Rubella seroprevalence in women in the reproductive period, Mersin, Turkey

Seroprevalence of rubella in the cord blood of pregnant women and congenital rubella incidence in Nha Trang, Vietnam

“…Our multivariate analysis supported no association of parity or maternal educational status with rubella susceptibility, which is consistent with findings elsewhere [23][24][25][26]. Apparent association on univariate analysis was probably due to increased maternal age as a confounding factor, although there might be a potential risk of transmission from elder siblings to mothers.…”

“…For example, some studies conducted before rubella vaccination was introduced found lower levels of seropositivity in rural than in urban areas [27], one recent study found the converse [25], while no association was identified elsewhere [23,26] as seen from this study. Rubella-specific IgM tests identified three infants with CRI, which implies a CRI rate of 151 (95% CI: 0-322) per 100,000 live births.…”

Rubella seroprevalence in pregnant women at the military teaching hospital, Rabat, Morocco

“…In data from some countries, rubella seropositivity seems to increase with age [4]. However, in other studies, such as the present study, no significant differences between age groups were reported [4].…”

“…In data from some countries, rubella seropositivity seems to increase with age [4]. However, in other studies, such as the present study, no significant differences between age groups were reported [4]. This is probably owing to the early exposure of children and adolescents to rubella infection; in adulthood, the seropositivity rate seems to stabilize.…”
