If a person is asymptomatic, or if the illness they have is asymptomatic, the body shows no signs. No fever, no cough, no rash — nothing you can point to. That does not mean “not ill” and it does not mean “only a little ill.” Though actually, this is the bit students (and news readers) slide past: you can have the virus, or the disease, and feel completely fine. Mild means the signs are small. Asymptomatic means there are no signs at all. Doctors care because an asymptomatic person may still pass the illness on. The word is medical and a little stiff; after Covid, though, a lot of ordinary people learned it. You will hear it about tests, outbreaks, and check-ups. Some hospital talk even uses asymptomatic as a noun for “people with no symptoms,” but that is inside-the-clinic language, not the way to speak to a friend.
組成a- (“not”) + symptomatic (“showing signs of illness”). So: not showing symptoms. The noun use comes from this adjective.
