SUMMARY
Dengue is a systemic viral infection that is commonly transmitted between humans via mosquitoes. Other modes of transmission such as the vertical one are rare and have been infrequently reported in the literature. This report investigates one case of vertical transmission of dengue in Guangzhou, China. A G1P1 lady at 39 weeks of gestation was referred to the Huzhong Hospital presenting a fever for two days. She subsequently developed a skin rash on the back and lower limb and at that time she had already experienced five days of fever. She subsequently went into labor and delivered a female neonate weighting 3,500 g at birth. The neonate developed fever on the third day of life which was associated with a systemic erythematous skin rash. There was no report or evidence of mosquito bites after birth. A complete blood count showed leucopenia, thrombocytopenia and anemia and the liver function test showed elevated AST, GGT and bilirubin. Dengue was diagnosed in the mother and the neonate by the ELISA dengue virus NS1 antigen test (Wantai, Beijing, China) and dengue virus fluorogenic quantitative PCR test (Liferiver, Shanghai, China).The case report illustrates the possibility of the vertical transmission of dengue. Clinicians should be alert to this possibility and institute early treatment. Further direct evidence and research are required.
