In our country, dengue fever is very common, the cause of the disease is Dengue virus. The disease usually breaks out in the rainy season every year when mosquitoes thrive.
The main vector of dengue fever is the Aedes aegypti mosquito. When a mosquito bites and transmits the virus to the body, the infected person will go through a certain period of time called the asymptomatic incubation period before showing the dangerous phase of dengue fever. So how many days does dengue fever incubation?
Incubation is the time when the body produces antibodies to fight the dengue virus. It is only when the amount of these antibodies is not produced to fight the virus that the symptoms of dengue fever manifest.
According to research, the incubation period of dengue fever lasts about 4 to 7 days, in many cases up to 14 days. However, the incubation period of dengue virus can vary, be shorter or longer, depending on factors such as the patient's location, resistance to the virus or the patient's age...
At the stage Incubation, tests are difficult to diagnose Dengue virus or another common viral flu.
The incubation period is asymptomatic, which can be long, so many patients are not detected but still lead normal activities. This inadvertently helps the virus spread to the community, infecting people with disease and healthy people, causing a violent outbreak.

4. Common mistakes when getting dengue fever
4.1. Subjective psychology
Dengue hemorrhagic fever is divided into 3 levels as mild, with warning signs and severe. Some mild patients can be treated on an outpatient basis, but regular follow-up visits are required by the doctor's appointment because the severity can change at any time.
Dengue hemorrhagic fever has warning signs and severe dengue requires hospitalization for treatment and close monitoring. Therefore, if the patient is being treated as an outpatient or has been diagnosed with Dengue hemorrhagic fever, there should be no subjective psychology but a follow-up appointment with the doctor to promptly detect serious complications and appropriate treatment.

Dengue virus has up to 4 serotypes, denoted D1, D2, D3, D4 and each type has the same ability to cause disease. Immunity formed after viral infection only has a preventive effect on each individual type.
Therefore, it is theoretically possible for a person to have multiple dengue infections in a lifetime caused by different types.
Dengue fever is a dangerous disease with different symptoms. Accordingly, the disease is even more dangerous when the fever is gone, which is also when the disease is at its most dangerous stage.
