Epidemiologic survey of documented measles outbreak in Tehran

In spite of extended vaccination programs against measles, it is the most preventive contagious disease that leads to death. For adaptation of WHO policy for measles in Iran; we should determine susceptible age population whom at present lay out of current vaccination program. Methods and Materials: In this descriptive study which was performed in the public health School of the Tehran medical university; we obtained 131 documented measles cases among 650 suspected case of measles (as WHO discrimination) According to serum samples analysis (capture IgM EIA 71% and 29 % HI). In this study 63. 4 % of cases were male and 39.6 % were females. Between patients, the most prevalent age group was between 15 - 19 years old. Two peaks of the time of the disease were March and June. History of past vaccination against measles showed that 43 % had unknown history; 24. 4 % had two vaccination; 39. 3 % had one vaccination and 3.1 % had no vaccination history. It is suggested (by further investigations in future) the need for revaccination of measles for age group of 15-19 in Iran will be determined.
