“…The diagnosis of infectious mononucleosis is satisfactorily documented in nine reports in this category: those by Thomsen and Vimtrup (1939, cases 1 and 3); Ricker, Blumberg, Peters, and Widerman (19471, case 1); Dolgopol and Husson (1949); Reske-Nielsen and Mogensen (1955); Erwin, Weber, and Manning (1959); Bergin (1960); Murray (1960); and Davie, Ceballos, and Little (1963). In each of these nine cases the total leucocyte count was at least 5,100/c mm and at least 1,400/c mm abnormal forms were present.…”
