In recent weeks, Dengue fever has started to spread in some areas. Every year, during the rainy season, stagnant water leads to the outbreak of Dengue fever, threatening public health, especially children.

The early rainy season is when dengue fever spreads rapidly and can easily escalate into outbreaks. Patients with dengue fever may self-treat and rest at home. However, warning signs such as bleeding gums, vomiting blood, and passing black stools require immediate hospital visits, as they indicate severe dengue.

The most dangerous stage of dengue fever usually occurs on the third to seventh day after the onset of fever. The patient may still have a fever, or the fever may have subsided, but the patient's physical condition is very weak, showing signs of restlessness, cold extremities, nosebleeds, bleeding gums, and bloody urine and stools.

Treatment of dengue fever requires timely and proper rehydration and electrolyte repletion to limit serious consequences caused by dehydration, such as shock, circulatory collapse, coma, and neurological disorders.

After about 7 days, children with dengue fever will show signs of recovery, including no fever, more frequent bowel movements, improved appetite, and improved clinical indicators

Annually, hemorrhagic Dengue fever becomes more prevalent during rainy months and peaks during October - November. Early signs are not highly specific and can be misdiagnosed. For how many days should a fever last before testing for hemorrhagic Dengue fever should be carried out?
