A study of diphtheria in Iran was undertaken during the summer of 1969. Diphtheria was found to be more common among the younger people and to reach its peak 3 months after the start of the school term, during the coldest period of the year. Owing to the liberal use of antibiotics a number of modified clinical cases were observed. Of the strains isolated, 89.7% were gravis, 1.3% intermedius and 9% mitis. Phage typing of these strains showed that the mitis and intermedius strains could only be typed by adapted phages and the majority of gravis strains were phage type XIV, which is the epidemic type seen in other countries.As the mass immunization campaign reduces the incidence of diphtheria in Iran, the epidemiological pattern of the disease will change as seen in the U.K. and U.S.A. It is, therefore, suggested that in the future further studies of diphtheria in Iran be undertaken in order to provide us with information about the changing epidemiological pattern of the disease.
1969年夏天，伊朗开展了一项关于白喉的研究。研究发现，白喉在年轻人中更为常见，且在学年开始3个月后、一年中最冷的时期达到高峰。由于抗生素的广泛使用，观察到了一些症状有所改变的临床病例。在分离出的菌株中，89.7%为重型，1.3%为中间型，9%为轻型。对这些菌株进行噬菌体分型显示，轻型和中间型菌株只能用适应性噬菌体进行分型，大多数重型菌株为噬菌体十四型，这是在其他国家可见的流行型。随着大规模免疫接种运动降低了伊朗白喉的发病率，该病的流行病学模式将如英国和美国那样发生变化。因此，建议今后在伊朗对白喉进行进一步研究，以便为我们提供有关该病不断变化的流行病学模式的信息。
