Dengue in pregnancy: Review article.

Dengue is the most common viral mosquito- borne disease. It is a major public health problem, especially in tropical and sub-tropical areas worldwide. According to the World Health Organization (WHO), approximately 40% of the world's population (over 2.5 billion people) live in areas with high risk of contracting dengue infection. Adults of childbearing age and pregnant women are travelling more frequently to tropical areas. Therefore exposing themselves to specific arboviral infections such as dengue, which may impact ongoing and future pregnancies. Clinical manifestations of dengue are wide ranging from asymptomatic to needing intensive care in cases of hemorrhagic dengue fever. The effects of dengue during and on pregnancy are unclear, moreover there is a lack of a cohesive reference to inform women of reproductive age who live in or travel to endemic areas and are at risk of contracting dengue. Here we present review of literature specifically looking at etiology, pathogenesis, clinical manifestations, management of dengue in pregnancy as well as its effect on maternal health and fetal outcomes. There is clear evidence to suggest adverse maternal outcomes in women with symptomatic dengue in low resource countries. A high index of clinical suspicion and early referral to tertiary center will prevent maternal -fetal serious adverse events in endemic areas. This review will help Clinicians in advising as well as managing women who travel during pregnancy to endemic areas as well as clinicians based in endemic areas who are managing women with dengue in pregnancy.
