人？研究发现早期数据或有偏差

Recent research challenges the understanding of long COVID, suggesting that many cases previously classified as such may have been misdiagnosed or overestimated in prevalence. According to Australian government definitions, long COVID refers to symptoms persisting for at least 12 weeks post-infection, yet there is currently no clinical testing method to confirm its diagnosis. This lack of reliable testing complicates the assessment of how many individuals are truly affected by long COVID.

Experts emphasize that while some patients may be misdiagnosed, their suffering is real, and the underlying causes of their symptoms may stem from other diseases. Research from Stanford University indicates that long COVID might resemble other post-viral syndromes, diverging from previous beliefs. The Australian government anticipates that by the end of 2023, over 1.3 million long COVID cases will be reported, with estimates suggesting that 5-10% of COVID-19 patients experience lingering symptoms three months after infection.

The complexity of long COVID symptoms, which can affect various organ systems and overlap with other conditions, presents significant challenges for diagnosis and treatment. Experts warn that without reliable diagnostic methods, some patients may not receive appropriate care and may even be dismissed by healthcare providers. Ongoing research aims to better understand the long-term impacts of COVID-19 on public health and prepare for future health crises.
