It is easy to confuse the typical symptoms of dengue with the symptoms of other tropical diseases. So, how can you tell the difference between dengue, Chikungunya, malaria, Zika or other viruses like flu or even COVID-19?  

Dengue, Chikungunya and Zika are caused by viruses that can be passed on by the same type of mosquito, which usually bites during the day. Malaria is also transmitted by mosquitoes but is caused by parasites. These diseases can all cause a range of symptoms that may include fever, headaches, muscle, and joint pain.
