Pennsylvania issues alert on congenital measles—something US hasn't seen for decades
摘要
美国宾夕法尼亚州卫生部发布健康警报，因孕期麻疹及由此引发的先天性麻疹病例持续增加。州卫生部门指出，在当前疫情暴发前，先天性麻疹病例已数十年未见。警报包含孕期麻疹暴露与病例管理及新生儿病例的详细临床指导。由于麻腮风疫苗数十年成功使用，许多医生职业生涯中从未见过此类病例。但随着全国疫苗接种率下滑，这种高传染性病毒更易在疫苗接种不足的社区立足并快速传播。截至10月
Pennsylvania's health department issued a health alert Monday as cases of measles in pregnancy and, in turn, cases of congenital measles have continued to increase. Before the current outbreak—which continues to rage across the state—congenital measles cases hadn't been seen in decades, the department noted in its advisory.
The alert included detailed clinical guidance for managing measles exposures and cases during pregnancy as well as cases in newborns. Many doctors have never seen such cases in their careers given the decades of successful use of the measles, mumps, and rubella (MMR) vaccine. But now, with vaccination rates slipping nationwide, the highly infectious virus is better able to get footholds in communities and spread rapidly through under-vaccinated pockets, as is happening in Pennsylvania.
As of October 19, Pennsylvania had reported 1,286 measles cases this year across 42 counties. Of those, 247 have been hospitalized, and six people have reportedly died (though the latest reported death is still pending an investigation by the state health department before it is added to the state tally).
