1. How dangerous is dengue fever?
Dengue fever is a common disease in Vietnam, due to the tropical monsoon climate, dengue fever easily spreads to the community, especially the southern and central provinces with hot and humid characteristics all year round. Dengue hemorrhagic fever is a disease caused by infection with the dengue virus, transmitted by the Aedes aegypti mosquito, also known as the midges mosquito. This disease has been recorded since the 13th century with the number of cases continuously increasing over time.
This is also a disease classified by WHO as a dangerous infectious disease of concern because it has occurred in more than 100 countries with the number of infections reaching 50-1000 cases per year.
This disease is trending more commonly in Asian countries and is even considered the leading cause of infectious diseases leading to hospitalization or death in this region.
Dengue fever is transmitted to healthy people by the bite of Aedes aegypti mosquito. This is a type of mosquito that often bites people during the day and they do not naturally carry the dengue virus by themselves, but because they bite an infected person and then transmit it to other healthy people.
Currently, there is no effective vaccine for dengue fever. Medicine is still in the research process to find a specific vaccine to prevent this disease. Currently, there are no specific drugs or treatments for this disease, treatment mainly includes monitoring and care activities as well as supporting necessary functions for the body. .

If there is a suspicion of dengue fever, it is necessary to take the patient to medical centers for Dengue NS1 Ag test immediately. If the patient receives a positive result, it is certain that the patient has dengue fever and needs prompt treatment.
Stage 2: The next stage is a very dangerous stage, during which severe symptoms of dengue fever begin to be noticed. This phase usually starts from the 3rd to the 7th day from the time of fever.
At this time, the patient may have had a fever but still have symptoms such as bleeding under the skin, nosebleeds or bleeding gums. Subcutaneous hemorrhages often appear on the front of the legs, the inside of the arms, abdomen, thighs...

3. What tests should be done when having dengue fever?
When dengue fever is suspected, it is necessary to take the patient for testing to identify the disease early and have timely treatment.
Vinmec International General Hospital always has tests to identify dengue fever. Those are Dengue virus NS1 Ag test and blood count test. The test to determine the existence of Dengue virus helps doctors diagnose whether a patient has dengue fever or not, thereby having a timely treatment plan to ensure the patient's health.
Besides, the patient also needs to have a complete blood count test to determine the number of red blood cells, platelets, and white blood cells. In particular, the platelet count is very important in the diagnosis and treatment of dengue fever. If the platelet count drops sharply, the patient needs to be hospitalized for treatment and monitoring, and if the platelet count is low, the patient can be sent home for further monitoring.
