When a mosquito carrying the virus bites a person, the virus with the mosquito’s saliva goes in to the skin, then comes in to white blood cells, and multiplies and moves throughout different body parts. Diagnosis of dengue is usually done clinically especially when the patient possesses the symptoms listed and has underwent physical examination. It has been advised that one may be suspected with the dengue virus if he or she has already developed fever for two weeks or so.
