Insights

Rubella virus infection was detected in 2.2% of Saudi children, with many experiencing hearing loss. Universal childhood vaccination contributes to the low prevalence of this infectious disease.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Immunology

Background:

  • Rubella virus infection poses a significant risk for congenital rubella syndrome and hearing impairment in children.
  • Understanding the prevalence of rubella infection is crucial for public health strategies, especially in regions with varying vaccination coverage.

Purpose of the Study:

  • To determine the prevalence of rubella virus infection among children in Saudi Arabia.
  • To assess the association between rubella infection and sensorineural hearing loss in the pediatric population.

Main Methods:

  • Serological testing for rubella virus IgM antibodies in a cohort of 1,054 children aged 12 months to 14 years.
  • Audiological evaluation, specifically assessing for bilateral sensorineural hearing loss in infected children.

Main Results:

  • A prevalence of 2.2% (23 out of 1,054 children) for rubella virus infection was identified.
  • Fifteen of the 23 infected children exhibited bilateral sensorineural hearing loss, with varying degrees of severity.
  • The study observed a lower prevalence of rubella infection compared to some international reports.

Conclusions:

  • The low prevalence of rubella infection in Saudi children is likely attributable to the successful implementation of a universal childhood vaccination program.
  • Despite low prevalence, rubella infection remains a concern due to its association with significant hearing impairment.
