Dengue is a viral infection transmitted by the bite of the female Aedes mosquito which breeds in free-standing water. It could be in your home, in potted plant trays, or even in your fridge. It can also be transferred to the unborn baby in a pregnant woman who is infected with the disease. Congenital dengue is an arboviral disease caused by four types of the dengue viruses (DENV 1-4). Congenital dengue can be dangerous if untreated. The disease can vary from mild to intense, and can take dangerous forms which include dengue shock syndrome and dengue hemorrhagic fever (DHF). DHF is also known as break bone fever.
