登革热可分为典型登革热（dengue fever，DF）、登革出血热（dengue hemorrhagic fever，DHF）和登革休克综合征（dengue shock syndrome， DSS）三种类型。
所有典型登革热患者均发热。起病急，先寒战，随之体温迅速升高，24小时内可达40℃。一般持续5～7日，然后骤降至正常，热型多不规则，部分病例于第3～5日体温降至正常，1日后又再升高，称为双峰热或鞍型热。儿童病例起病较缓、热度也较低。发热时伴全身症状，如头痛、腰痛，尤其骨、并节疼痛剧烈，似骨折样或碎骨样，严重者影响活动，但外观无红肿。消化道症状可有食欲下降，恶芯、呕吐、腹痛、腹泻。脉搏早期加快，后期变缓。严重者疲乏无力呈衰竭状态。患者于病程3～6日出现斑丘疹或麻疹样皮疹，也有猩红热样皮疹，红色斑疹，重者变为出血性皮疹。皮疹分布于全身、四肢、躯干和头面部，多有痒感，皮疹持续5~7日。疹退后无脱屑及色素沉着25～50%病例有不同程度出血，如牙龈出血、鼻衄、消化道出血、咯血、血尿等。其他 多有浅表淋巴结肿大。约1/4病例有肝脏肿大及ALT升高，个别病例可出现黄疸，束臂试验阳性。轻型登革热表现类似流行姓感冒，短期发热，全身疼痛较轻，皮疹稀少或无疹，常有表浅淋巴结肿大。因症状不典型，容易误诊或漏疹。
重型登革热 早期具有典型登革热的所有表现，但于3～5病日突然加重，剧烈头痛、呕吐、谵妄、昏迷、抽搐、大汗、血压骤降、颈强直、瞳孔散大等脑膜脑炎表现。有些病例表现为消化道大出血和出血性休克。登革出血热开始表现为典型登革热。发热、肌痛、腰痛，但骨、关节痛不显著，而出血倾向严重，如鼻衄、呕血、咯血、尿血、便血等。常有两个以上器官大量出血，出血量大于100毫升。有的病例出血量虽小，但出血部位位于脑、心脏、肾上腺等重要脏器而危及生命。登革休克综合征具有典型登革热的表现；在病程中或退热后，病情突然加重，有明显出血倾向伴周围循环衰竭。表现皮肤湿冷，脉快而弱，脉压差进行性缩小，血压下降甚至测不到，烦燥、昏睡、昏迷等。病情凶险，如不及时抢险，可于4～10小时内死亡。病程中还可出现脑水肿，预后严重。但如能及时正确处理，渡过危险期后可迅速恢复。登革热的发热特点是突然高热，发热持续5～7天后骤然退热，热退后1～2天体温可再度升高，这种发热称为双峰热或马鞍热。除发热的突出症状外，患儿在病程中可出现麻疹样皮疹或猩红热样皮疹。有的患儿可出现牙龈出血、鼻衄、咯血、尿血、消化道出血等表现。有的患儿会出现肝、脾和淋巴结肿大。重型登革热甚至会发生消化道大出血和出血性休克。

Generally continued for 5 to 7 days, and then plummeted to normal, hot and more irregular, some cases in the first 3 to 5 days to normal temperature, 1 day and then increased, known as bimodal heat or saddle type heat. Children with mild onset of disease, heat is also low. Fever with systemic symptoms, such as headache, low back pain, especially bone, and sections of severe pain, like bone or bone-like, severe affect the activities, but the appearance of no swelling. Digestive tract symptoms may have decreased appetite, evil core, vomiting, abdominal pain, diarrhea. Early pulse accelerated, late slowed down. Severe fatigue is unable to failure state.

Rash distributed in the body, limbs, trunk and head and face, more than itching, rash lasted 5 to 7 days. Rash back without scaling and pigmentation 25 to 50% of cases have different degrees of bleeding, such as gum bleeding, epistaxis, gastrointestinal bleeding, hemoptysis, hematuria and so on. There are many superficial lymph nodes. About 1/4 cases of liver enlargement and ALT increased, individual cases may occur jaundice, beam arm test positive. Light dengue fever is similar to the popular name of a cold, short-term fever, systemic pain, rash or rash, often superficial lymph nodes. Due to atypical symptoms, easy to misdiagnosis or lashes.
Heavy dengue fever has a typical performance of typical dengue fever in the early stage, but sudden increase in severe symptoms such as severe headache, vomiting, delirium, coma, convulsions, sweating, blood pressure, neck stiffness, and dilated pupils. Some cases showed gastrointestinal bleeding and hemorrhagic shock. Dengue hemorrhagic fever began to show typical dengue fever. Fever, myalgia, low back pain, but bone, joint pain is not significant, and bleeding tendency is serious, such as epistaxis, hematemesis, hemoptysis, hematuria, blood in the stool and so on. Often more than two organs of a large number of bleeding, bleeding is greater than 100 ml. Some cases of bleeding is small, but the bleeding site in the brain, heart, adrenal glands and other vital organs and life-threatening. Dengue shock syndrome has a typical performance of dengue fever; in the course of disease or fever, the condition suddenly increased, there is a clear tendency to bleeding with peripheral circulatory failure. The performance of the skin wet and cold, fast and weak pulse, pulse pressure difference is reduced, blood pressure or even undetectable, irritability, lethargy, coma and so on. Dangerous condition, if not timely rescue, can be 4 to 10 hours of death. Course of cerebral edema can also occur, the prognosis is serious. But if timely and correct treatment, through the dangerous period can be quickly restored. Dengue fever is characterized by sudden fever, fever for 5 to 7 days after the sudden fever, heat back 1 to 2 days body temperature can rise again, this heat is called bimodal heat or saddle fever. In addition to the prominent symptoms of fever, the children may be in the course of measles-like rash or scarlet fever-like rash. Some children may have bleeding gums, epistaxis, hemoptysis, hematuria, gastrointestinal bleeding and other performance. Some children will appear liver, spleen and lymph nodes.
