Post-infectious illness is nothing new. In neurology, as in other specialties, there are multiple diagnoses that occur following infection. This could happen immediately thereafter, a few weeks later, a few months later, or sometimes even longer. It is not necessarily the same as what we refer to as relapsing-remitting, as once the chronicity of the symptoms begins, there is never a real return to one's health baseline.
There are delayed effects of many exposures we are subject to, which include not only infectious organisms but also environmental contaminants, radiation, and even necessary therapeutic regimens such as chemotherapy.
In kids, we see post-infectious illnesses such as acute demyelinating encephalomyelitis (ADEM), transverse myelitis (TM), and febrile infection-related epilepsy syndrome (FIRES) as examples.
In adults, we see diagnoses such as Guillain Barre syndrome (GBS) and myalgic encephalomyelitis chronic fatigue syndrome (MECFS) as examples. Indeed, there has been recent research and dialogue regarding the potential of other diagnoses such as multiple sclerosis (MS) and Alzheimer’s disease (AD) as post-infectious processes.
We have seen the long-term effects of COVID-19. Commonly referred to as long Covid or long hauler or post-acute sequelae SARS-CoV-2 infection (PASC). Symptoms of post-Covid include chronic fatigue, exercise intolerance, difficulty breathing, cognitive changes, headaches, dizziness, hypersensitivities, sleep dysfunction, neuropathy, difficulty with focus and concentration, and more. This is very similar to what is seen in MECFS, so it is thought to be more of a systemic post-infectious illness.

Many patients with long Covid report having only mild symptoms with the acute infection, which were thought to be improving or resolving only to worsen again after some period later.
