What is Dengue Fever?

Dengue is a mosquito-borne illness. It can be one of four types of DENV virus and is closely related to the viruses that cause yellow fever and the West Nile infection. It typically affects those who are living in tropical countries. Around 400 million infections occur every year. Dengue is a very severe and debilitating disease that requires immediate treatment and care.

Below is a graph that shows what takes place 4-10 days after the mosquito bite. Temperatures reach up to 40 C in the first 2 days of the febrile stage and then shock bleeding or organ impairment may occur in the critical stage. If the patient makes it through the critical stage, steady recovery is on the horizon as platelet count increases.

Only after Day 5 of symptom onset ( Fever ) we may check Dengue IgM antibody.
