A young, healthy person may experience COVID similarly to a mild cold or flu virus — fever, cough, chills, sore throat, headaches — or they may not experience any symptoms at all. However, even young people may become sick enough to require hospitalization or intensive care, or even die.
A young, healthy person can also still become a “long-hauler,” someone who continues to suffer from fatigue, shortness of breath, or other symptoms weeks or months later.
For example, two locals share their experience with "long COVID" in an interview with the Star-Advertiser. You can read their story at https://www.staradvertiser.com/2022/02/14/hawaii-news/hawaii-residents-share-their-struggles-with-long-covid/.
