What are the characteristics of dengue patients

Dengue fever is an acute infectious disease caused by the dengue virus, which is mainly transmitted through mosquito bites. Patients usually have symptoms such as fever, rash, muscle aches, and some have a tendency to bleed.

1. Symptoms: The typical symptoms of dengue fever are sudden onset, high fever can reach 39-40 °C, accompanied by headache, fatigue, muscle, bone and joint pain, etc. Gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea may also occur.The rash is more common on the trunk and proximal extremities and presents as a maculopapular or morbilliform rash, often with pruritus. There are also some patients who have bleeding tendencies, such as nosebleeds, bleeding gums, etc.;

2. Signs: In addition to the above symptoms, there can also be signs such as hepatosplenomegaly and lymphadenopathy. In severe cases, complications such as shock, meningitis, and myocarditis may occur;

3. Diagnosis: Dengue fever can be preliminarily diagnosed according to the epidemiological history and clinical manifestations. The diagnosis needs to be judged in combination with the results of laboratory tests, including routine blood tests, C-reactive protein tests, serological tests, etc. Among them, serological examination is one of the most reliable diagnostic methods, which can determine dengue virus infection by detecting specific IgM antibodies in the blood;

4. Treatment: Dengue fever is a self-limiting disease and generally does not require special treatment.For patients with more severe disease, they need to be treated with antiviral drugs, such as oseltamivir phosphate granules, under the guidance of a doctor.

Pay attention to personal hygiene in daily life and avoid mosquito bites. If you have uncomfortable symptoms, you should seek medical attention in time and actively cooperate with the doctor for treatment.
