Febrile phase
- Sudden high fever.
- Skin redness or red patches on the skin.
- Severe headache.
- Pain behind the eyes.
- Severe joint and muscle pain.
- Nausea.
- Vomiting.
- Easy bruising and bleeding.
Also, can dengue be detected on first day of fever? Dengue nonstructural protein 1 (NS1) is an antigen produced in abundance by the replicating dengue virus as early as the first day of symptoms and as late as day 18 of symptoms. NS1 can be detected in the blood sooner than IgM, which cannot be reliably detected until days 6 to 10.
Hereof, what is critical phase in dengue?
The critical phase of dengue begins at defervescence and typically lasts 24–48 hours. Most patients clinically improve during this phase, but those with substantial plasma leakage can, within a few hours, develop severe dengue as a result of a marked increase in vascular permeability.
How long does it take to recover from dengue fever?
Patients with uncomplicated Dengue fever usually recover completely in 10-15 days. But generalized weakness may persist for few days to weeks. Patients with Dengue haemorrhagic fever and Dengue shock syndrome take a longer time to recover and they may need intensive care.
What is the last stage of dengue?
The course of infection is divided into three phases: febrile, critical, and recovery. The febrile phase involves high fever, potentially over 40 °C (104 °F), and is associated with generalized pain and a headache; this usually lasts two to seven days.Does dengue need hospitalization?
For people who get sick with dengue, symptoms can be mild or severe. Severe dengue can be life-threatening within a few hours and often requires hospitalization.What is the first sign of dengue fever?

In moderate DHF cases, all signs and symptoms abate after the fever subsides. In severe cases, the patient's condition may suddenly deteriorate after a few days of fever; the temperature drops, followed by signs of circulatory failure, and the patient may rapidly go into a critical state of shock.When should we check platelets in dengue?
Senior physician Atul Joshi of Sahyadri Hospital said, "Even though fever subsides, patients should continue to monitor platelet count till the drop in count stops. Platelet count below 20,000 has higher chances of developing bleeding complication as seen in dengue haemmorrhagic fever."Is Dengue transmitted by kissing?
This injection of saliva infects the host with the dengue virus. Are mosquito bites the only way the dengue virus can be transmitted to humans? In rare events, dengue can be transmitted during organ transplantations or blood transfusions from infected donors.Can dengue be cured at home?
Juice of Papaya Leaves Another very effective remedy is drinking papaya leaf juice. Papaya leaves are known to be the natural cure for dengue fever. The leaves have a mix of nutrients and organic compounds which help in increasing your platelet count.What are the warning signs of dengue?
Warning Signs*- Abdominal pain or tenderness.
- Persistent vomiting.
- Clinical fluid accumulation.
- Mucosal bleed.
- Lethargy or restlessness.
- Liver enlargement > 2 cm.
- Laboratory finding of increasing HCT concurrent with rapid decrease in platelet count.
How high is the fever in dengue?
When symptoms do occur, they usually begin four to seven days after you are bitten by an infected mosquito. Dengue fever causes a high fever — 104 F degrees — and at least two of the following symptoms: Headache.How do you test for dengue?
Two primary types of testing are available: Molecular testing (polymerase chain reaction, PCR)—this type of test detects the genetic material of the dengue virus in blood within the first week after symptoms appear (fever) and can be used to determine which of the 4 serotypes is causing the infection.What is shock in dengue?
Dengue shock syndrome: A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock). Most deaths occur in children. Infants under a year of age are especially at risk of death.When can you expect Defervescence to occur during the clinical course of dengue?
Defervescence usually occurs on days 3 to 8 of illness when temperature drops to 38°C or less and remains below this level. Patients may have warning signs, mostly as a result of plasma leakage (Table 1).What are the preventive measures of dengue?

How do you do a tourniquet test?

- Inflate the cuff to a point midway between SBP and DBP and maintain for minutes. (
- Reduce and wait 2 minutes.
- Count petechiae below antecubital fossa.
- A positive test is 10 or more petechiae per 1 square inch.
