Although rubella serosusceptibility among women of reproductive age in West Africa ranges from 10% to 30%, congenital rubella syndrome has not been reported. In Ghana, rubella immunization and serologic testing are unavailable. Our objectives were to identify congenital rubella syndrome cases, ascertain rubella antibody seroprevalence during pregnancy, and recommend strategies for congenital rubella syndrome surveillance.
Congenital rubella syndrome cases were identified through prospective surveillance and retrospective surveys of hospital records. A rubella serosurvey of pregnant urban and rural women was performed.
Eighteen infants born within a 5-month period met the congenital rubella syndrome case definitions, coinciding with a 9-fold increase in presentation of infantile congenital cataract. The congenital rubella syndrome rate for this otherwise unrecorded rubella epidemic was conservatively estimated to be 0.8 per 1000 live births. A postepidemic rubella immunity rate of 92.6% was documented among 405 pregnant women; susceptibility was significantly associated with younger age (P = .000) and ethnicity (northern tribes, P = .024).
Congenital rubella syndrome occurs in Ghana but is not reported. Information about congenital rubella syndrome and rubella in sub-Saharan Africa is needed to evaluate inclusion of rubella vaccine in proposed measles control campaigns.
尽管西非育龄女性的风疹血清学易感性范围为10%至30%,但尚未有先天性风疹综合征的报告。在加纳,无法获得风疹免疫接种和血清学检测。我们的目的是识别先天性风疹综合征病例,确定孕期风疹抗体血清阳性率,并推荐先天性风疹综合征监测策略。
通过对医院记录进行前瞻性监测和回顾性调查来识别先天性风疹综合征病例。对城市和农村孕妇进行了风疹血清学调查。
在5个月内出生的18名婴儿符合先天性风疹综合征病例定义,同时婴儿先天性白内障的发病率增加了9倍。对于这次此前未记录的风疹疫情,先天性风疹综合征的发病率保守估计为每1000例活产中有0.8例。在405名孕妇中记录到疫情后风疹免疫率为92.6%;易感性与年龄较小(P = .000)和种族(北部部落,P = .024)显著相关。
先天性风疹综合征在加纳存在但未被报告。需要有关撒哈拉以南非洲先天性风疹综合征和风疹的信息,以评估在拟议的麻疹控制运动中纳入风疹疫苗的情况。
