Dengue fever, or known as DBD, is a serious mosquito-borne disease that affects millions of people around the world each year. In Indonesia, DBD is a major public health concern, with thousands of cases reported annually. Understanding the clinical course of DBD is crucial in saving lives and preventing severe complications.

DBD typically progresses through three phases: febrile, critical, and recovery. The febrile phase is characterized by sudden onset of high fever, severe headache, muscle and joint pain, and rash. Patients may also experience nausea, vomiting, and abdominal pain. This phase usually lasts for 2-7 days.

As the disease progresses, some patients may enter the critical phase, which is marked by plasma leakage and severe bleeding. This phase usually occurs around the time the fever subsides, typically around days 3-7 of illness. Patients may develop signs of shock, such as rapid pulse, cold clammy skin, and low blood pressure. Severe bleeding can also occur, leading to hemorrhage and organ failure.

Early recognition of the critical phase is crucial in preventing fatalities. Patients who develop warning signs such as persistent vomiting, abdominal pain, restlessness, or bleeding should seek immediate medical attention. Timely intervention, such as fluid resuscitation and blood transfusion, can help stabilize the patient and prevent further complications.

After the critical phase, patients enter the recovery phase, where symptoms gradually improve and the body starts to recover. However, some patients may experience prolonged fatigue and weakness, which can last for weeks to months. It is important for patients to get plenty of rest, stay hydrated, and follow up with healthcare providers for monitoring and support.

In conclusion, understanding the clinical course of DBD is essential in saving lives and preventing severe complications. Early recognition of warning signs and timely intervention can help improve outcomes and reduce mortality. By raising awareness about DBD and educating the public about its clinical phases, we can work together to combat this deadly disease and protect our communities.
