We describe the dynamics of dengue virus (DENV) infection in a woman in her mid-30s who developed fever after returning from Sri Lanka to Italy in April 2017. Laboratory testing demonstrated detectable DENV-RNA in plasma, urine, saliva, vaginal secretion. Persistent shedding of DENV-RNA was demonstrated in vaginal secretion, and DENV-RNA was detectable in the pelleted fraction up to 18 days from symptom onset. These findings give new insights into DENV vaginal shedding and vertical transmission.
我们描述了一名35岁左右女性的登革热病毒（DENV）感染动态，该女性于2017年4月从斯里兰卡返回意大利后出现发热症状。实验室检测显示，在血浆、尿液、唾液、阴道分泌物中可检测到DENV-RNA。阴道分泌物中证实存在DENV-RNA的持续脱落，并且从症状发作起18天内，在沉淀部分均可检测到DENV-RNA。这些发现为DENV的阴道脱落和垂直传播提供了新的见解。
