In essence, criteria for diagnosis consisted of a compatible clinical syndrome—fever, lymphadenopathy, and sore throat—plus supportive laboratory evidence —relative and absolute lymphocytosis persisting at least 10 days and properly interpreted serologic tests. The heterophile test must be significantly positive and must persist
