Question

Quizplus · Accepted Answer

Dengue virus is an arbovirus that causes a disease sometimes known as "break bone fever" because of the muscle and joint pain associated with it. Infection by a different virus serotype following a primary infection causes a more serious disease that is thought to be due to the enhancing effect that antibodies to the initial virus have on the second virus's infection properties.
