Critical phase. Near the disappearance of fever, when the temperature drops to 37.5 degrees Celsius or less and remains below this level, usually in the first seven days of the disease, you can increase the capillary permeability in parallel and the Blood Test shows changed values .

This marks the beginning of the critical phase.

Patients who get worse by the fall of fever and show signs of alarm are things that need to be handled carefully from a clinical point of view.

There are certain problems that can occur in the critical phase of the disease, including severe bleeding or severe organ involvement, including the liver.

Recovery. When the patient survives the critical phase, which lasts no longer than 48 to 72 hours, he goes to the recovery phase, where he begins to improve the health of the infected person.

Dengue starts It can manifest as a non-specific febrile syndrome. In case of dengue fever, the patient presents severe abdominal pain, persistent vomiting, fluid retention, bleeding of the mucous membranes.
