Every year, increasing cases of dengue have been reported in the month of September-October in the country. This year too, there are reports of an increase in the number of patients due to this mosquito-borne disease in the hospitals of the capital Delhi-NCR. According to the information received from the hospitals of Delhi, the number of patients has increased in the last one month, most of the people are recovering easily and returning. However, this time more cases of DEN-2, the most serious strain of dengue, are being seen in the capital, due to which dengue and its complications may increase.
Doctors say that everyone should keep making efforts to prevent dengue. Can someone who has had dengue once develop immunity against the next infection? Or is it dangerous for you to get dengue for the second time, let us understand this in further detail.
Dengue infection
Health experts say that you can get dengue infection many times in your life and the risk of this disease has been seen in people of all ages. Generally, in the context of infectious diseases, it is believed that if you have become a victim of infection once, then immunity develops in the body which can help in protecting you from the risks of infection next time.
However, health experts say, there is no evidence that after getting infected with one variant of dengue, the body develops immunity against other variants.
The next infection may be serious
WHO reports that there are four main strains of dengue, although all four serotypes are antigenically similar, cross-protection can be achieved only for a few months after infection by any one of them. Health experts say, if you get dengue infection for the second time due to any other serotype, it can be relatively more serious. Every subsequent infection with dengue can be a serious disease.
Risk of re-infection with dengue
Health experts say the risk of getting infected with dengue a second time is quite common, however, in case of a second infection, a change in the course of the disease or clinical presentation may be seen. In case of a second infection, the condition of the disease can become serious within the next five days after the mosquito bite.
Health experts say, that in severe cases of dengue, there is a risk of developing problems like dengue hemorrhagic shock, and internal bleeding, in which if timely treatment is not received, this condition can also be fatal.
Take measures to prevent dengue
Health experts say it is very important to keep taking measures to prevent the risks of infection a second time. Given the increasing danger of dengue, take preventive measures. It is important to make efforts to prevent mosquito bites by eliminating mosquito breeding sites such as waterlogging and spraying insecticides. Efforts should be made to increase the body's immunity, people who have weak immunity have a higher risk of developing serious diseases.
