<s>[INST] What Is The First Sign Of Dengue Fever? [/INST] Dengue symptoms can range from mild to severe. And some individuals, especially children and teenagers, may not exhibit any signs of the disease at the earliest. Gradually the symptoms start to appear four to seven days after being bitten by an infected mosquito. In its milder form, dengue presents as a High Fever (often around 104°F) accompanied by any of the following seven warning signs:

Headache
Muscle, bone, and joint pain
Nausea
Vomiting
Pain behind the eyes
Swollen glands
Rash
In rare and severe cases, the disease can progress to hemorrhagic fever, leading to damaged and leaky blood vessels, severe bleeding, a sudden drop in blood pressure, and even death. Source: DR.
