Long COVID is a serious illness affecting anyone who had a SARS-CoV-2 infection, including children [1].

The condition matters because it can result in chronic conditions that require comprehensive care and, in some cases, cause permanent disability [1, 2]. Because the symptoms linger long after the initial virus is gone, patients often struggle to find effective treatment pathways.

Data suggests that approximately five percent of U.S. adults are living with long COVID [3]. The illness is characterized by lingering physical and mental effects, which researchers believe may be driven by chronic inflammation [2].

For some, the onset of symptoms is abrupt. Maureen Dodge, who first contracted COVID-19 in February 2024 [4], described her experience with the illness. "I was getting my strength back, and then approximately two weeks later it just hit me like a brick," Dodge said [4].

The medical community continues to seek answers through clinical trials and personal study. Alison Cohen, PhD, MPH, is both a researcher and a patient. "I’m a long-COVID researcher and I have long COVID," Cohen said [3].

Other patients have found relief through experimental medical interventions. Shayna Bhalla said that a specific clinical trial changed her life [5]. These efforts to identify biological markers and treatment protocols remain ongoing as of 2025 [3].

Public health agencies emphasize that the condition requires a multidisciplinary approach to care. This includes managing the inflammatory response, and providing mental health support to those dealing with the long-term impacts of the virus [1, 2].

“Long COVID is a serious illness that can result in chronic conditions and cause disability.”

The persistence of long COVID years after the initial pandemic peak indicates that SARS-CoV-2 created a secondary public health crisis. The shift toward studying chronic inflammation suggests that the medical community is moving away from treating the virus as a temporary respiratory infection and toward treating it as a systemic autoimmune or inflammatory disorder.
