What are the symptoms of dengue fever?

Dengue fever is a mosquito-borne infectious disease characterized by a range of symptoms and clinical manifestations.

Fever and petechial rash are common symptoms, often accompanied by myalgia, asthenia, nausea, vomiting, anorexia, abdominal pain, and diarrhea.
Headache, muscle and joint pains, and a characteristic skin rash similar to measles are typical, with severe cases potentially developing into dengue hemorrhagic fever or dengue shock syndrome.
Dengue hemorrhagic fever often presents with fever, headache, myalgia, arthralgia, retro-orbital pain, vomiting, abdominal pain, and various bleeding manifestations, including shock syndrome in some cases.
Ocular manifestations such as subconjunctival, vitreous, and retinal hemorrhages, posterior uveitis, optic neuritis, and maculopathies can occur, leading to symptoms like blurred vision and floaters.
Gastrointestinal symptoms like nausea, diarrhea, and hyponatremia are notably prominent in some outbreaks, especially among immunologically naïve adults.
A significant proportion of patients with dengue fever experience abdominal and gastrointestinal symptoms, with nausea and abdominal pain being the most frequent; these symptoms are more common in hospitalized patients.
Additional symptoms reported during epidemics include dizziness, weakness, bleeding tendencies, and hair loss occurring post-recovery.
Classical symptoms of dengue such as fever, headache, and myalgia are consistent, with digestive symptoms and hemorrhagic manifestations also prevalent; shock occurs in a substantial number of severe cases.

In conclusion, dengue fever presents with a wide array of symptoms, predominantly fever, rash, and muscle pain, but can also include significant gastrointestinal involvement and, in severe cases, hemorrhagic complications and shock. Ocular symptoms and post-recovery hair loss are less common but notable features of the disease.
