A groundbreaking study has revealed that more than 1 in 5 Americans—around 23% of U.S. adults—are likely experiencing the perplexing symptoms of long COVID. This eye-opening finding was published on November 8 in the scientific journal Med, significantly higher than the previously estimated prevalence of just 7%.

Senior researcher Hossein Estiri, who leads the AI research team at Mass General Brigham in Boston, expressed optimism that these findings could shed light on the true burden of long COVID, a condition that remains largely misunderstood. "Questions about the true burden of long COVID -- questions that have thus far remained elusive -- now seem more within reach," he stated.

The research team harnessed the power of artificial intelligence to comb through extensive electronic health records, pinpointing subtle, often overlooked symptoms associated with long COVID. These symptoms can manifest across various body systems and include debilitating fatigue, persistent cough, heart issues, and the notorious “brain fog,” which typically emerge weeks to months after recovering from the initial COVID-19 infection.

Describing the capabilities of the AI tool, Estiri mentioned, "Our AI tool could turn a foggy diagnostic process into something sharp and focused, giving clinicians the power to make sense of a challenging condition."

The AI is meticulously designed to detect symptoms that are not explained by existing medical histories, that have lasted for two months or more, and that developed following a COVID infection. For instance, it can differentiate whether shortness of breath is due to long COVID or can be attributed to pre-existing conditions like heart failure or asthma.

Dr. Alaleh Azhir, the lead researcher and an internal medicine resident at Brigham and Women's, emphasized the potential impact of using AI in clinical settings. "Physicians are often faced with having to wade through a tangled web of symptoms and medical histories, unsure of which threads to pull while balancing busy caseloads. Having a tool powered by AI that can methodically do it for them could be a game-changer."

The implications of these findings are staggering, especially as the country grapples with the long-term effects of the pandemic. Researchers are committed to making their AI tool publicly accessible, aiming to equip doctors and healthcare systems for more effective diagnosis and treatment of long COVID.

As the world continues to confront the fallout of COVID-19, this study not only highlights the prevalence of long COVID but also showcases the revolutionary role that technology can play in modern medicine. Could this AI tool be the key to unlocking better healthcare for millions? Only time will tell, but one thing is clear: the battle against long COVID is far from over!
