| combined testing for antibodies to rubella non-structural and envelope proteins sentinels infections in two outbreaks. | two separate outbreaks of rubella occurred in hamilton, ontario, canada, 7 yrs apart, with a peak incidence for both in the month of april. a total of 138 cases, 51 in 1978 and 87 in 1985, was observed, the majority being in adolescents and young adults 15-25 years of age. cases were diagnosed by the presence of rubella igm antibody or the combination of a negative passive hemagglutination (rubacell-abbott) and a positive enzyme immunoassay (eia) or hemagglutination inhibition (hi) test on a sin ... | 1987 | 3326708 |
| rubella virus infections during pregnancy, toronto, 1963-66. | among 670 pregnant women who attended the antenatal clinics of two toronto city hospitals and one suburban hospital between may 1963 and january 1966, 29 of 550 patients apparently acquired rubella neutralizing antibodies, including 12 whose initial sera were collected during the first trimester. none developed overt rubella. although rubella antibodies were detected in 61 to 79% of mothers aged 20 years or more, and antibody conversions were detected in 4 to 10% of mothers in each five-year age ... | 1966 | 5921475 |
| can we prevent an increase in the incidence of congenital rubella syndrome in the next decade? | the immunity to rubella of 115 girls aged 10 to 14 years was tested in 1978. the proportion of girls found to be immune was 80%, similar to rates in the prevaccination era. nearly half of the immunity was from documented vaccination, and the other half was presumably from infection with wild rubella virus. the vaccination failure rate was 12%. because of declining immunity to rubella of women of child-bearing age, detecting low levels of immunity in these women is becoming increasingly important ... | 1981 | 7260807 |
| rubella antibody titres and immunization status in a family practice. | rubella vaccination status and immunity to rubella were studied in 230 "active patients" aged 8 to 22 years in a teaching family practice by means of a chart review and measurement of the rubella antibody titre in a blood sample. of the 200 patients who submitted a blood sample 161 (80%) were found to be immune, having a rubella hemagglutination-inhibiting antibody titre of 1:16 or greater. log linear analysis showed that immunity to rubella was independent of a history of rubella, and that 94% ... | 1980 | 7370858 |
| rubella immunity among prenatal women in ontario, 2006-2010. | countries of the americas have been working towards rubella elimination since 2003 and endemic rubella virus transmission appears to have been interrupted since 2009. to contribute towards monitoring of rubella elimination, we assessed rubella seroprevalence among prenatal screening tests performed in ontario. | 2013 | 23914729 |
