Abstract
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.
