Background And Objective:
Considering recent outbreaks of rubella in immigrant population in Madrid (Spain), we investigated the proportion of rubella susceptibility in immigrant women in Catalonia, Spain.
Patients And Method:
Seroprevalence study in pregnant women of the immigrant community. Information of demographic possible risk factors associated to rubella susceptibility was collected.
Results:
Five hundred and ninety four women were included. The global prevalence of susceptibility was 11.7% (95% confidence interval [CI], 9.2-14.5%). African women showed the highest susceptibility (17%; 95% CI, 10.5-25.2%). Age younger than 25 years was a risk factor statistically associated with rubella susceptibility (adjusted odds ratio=3.02; 95% CI, 1.09-8.35).
Conclusions:
Rubella susceptibility in pregnant women from low income countries is 10 times higher than that of Catalonian native women.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
