Dengue symptoms. Top 10 symptoms

Dengue virus is the cause of dengue fever. It is a mosquito-borne single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease. At its beginning stage it is not easily recognized, because its symptoms are quite similar to the symptoms of malaria and flue. But at its peak stage, the symptoms are quite different as pain behind eyes, abdominal pain, rashes and mild bleeding. Here are the symptoms of Dengue fever with detail. One should be aware of these symptoms so that immediate treatment be made. 

  • Sudden, high fever:

    Symptoms of dengue usually develop suddenly 4 to 10 days after becoming infected. Symptoms can include: a high temperature (fever), which can reach 40C (104F) or higher. Extreme fever is the foremost symptom of dengue fever.

  • Severe headaches:

    The patient feels severe headache during the fever. The disease manifests as a sudden onset of severe headache, chills, pain upon moving the eyes, and low backache. … There may also be gastritis with some combination of associated abdominal pain, nausea, vomiting, or diarrhea.

  • Pain behind the eyes:

    Besides the headache patient also suffers from severe pain in the behind of eyes. This pain also cause mild bleeding through the nose. Patient should use paracetamol to relieve the pain and avoid Ibuprofen because Ibuprofen can cause more bleeding.

  • Severe joint and muscle pain:

    Pain is the foremost symptom of dengue fever. Severe pain is felt all through the body. But pain in joints, muscles, headache, pain behind the eyes is extremely high. In dengue, myalgia or muscle pain is prominent. A patient with chikungunya has a more severe form of joint pain and arthritis that sometimes goes on for months and can be crippling. Patients with compromised immune system such as diabetics or those taking drugs like immunosupressants, or suffering from chronic ailments of liver and kidneys, compromised respiratory function are prone to suffer from severe form of disease. The pain in muscles and joints remain for months after the relief from fever. Many of the patients complained of pain even after the fever for several days and even months. Orthopedist suggests that vitamin D and E helps relieving pain.

  • Abdominal Pain:

    Abdominal pain is a commonly reported symptom in Dengue Fever. The reported causes of abdominal pain in DF include hepatitis, pancreatitis, Acaculous cholecystitis and peptic ulcer disease. Till to date, there has been no planned study to evaluate the cause of pain in abdomen in Dengue Fever. This study was planned to evaluate the etiology of abdominal pain in Dengue Fever.  A probable diagnosis of Dengue Fever was made based on the presence of acute febrile illness with two or more of the following manifestations: headache, retroorbital pain, myalgia, arthralgia, rash, haemorrhagic manifestation and leukopenia. The diagnosis was confirmed by enzyme immunoassay-based serology. Dengue High Fever was diagnosed based on WHO criteria. The cause of pain in abdomen was ascertained by blood tests (amylase, lipase and liver function test), radiology (X-ray abdomen-erect and supine, USG, CECT) and/or endoscopy.
    Out of the 100 patients presenting with fever and pain abdomen, 55 patients were diagnosed to
    have Dengue Fever. The remaining 45 patients had other causes of fever with pain abdomen. The various causes of pain abdomen diagnosed in patients with DF were: acute hepatitis, acalculus cholecystitis, acute pancreatitis, appendicitis, spontaneous bacterial peritonitis, enteritis, peptic ulcer disease and gastric erosions in 20 (36.4%), 9 (16.4%), 8 (14.5%), 3 (5.45%), 2 (3.63%), 8 (14.54%), 2 (3.63%) and 3 (5.45%) of the patients respectively.
    In patients with dengue fever, the etiology of abdominal pain should be aggressively looked into for
    proper management.

  • Fatigue:

    Although the acute manifestations of dengue are well known, few studies have assessed the long-term consequences of dengue infection. We prospectively studied the incidence and factors associated with fatigue in a cohort of patients following dengue infection.

  • Nausea:

    Patient of Dengue Fever feels severe Nausea like in malaria. Nothing is properly swallowed by patient. Process of antiperistalsis starts and patient vomits whatever he/she takes as medicine.

  • Vomiting:

    Vomiting is the result of Nausea. Whatever swallowed is abruptly vomited. This is a dangerous situation which intensifies the process of dehydration. Note that in Dengue Fever diarrhea completely dehydrates the body of patient. Vomiting adds fuel to dehydration. This is a fatal condition.

  • Skin rash

    Which appears two to five days after the onset of fever. 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.

  • Mild bleeding:

    Bleeding from nose, gums and under the skin is the symptom of Dengue Fever. Ibuprofen and Aspirin should be avoided as these medicine can increase the bleeding. Only paracetamol should be used to relieve the pain.
