Dengue hemorrhagic fever

Dengue hemorrhagic fever is a severe clinical type of dengue fever. The onset is similar to typical dengue fever, and the condition suddenly worsens 2 to 5 days after the fever. Large-scale bleeding and shock occur in multiple organs, and blood concentration, thrombocytopenia, leukopenia, and liver enlargement occur. More common in adolescent patients, the mortality rate is higher. Dengue hemorrhagic fever was first detected in Thailand in 1950, and the epidemic occurred successively in Southeast Asia, the Pacific Islands, and the Caribbean. About 50 million to 100 million cases of dengue occur each year worldwide, and 500,000 of them progress to more severe dengue hemorrhagic fever and dengue shock syndrome.
