Post-acute infection syndrome

Post-acute infection syndrome
Other namesPostviral syndrome

Post-acute infection syndromes (PAISs) or post-infectious syndromes are medical conditions characterized by symptoms attributed to a prior infection. While it is commonly assumed that people either recover or die from infections, long-term symptoms—or sequelae—are a possible outcome as well.[1] Examples include long COVID (post-acute sequelae of SARS-CoV-2 infection, PASC), Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and post-Ebola virus syndrome.[1] Common symptoms include post-exertional malaise (PEM), severe fatigue, neurocognitive symptoms, flu-like symptoms, and pain. The pathology of most of these conditions is not understood and management is generally symptomatic.
