  Dengue is a mosquito-transmitted virus, and dengue fever is the leading cause of arthropod-borne viral disease worldwide, posing a significant global health concern. This disease is also known by various monikers, such as breakbone or 7-day fever, and is characterized by intense muscle spasms, joint pain, and high fever, reflecting both the severity and the duration of symptoms. […] Although most dengue fever cases are asymptomatic, severe illness and mortality can occur. […] The typical incubation period for the disease is 4 to 7 days, with symptoms lasting from 3 to 10 days. Symptoms appearing more than 2 weeks after exposure are unlikely to be attributed to dengue fever. […] The presentation of dengue fever, whether asymptomatic, typical, or severe, is influenced by a complex interplay of host and viral factors. Severe dengue fever, characterized by heightened microvascular permeability and shock syndrome, is often associated with infection by a second dengue virus serotype and the patient’s immune response. However, severe cases of dengue fever can also arise from infection by a single serotype.

  Dengue fever can cause fever, headaches, rashes, and pain throughout the body. Although it can be very painful, it’s usually not fatal. Most people who get it start feeling better after several days and recover fully in a couple of weeks. […] Dengue fever used to be called „breakbone fever” because of the severe bone and muscle pain it sometimes causes. While the fever does not break any bones, it can sometimes feel like it does. […] A person with dengue fever may notice: a high fever, pain behind the eyes, pain in the joints, muscles, and/or bones, a severe headache, a rash over most of the body, easy bruising. […] Some people can get a more serious form of the infection called dengue hemorrhagic fever. They’ll have the regular symptoms of dengue fever for a few days. After the fever goes down, they also might have these problems: nausea and vomiting, severe belly pain, trouble breathing, bleeding from the nose or gums, vomiting blood, or blood in their stool (poop).

  Dengue is transmitted by the bite of an infected mosquito. It is an illness that affects infants, young children, and adults, with symptoms ranging from mild fever to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. The illness can evolve to severe dengue, characterized by shock, respiratory distress, severe bleeding, and/or serious organ impairment. […] The infection may be asymptomatic, or it may present with symptoms ranging from a moderate fever to a disabling high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rashes. The disease can evolve into severe dengue, characterized by shock, shortness of breath, severe bleeding and / or complications in the organs. […] Patients develop a sudden, high fever. This acute febrile phase lasts from 2 to 7 days and is usually accompanied by facial flushing, erythema, generalized body pain, myalgia, arthralgia, headache, and retro-ocular pain. Minor hemorrhagic manifestations such as petechiae and skin ecchymoses may occur. Patients who improve after the fever subsides are considered dengue cases without warning signs.

• #7 Dengue Fever: Causes, Symptoms & Treatment

  Dengue fever is an illness spread by the bite of mosquitos infected with one of the dengue viruses. Symptoms are usually flu-like but can worsen to severe dengue (dengue hemorrhagic fever), a life-threatening condition. Getting infected a second time increases your risk of serious symptoms. […] Symptoms of dengue are rash, eye pain, nausea or vomiting and muscle pain. If you live in or are visiting an area where dengue is common, seek medical attention immediately if you have warning signs of severe dengue. This includes abdominal pain, blood in your vomit or poop, bleeding gums or nose, frequent vomiting or extreme tiredness or restlessness. […] Most dengue infections dont cause symptoms. If you do have symptoms, high fever (104F/40C) is typical, along with: Rash. Intense pain behind your eyes. Nausea or vomiting. Muscle, bone and joint pain.

  Dengue causes flu-like symptoms and lasts for 2-7 days. Dengue fever usually occurs after an incubation period of 4-10 days after the bite of the infected mosquito. […] High Fever (40 C/104 F) is usually accompanied by at least two of the following symptoms: headaches, pain behind eyes, nausea, vomiting, swollen glands, joint, bone or muscle pains, rash. […] Individuals infected for the second time are at greater risk of severe dengue. When developing into severe dengue, the critical phase takes place around 3-7 days after the first sign of illness. […] On the other hand, special attention needs to be given to these warning signs as it could lead to severe dengue: severe abdominal pain, persistent vomiting, bleeding gums, rapid breathing, fatigue/restlessness, blood in vomit or stool, being very thirsty, pale and cold skin. […] Severe dengue can cause: plasma leaking that may lead to shock and/or fluid accumulation with/without respiratory distress; severe bleeding; and severe organ impairment. […] For people with severe dengue, hospitalization is often needed.

  https://dndi.org/diseases/dengue/facts/

  Dengue symptoms range from none to serious flu-like symptoms. A small proportion of people develop severe dengue, which can be fatal. […] Dengue can have no symptoms or cause only mild illness, but it can also cause flu-like symptoms such as: high fever (40C/104F), severe headache, pain behind the eyes, nausea, vomiting, swollen glands, rash, muscle, joint, or bone pains so severe that dengue is sometimes referred to as breakbone fever. […] Severe dengue happens when blood vessels become damaged and leaky, and the number of platelets (cells which form clots) drops. As a result, severe dengue can cause shock, internal bleeding, bleeding gums or nose, organ failure, and death. The symptoms of severe dengue include: severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums or nose, fatigue, restlessness, liver enlargement, blood in vomit or stool, potentially fatal. […] The lack of treatment options increases the risk of people developing severe dengue, which is potentially fatal.

