Clinical Utility

Dengue hemorrhagic fever and Dengue shock syndrome are caused by infection of the RNA flavivirus transmitted by a mosquito vector. Paired acute and convalescent specimens that exhibit a significant change in titer are useful to confirm clinical diagnosis of infection.

This is a reportable disease. All confirmed cases of dengue will be reported to the Oakland County Health Department.
