Beta-haemolytic streptococci were isolated from 35% of 525 children who presented to their family doctors with sore throat. The first 306 were investigated bacteriologically and virologically and beta-haemolytic streptococci were isolated from 30% and viruses from 14.7%. The ages which had the highest incidence of sore throat, for both sexes, were 7, then 6, 8, and 5. Those with tonsils had a higher incidence of beta-haemolytic streptococci than those without, but the presence or absence of tonsils made no difference to the degree of growth of the streptococci.Viruses were isolated predominantly during the winter months, but streptococci, though mostly isolated in winter, were isolated throughout the rest of the year.
在因喉咙痛前往家庭医生处就诊的525名儿童中，35%分离出了β溶血性链球菌。对前306名儿童进行了细菌学和病毒学调查，分离出β溶血性链球菌的占30%，分离出病毒的占14.7%。无论男女，喉咙痛发病率最高的年龄段是7岁，其次是6岁、8岁和5岁。有扁桃体的儿童β溶血性链球菌感染率高于没有扁桃体的儿童，但扁桃体的有无对链球菌的生长程度没有影响。病毒主要在冬季分离出来，而链球菌虽然大多在冬季分离得到，但在一年中的其他时间也有分离出。
