To determine incidence of measles and progress towards its elimination in Saudi Arabia.
A retrospective analysis of routinely collected active and passive surveillance data on measles at the Ministry of Health, Saudi Arabia. All laboratory confirmed measles from (2009-2012) were analyzed to determine measles annual incidences and distribution by age, gender, nationality, seasonality, vaccination status and spatial distribution by region.
Measles incidence per 1,000,000 populations increased from 3.2 in 2009 to a peak of 12.8in 2011 and a slight fall to 9.9 in 2012. About 50% of cases were in children under-five years, 12% were infants and 33% were 15 years and above. Of the total, 39%were unvaccinated and16% had unknown vaccination status. Fifty-five percent of infants were not due for vaccination. Of children <5 years, 42% received vaccination. Spatial distribution is not countrywide in each of the four years but seemed to concentrate in the central and South West regions with40% in Jizan and Jeddah.
High incidence of confirmed measles among unvaccinated infants requires strengthening of the immunization services. Improvement in measles case surveillance for completeness of vaccination status, vaccination of unvaccinated youths and comprehensive immunization are needed for measles elimination.
确定沙特阿拉伯麻疹的发病率和消除进展。
对沙特卫生部常规收集的麻疹主动和被动监测数据进行回顾性分析。对（2009-2012 年）所有实验室确诊的麻疹病例进行分析，以确定麻疹的年发病率和年龄、性别、国籍、季节性、疫苗接种状况的分布情况，并按地区进行空间分布。
每 100 万人的麻疹发病率从 2009 年的 3.2 例上升到 2011 年的 12.8 例高峰，然后略有下降到 2012 年的 9.9 例。约 50%的病例发生在五岁以下儿童中，12%为婴儿，33%为 15 岁及以上。在所有病例中，39%未接种疫苗，16%的疫苗接种状况未知。55%的婴儿未到接种疫苗的年龄。在<5 岁的儿童中，有 42%接受了疫苗接种。四年中，空间分布并非在全国范围内，但似乎集中在中央和西南部地区，其中吉赞和吉达占 40%。
未接种疫苗的婴儿中确诊麻疹发病率高，需要加强免疫服务。需要提高麻疹病例监测的完整性，包括疫苗接种状况、为未接种疫苗的青少年接种疫苗以及开展全面免疫，以实现消除麻疹。
