Dengue Transmission

 

 Dengue can not be transmitted from person to person. Transmission is at its highest early in the morning and late at night. Below is a simple diagram to illustrate the transmission process:

 Symptoms 


Dengue fever has three phases. In phase one, infected individuals may experience flue like symptoms, sever headaches and aching in the joints and bone. Around a quarter of victims become very unwell and in a small proportion of cases it can be fatal.
