I want to know that if once I suffered from dengue, so is it possible to have dengue fever again, Is it right that if a person had dengue once he will not suffer it again. Is that correct.

No. Recurrence wit a different strin can occur ,many who suffer repeat infections have it worse. They come down with dengue hemorrhagic fever and suffer massive internal bleeding and liver damage. Oddly, the virus causing dengue fever comes in four strains, and immunity to one seems to make infection by a second strain more dangerous. The going theory for this--that antibodies generated by a first bout with dengue bind to a second strain, which helps it multiply in the immune cells--doesn't account for the internal bleeding and tissue damage,
