“…Epidemiological data of the current outbreak showed that 54 % of cases were below 1 year of age. Infants become susceptible due to the drop in maternal antibodies from the third to the sixth month of life [11][12][13][14]. Many mothers were born after 1978, when the one-dose measles vac-cination scheme was implemented.…”

Measles resurgence in Argentina: 1997–8 outbreak

Epidemiological and clinical findings from 1162 serologically confirmed measles cases occurring in Buenos Aires, Argentina in 1997 and 1998 were retrospectively reviewed. From 90 hospitalized children, measles virus was detected by direct RT-PCR from nasopharyngeal secretions. Patients were grouped as follows: (i) not vaccinated: infants < 12 months; (ii) regularly vaccinated: children 1-4 years not covered by the last catch-up; (iii) catch-up vaccinated: patients 5-19 years immunized during the 1993 campaign. Most cases were recorded in non-vaccinated infants (54%), and the lowest in catch-up vaccinated children (16%). Mean age of the 90 hospitalized children was 11.3 months. Pneumonia was the major hospitalization cause followed by pneumonitis. Two children required intensive care and one died. The 1993 catch-up campaign seemed to reduce the number of cases in the 5- to 19-year-old group. Lack of timely follow-up probably led to the accumulation of susceptible individuals allowing measles re-emergence. Direct viral detection by RT-PCR proved to be a sensitive tool for molecular epidemiology surveillance.

“…Other possible factors responsible for this high primary vaccine failure include nutritional status of children [11], acute disease during vaccination [12][13][14] and concomitant administration of gamma globulin [15], race, environmental factors [16,17], sex [18] and immunity status of those being vaccinated [19,20]. In our study, sex and literacy were not statistically important factors in primary vaccine fail-ure.…”

An outbreak of measles due to secondary vaccine failure prompted this investigation into the prevalence of measles antibody in children. We studied 608 children in 7 different age groups:6, 9, 14 and 18 months and 6, 10 and 15 years. Children in the 2 youngest groups received no vaccination; the rest were vaccinated at 9 months and 15 months. The 15-year-old age group received an additional vaccination. Transplacental measles antibody [Ab] decreased from 10.0% at 6 months to 0% at 9 months. Measles Ab was positive in 52.9% [14 months], 89.4% [18 months], 60.8% 96 years], 45.0% [10 years] and 96.8% [15 years]. To increase Ab levels, a booster vaccination is recommended, administered either with the second DPT booster or at pre-high school age

“…Well-documented ones are prior measles virus (MV) exposure that produces higher MMA than measles immuniza on. Previous study conducted by Bromberg et al 12 in 1994, demonstrated that mothers from developing na ons had higher levels of MMA than those in developed countries. Another study carried out in the United Kingdom by Brugha et al 13 in 1996, similarly showed a higher MMA in mothers with a history of natural MV exposure.…”

Introduction: Maternal measles antibody (MMA) offers protection against measles in early childhood, however, certain determinants of this antibody lives much to be desired. The aim of the study were to determine the association between birthweight (BW) and gestational age (GA), to assess the relationship between BW and MMA, to correlate GA with MMA and to examine the combined effects of BW and GA on MMA.Material and Methods: The work was a hospital-based cross-sectional descriptive study. Babies were enrolled using systematic random sampling method. The babies BW was measured using the bassinet scale; enzyme linked immunosorbent assay was used to determine MMA. GA of babies was determined using the mothers' last menstrual period (LMP) or by Dubowitz score or by Obstetric ultrasound scan. Data were analysed using SPSS statistical software version 16, Illinois, Chicago USA and a computer program for epidemiologist PEPI version 3.01. Spearman’s correlation (rho), Kendall’s rank correlation (tau b) and Jonckheere-Terpstra test of association of ordinal variables were determined. Univariate analysis was used to investigate the combine effects of BW and GA on MMA. Likely-hood ratio Chisquare (?2) was used for categorical data. Goodman-Kruskal index rank order of predictive association (tau) of ordinal data was also calculated.Results: 200 babies were enrolled, 101 (50.5%) were males and 99 (49.5%) females. 169 babies (84.5%) had normal BW, 117 (58.5%) were delivered at term. The mean BW was 3.04 (0.58) at 95% CI (2.96 – 3.12) kg. Association between BW and GA was significant (p=0.003), the predictive value for the association was also significant (p=0.039). Significant correlation was also observed between GA and MMA (p<0.001).Conclusions: There was a significant association between BW and GA and MMA correlated well with GA.J Nepal Paediatr Soc 2015;35(1):6-12
