Dengue fever usually results in abrupt onset of high fever, headache, myalgias, arthralgias, and generalized lymphadenopathy, followed by a rash that appears with a 2nd temperature rise after an afebrile period. Respiratory symptoms, such as cough, sore throat, and rhinorrhea, can occur.
Liver involvement in acute dengue infection is frequently observed and sometimes leads to acute liver failure, with fatal outcomes. Many factors are thought to contribute to liver dysfunction, including hypoxic injury due to decreased perfusion, direct damage by the virus and immune mediated injury.
Complications and sequelae of dengue virus infections are rare but may include the following:
- Cardiomyopathy.
- Seizures, encephalopathy, and viral encephalitis.
- Hepatic injury.
- Depression.
- Pneumonia.
- Iritis.
- Orchitis.
- Oophoritis.
Plasma leakage is a process in which the protein rich, fluid component of the blood leaks from blood vessels into the surrounding tissue. Plasma leakage is the most serious complication that distinguishes dengue from severe dengue. For some dengue patients, as fever begins to disappear, severe dengue will develop.
Dengue Shock Syndrome (DSS) is defined as hypotension, narrow pulse pressure (£20 mm Hg), or frank shock in any case patient whose illness meets the criteria for DHF.
There is no medicine for treating dengue fever. Mild cases may be treated at home with rest and plenty of fluids to prevent dehydration . You may take acetaminophen (Tylenol) for pain. But don't take anti-inflammatory medicines like aspirin, ibuprofen (such as Advil or Motrin), or naproxen (such as Aleve).
A patient enters what is called the critical phase normally about 3-7 days after illness onset. It is at this time, when the fever is dropping (below 38°C/100°F) in the patient, that warning signs associated with severe dengue can manifest.
Based on the fact that the liver is one of the main organs affected by dengue35,36,37,38 and that lungs and heart are also important sites involved with the severe disease13,37,39,40,41, samples from all these three organs were considered.
Symptoms of dengue typically last 2–7 days. Most people will recover after about a week.
6. Increased Destruction of Platelets Causes Thrombocytopenia in Dengue. Thrombocytopenia may also be due to (1) platelet consumption during ongoing coagulopathy process, (2) activation of the complement system [113], or (3) increased peripheral sequestration [32, 114].
The explanation developed by the author is that because the heart is on the left side, the volume of the left lung is smaller than that of the right lung.
Some of the common symptoms of viral dengue fever include high fever, headache, body aches, weakness, joint pain, loss of appetite, cold and cough, nausea, vomiting and skin rashes and nose bleeding. Most patients suffering from dengue fever recover within two weeks.
This is when hospitalisation is indicated:If the patient is suffering from severe abdominal pain. If there is persistent vomiting, lethargy and restlessness. If there is an abrupt change from fever to hypothermia or a very low body temperature. If the patient begins to bleed or is looking pale.
Symptoms of Dengue Fever
- Sudden, high fever.
- Severe headaches.
- Pain behind the eyes.
- Severe joint and muscle pain.
- Fatigue.
- Nausea.
- Vomiting.
- Skin rash, which appears two to five days after the onset of fever.
When symptoms do occur, they may be mistaken for other illnesses — such as the flu — and usually begin four to 10 days after you are bitten by an infected mosquito. Dengue fever causes a high fever — 104 F (40 C) — and any of the following signs and symptoms: Headache.
Diet tips for dengue for fast recovery
- Foods to eat.
- Papaya leaf juice. Papaya leaf juice is a quite famous remedy for dengue fever.
- Vegetable juices. Vegetables are rich in essential nutrients.
- Coconut water. It is recommended to drink coconut water in dengue to avoid dehydration.
- Herbal tea.
- Neem leaves.
- Foods to avoid.
The primary form of Dengue Fever is characterized by a skin rash and a high fever with severe pain in the head and muscles. Other symptoms may include shaking chills, diarrhea, and vomiting. Bouts of extreme exhaustion may last for months after the initial symptoms.
Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4. For this reason, a person can be infected with a dengue virus as many as four times in his or her lifetime.
Myocarditis is an inflammation of the myocardium. Viral infection is one of the most common causes of myocarditis. Although rare, dengue has been reported to cause myocarditis.
Rash in dengue fever is a maculopapular or macular confluent rash over the face, thorax, and flexor surfaces, with islands of skin sparing. The rash typically begins on day 3 and persists 2-3 days. Fever typically abates with the cessation of viremia.
Yes, dengue can strike you again and again. You can get infected with dengue not once, twice but multiple times, with each subsequent infection being deadlier than the ones before.
There is no human-to-human dengue fever transmission. Once a mosquito is infected, it remains infected for its life span. A human can infect mosquitoes when the human has a high number of viruses in the blood (right before symptoms develop).
In general there are no long-term effects of dengue infection. On rare occasions, dengue may also appear as a severe and potentially fatal disease called dengue hemorrhagic fever (DHF). There is no vaccine to prevent dengue and no medication to cure it.
