<s>[INST] What are the symptoms of dengue? What does dengue cause? [/INST] Infection with dengue viruses produces an array of clinical illness ranging from a nonspecific viral set of symptoms to a severe and fatal hemorrhagic (bleeding) disease. Three to 14 days after infection, people suddenly experience high fever, severe frontal headache, pain behind the eyeball, and joint and muscle pain; many experience nausea and vomit. A rash may appear 3-5 days after onset of fever and can spread from the torso to the arms, legs, and face. Most people recover completely within two weeks.

Others develop severe bleeding problems. This complication is called dengue hemorrhagic fever (DHF), and can be fatal if untreated. Source: TEXAS HEALTH AND HUMAN SERVICES. Link: https://www.dshs.texas.gov/mosquito-borne-diseases/dengue/dengue-faqs. Field: Infectious Disease. Disease: Dengue </s>
