Introduction. Measles is a virical disease that may be serious in children aged >1 year. Methods and results. Since 1985 six seroprevalence studies in representative samples of the population have been carried out. Seroprevalence of measles in children aged 6-14 years and pregnant women was studied in 1985; seroprevalence in population aged ≥5 years was studied in 1996 and 2003; and seroprevalence in neonates and pregnant women was studied in 2003 and 2013. Studies carried out in 1996 and 2002 (population aged ≥5 years) found a prevalence of protective levels of 98.5% and 95.5%, respectively. Studies carried out in 2003 and 2013 in neonates (umbilical cord) found prevalence of protective levels (>300 UI/ml) of 98.6% and 91.5%, respectively. Protective levels had decreased 7% between 2003 and 2013 due to the lower protective levels in pregnant women aged <35 years (<91%) in 2013. Conclusions. The studies of seroprevalence carried out in Catalonia suggest that great part of the population is protected against measles, although immunity levels have decreased in population aged <35 years.
