I am looking for the word for someone who never shows any symptoms of a disease. I am not looking for the word asymptomatic.
Asymptomatic is often used for people who initially display no symptoms but go on to develop symptoms as the disease progresses.
I have read a medical report with this term in it but I can't remember it.
Note: The following was added to this question only after the first answer was provided.
I remember reading it as: [something]symtomacis and [something]-symtomatic. for example - wordsymtomatic and word-symtomatic.
Found it! The word is paucisymptomatic. Also written pauci-symptomatic.
