I suffered from dengue, can i donate blood?

Yes,but how long ago: The answer is yes- however only after you are absolutely and fully recover from it. If you had it more than 2 months ago- you should be fine. However it will be up to local blood bank discretion to accept you or not.If you're in endemic area- due to possibility of delay in appearance of dengue symptoms, and no good test for the illness- some blood banks would not accept donation for safety reason.

American Red Cross: recommends deferring blood donations for 6 months if you have had Dengue Fever. “In most countries, donors who have been infected with dengue virus are deferred for periods of up to 6 months or even longer if they have received blood transfusions.” REF: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2713854/ REF: http://www.americanredcrossblood.org/faq.html
