How do you know if dengue is severe?

Warning signs of severe dengue

Belly pain, tenderness.
Vomiting (at least 3 times in 24 hours)
Bleeding from the nose or gums.
Vomiting blood, or blood in the stool.
Feeling tired, restless, or irritable.

What is recovery stage of dengue?

The phase of dengue beyond 6th day of illness is called recovery phase (though a sizable number of patients take longer to recover). When the dengue virus infects a previously non-infected person, it is inferred as primary dengue infection [PDI].

Which age group is more critical for dengue fever?

We showed that those at higher age are more likely to develop symptomatic dengue than younger individuals for both primary and secondary infections; the estimated proportion of symptomatic patients among the total number of infected individuals was below 7% for those aged younger than 10 years of age for both primary …

What is the critical platelet count in dengue?

A typical person has a platelet count of between 150,000 and 250,000 per microlitre of blood. About 80 to 90 per cent of patients with dengue will have levels below 100,000, while 10 to 20 per cent of patients will see critically low levels of 20,000 or less.

What are the stages of dengue fever?

Dengue begins abruptly after a typical incubation period of 5–7 days, and the course follows 3 phases: febrile, critical, and convalescent.

When should a dengue patient be hospitalized?

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.

What are the stages of dengue?

How many days it takes to recover platelets?

Mean spontaneous platelet recovery time was 3±2.6 days and 3±1.87 days in primary and secondary infection respectively. Higher platelet count at presentation was associated with early recovery time (p<0.033).

Who is most at risk for dengue?

You have a greater risk of developing dengue fever or a more severe form of the disease if: You live or travel in tropical areas. Being in tropical and subtropical areas increases your risk of exposure to the virus that causes dengue fever.

Who is most vulnerable to dengue fever?

DHF and DSS are life-threatening conditions requiring hospitalization and are believed to occur most frequently among children, the elderly, and those previously infected with at least one of four strains (DENV-1, DENV-2, DENV-3, DENV-4) of dengue virus.

What is the critical stage of 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.

What happens if platelet count is 50000?

The following platelet counts carry the risk of serious bleeding: Between 20,000 and 50,000 per μl: There is more risk of bleeding when injured. Less than 20,000 per μl: Bleeding happens even without injury. Below 10,000 platelets per μl: Spontaneous bleeding can be severe and a risk to life.
