Infection

    Mono (mononucleosis).

    Mononucleosis mostly affects teens and young adults. There's no specific treatment, so care focuses on rest, hydration, and monitoring for spleen enlargement.

    Quick answer

    Mono is a viral infection (usually Epstein-Barr) causing extreme fatigue, sore throat, and swollen glands. We test on-site and provide supportive care — most patients recover in 2–4 weeks.
