dengue virus
Dengue cases are currently increasing in many states of the country. Among the dengue cases that are coming, there are many patients who had dengue last year and it happened this time too. There are even such cases in which people have contracted dengue for the third time in their lifetime. In such a situation, it is important to know why this is happening again and again to the same person. Whereas after immunity is formed against a virus, the chances of its recurrence are less. Every year we know about the causes of dengue from experts.
Dr. Kuldeep Kumar, Professor in the Department of Medicine, GTB Hospital, Delhi. show that in some patients dengue It happens even twice a year. The reason for this is that there are four different strains of dengue virus. These are called DENV-1, DENV-2, DENV-3 and DENV-4. When a person is infected with a strain for the first time, his body becomes immune against that strain, but if a person gets infected with another strain for the second time, he gets dengue again. However, if you get dengue twice, the risk of a serious condition may increase.
Is weak immunity also the reason?
Dr. Kuldeep says that having dengue repeatedly does not mean that a person’s immunity is weak. This is directly related to the strain of dengue. Even if immunity has been formed against one strain, if the mosquito bites you for the second time and there is another strain of this virus in it, then you will get dengue. Although not every person gets serious symptoms the second time, but if you have been infected then it is important to consult a doctor. Do not be careless in this matter. In such cases, doctors can do blood tests and antibody tests, which can reveal which strain is active in the body and which has produced antibodies. Treatment is done accordingly.