• #10 Dengue Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/215840-clinical

  Patients with dengue will have a history of living in, or recent travel to, a region where the disease is endemic. The incubation period is 3-15 days (average, 4-7 days); symptoms that begin more than 2 weeks after a person departs from an endemic area probably are not due to dengue. […] Many patients experience a prodrome of chills, erythematous mottling of the skin, and facial flushing (a sensitive and specific indicator of dengue fever). The prodrome may last for 2-3 days. Children younger than 15 years usually have a nonspecific febrile syndrome, which may be accompanied by a maculopapular rash. Classic dengue fever begins with sudden onset of fever, chills, and severe (termed breakbone) aching of the head, back, and extremities, as well as other symptoms. The fever lasts 48-96 hours and may reach 41C. Fever that lasts longer than 10 days probably is not due to dengue.

  Dengue fever usually results in abrupt onset of high fever, headache, myalgias, arthralgias, and generalized lymphadenopathy, followed by a rash that appears with a recurrent fever after an afebrile period. […] After an incubation period of 3 to 15 days, fever, chills, headache, retro-orbital pain with eye movement, lumbar backache, and severe prostration begin abruptly. Extreme aching in the legs and joints occurs during the first hours, accounting for the traditional name of breakbone fever. The temperature rises rapidly to up to 40 C, with relative bradycardia. Bulbar and palpebral conjunctival injection and a transient flushing or pale pink macular rash (particularly of the face) may occur. Cervical, epitrochlear, and inguinal lymph nodes are often enlarged. […] Fever and other symptoms persist 48 to 96 hours, followed by rapid defervescence with profuse sweating. Patients then feel well for about 24 hours, after which fever may occur again (saddleback pattern), typically with a lower peak temperature than the first. Simultaneously, a blanching maculopapular rash spreads from the trunk to the extremities and face.

  Dengue is a mosquitoborne viral infection found across much of the tropical and subtropical world. Most infections are asymptomatic or paucisymptomatic. Acute symptoms range from an influenza-like self-limited febrile illness to, in a small proportion of cases, severe and complicated disease that can prove fatal. The symptoms of acute dengue are generally understood to resolve after 12 weeks, but the potential for persistent or delayed symptoms has received increasing attention in recent years. However, few formal studies have been published, and these studies have reported a range of symptoms and frequencies. A recent review summarizing this literature showed a substantial proportion of persons experienced some kind of postacute symptoms; the proportion decreased over time after infection, and 24% reported notable fatigue.

  Dengue is an arboviral infection clinically recognized as an acute and self-limited disease. Persistence of dengue symptoms is known, but it has been little studied. Symptoms that persisted for more than 14 days were observed in 61 (54.0%) patients, and six (6.2%) of them had symptoms for 6 months or more. The persistent symptoms identified were myalgia, weakness, hair loss, memory loss, reduced resistance to physical effort, headache, reasoning problems, arthralgia, sleepiness- and emotional lability. […] The progression to persistent symptoms was significantly associated with hospitalization, older age, more severe disease, the presence of bleeding and comorbidities upon univariate analysis. Upon multivariate analysis, the presence of persistent symptoms continued to be significantly associated only with increased age and dengue with warning signs. […] In conclusion, the frequency of progression to persistent symptoms in dengue is relevant in patients seen at a tertiary hospital and the persistence of symptoms is more common in patients with dengue with warning signs.

  We report on postinfectious symptoms in 247 predominantly pediatric patients from Vietnam 3 months after an acute febrile illness; 200 of them had dengue. After acute dengue, we observed a broad spectrum of postviral symptoms ranging from fatigue, joint pain, and muscle pain to vision problems and hair loss. We report 8% patients experienced fatigue, consistent with a study in Singapore reporting 9%, but lower than the 24% in another Singapore study and the 28% reported from Cuba. Our estimate of 47% of persons experiencing 1 symptom is higher than the 8.5% observed in Peru but lower than the 65% experiencing 1 persistent symptom observed in Brazil. […] The alopecia we report in our study has been observed previously, at a much lower rate in 1 study in Brazil and at a similar rate in a recent study from Mexico. Alopecia after dengue has been noted in 1 case report. Vision problems associated with dengue have previously been reported but mainly during the acute phase or soon afterwards. In our study, we saw that these symptoms can persist for several months or start much later after infection, which was also seen in the recent study in Mexico.

  Recovery is complete but slow, with fatigue and exhaustion often persisting after the fever has subsided. The convalescent phase may last for 2 weeks. […] Patients are at risk for development of dengue hemorrhagic fever or dengue shock syndrome at approximately the time of defervescence. Abdominal pain in conjunction with restlessness, change in mental status, hypothermia, and a drop in the platelet count presages the development of dengue hemorrhagic fever. […] Of patients with dengue hemorrhagic fever, 90% are younger than 15 years. The initial phase of dengue hemorrhagic fever is similar to that of dengue fever and other febrile viral illnesses. Shortly after the fever breaks (or sometimes within 24 hours before), signs of plasma leakage appear, along with the development of hemorrhagic symptoms such as bleeding from sites of trauma, gastrointestinal bleeding, and hematuria. Patients may also present with abdominal pain, vomiting, febrile seizures (in children), and a decreased level of consciousness.
