Suspicious information:
One of the misunderstanding about dengue fever from the Deng virus Is the belief that the illness of dengue fever will cause the patient to be immune to the dengue virus for the rest of their lives
Conclusion:
1. Dengue fever from the Deng Ki virus can be repeated because there are 4 species.
2. The second dengue illness is more intense than the first time. From the ADE phenomenon
3. Currently, there are 2 types of dengue vaccines.
4.QDENGA developed by Thai people Can inject either people who have been addicted or never infected
Fact Check: Examination of facts:
The Deng Ki virus has 4 species.
Deng how many or dengue fever is an infectious disease which is spread in the tropics. Caused by the infection of the Deng Ki virus, can be divided into 4 species or 4 Seotypes, including

2.DENV-2
3.DENV-3
4.DENV-4
How many species of Deng Virus Will make the patient immune to the infection of the Deng virus, that species for life, but will have the immune system to the Deng Virus, many other species, only temporarily
Therefore, the infection of the dengue virus and dengue fever Unable to prevent dengue fever in the future If there is a varieties of Deng Virus infected, the body has never been infected before.
Seriously illness from the ADE phenomenon
In addition, how many second round of the virus infection is infected? May lead to a phenomenon called “Acceleration of antibodies” or Antibody Dependent Enhancement (ADE), which is much more dangerous than the first infection.
The ADE phenomenon occurs when the antibodies that exist in the body do not inhibit virus infection. But instead helps the virus enter the patient’s cells more easily Causing the virus to divide more Resulting in more severe illness and life -threatening
