Patient's question:
The baby is 3 years old this year. Yesterday, he suddenly had a high fever and kept having it off and on at night. Sometimes when the fever was severe, he also had nausea and vomiting. There has been a Dengue fever outbreak recently, so I'm a bit worried. I'd like to ask for some advice.Doctor's answer:
Dengue fever not only causes fever and vomiting but also symptoms such as rash, swollen lymph nodes, and muscle pain. If an infant is in an epidemic area and has been bitten by mosquitoes, showing symptoms of fever and vomiting, it is advisable to first monitor and provide symptomatic treatment. Specific diagnosis or medical examination may be required. It is recommended to conduct a blood routine examination and specific tests on the infant, including blood tests for dengue fever, as well as double serum complement tests, neutralization tests, or hemagglutination inhibition tests. A titer above 1:32 in a single serum complement test and a titer above 1:1280 in a red blood cell agglutination test. The serum double convalescent antibody titer can be diagnosed as being four times higher than in the acute phase. After dengue fever, white blood cell counts decrease and reach their lowest point on the 4th-5th day.
