Dengue virus
Dengue virus is a mosquito-borne virus that can cause a severe flu-like illness. It is found in tropical and subtropical regions around the world, and is a major public health concern in many countries.

In severe cases, dengue virus can lead to dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). DHF is a life-threatening condition that can cause bleeding, organ failure, and death. DSS is a more severe form of DHF that can lead to shock and death.
