Can Dengue cause a more severe illness?
A Dengue infection can occasionally cause a more severe and potentially life-threatening illness associated with internal bleeding, Dengue Haemorrhagic Fever (DHF), or an illness associated with a sudden loss in blood pressure, Dengue Shock Syndrome (DSS). The risk of having these more severe types of Dengue infection is higher if someone has had a previous Dengue infection with a different virus strain.
