people who are healthy but see a doctor because they think that they may have a disease or medical problem

Too much money is spent treating the worried well rather than people who are actually sick. 太多的钱花在治疗焦虑自己身体状况的健康人身上，而不是真正的病人。

Nearly 500 people died of the disease and more than 6,600 were "worried well", concerned that they, too, were infected. 近500人死于这种疾病，6600多人“毫无必要地怀疑”自己也感染了这种病。
