Long COVID Quiz
Brain fog, POTS, fatigue — what we know about post-acute SARS-CoV-2
Brain fog, POTS, fatigue — what we know about post-acute SARS-CoV-2
About 1 in 5 people who get COVID develop Long COVID symptoms — and post-exertional malaise, the worsening of symptoms 24-72 hours after even mild exertion, is the hallmark feature. Long COVID can cause more than 200 different symptoms ranging from brain fog to POTS to crushing fatigue, and the NIH RECOVER initiative is funneling over a billion dollars into understanding it. This quiz covers symptoms, mechanisms, treatments, and the cultural moment that shaped the disease.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the WHO definition of Long COVID, post-exertional malaise, POTS and dysautonomia, parosmia, microclot research, the metformin-Paxlovid story, low-dose naltrexone, pacing and the spoon theory, and patient-led groups like Body Politic and the Patient-Led Research Collaborative.
Long COVID, or Post-Acute Sequelae of SARS-CoV-2 (PASC), is a condition where symptoms persist or develop three months or more after an initial COVID-19 infection and last at least two months. It can affect nearly every organ system and includes more than 200 reported symptoms.
Post-exertional malaise (PEM) is a worsening of symptoms — fatigue, brain fog, pain, and more — that follows physical, mental, or emotional exertion, typically with a delay of 12-72 hours. It's the hallmark of ME/CFS and is common in Long COVID.
Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia where heart rate jumps by 30+ beats per minute (40+ in teens) within 10 minutes of standing. It commonly emerges after viral illness and is a frequent Long COVID complication.
