Consider the following statements: 1. Dengue is a protozoan disease transmitted by mosquitoes. 2. Retro-orbital pain is not a symptom of Dengue. 3. Skin rash and bleeding from nose and gums are some of the symptoms of Dengue. Which of the statements is/are correct?

Statement 1 is incorrect: dengue is caused by the dengue virus (a flavivirus), not a protozoan, and is transmitted by Aedes mosquitoes [1]. Statement 2 is incorrect: retro‑orbital pain (pain behind the eyes) is a well‑recognized symptom of dengue infection and is commonly listed among its presenting features [2]. Statement 3 is correct: dengue often presents with skin manifestations such as a maculopapular rash, and bleeding manifestations (including petechiae or bleeding from the nose and gums) can occur, particularly in more severe forms and dengue hemorrhagic fever [2]. Therefore, only statement 3 is correct.
