For the prevention of dengue fever, a good approach is to avoid mosquito bites by sleeping mosquito net. Or screened windows and doors. Eliminate sources of stagnant water, where mosquitoes like to lay their eggs. Or feeding fish to eat the larvae of mosquitoes at. Today, the world has no vaccine to prevent dengue fever. So it is not surprising to know that. Population in the Western Pacific, South America, Southeast Asia, India, about five hundred thousand people a year fall ill with dengue fever. Statistical surveys of the World Health Organization shows. The number of patients with dengue each year for 50 years now. Has risen to 30 times the disease so severe as AIDS, tuberculosis and hepatitis for people in South America. And vicious enough For people with malaria in Southeast Asia, although doctors are vaccinated against many diseases, but developed a vaccine for dengue is proceeding slowly. There are four types of dengue viruses because each of them can make people sick. The patients will be treated and cured with medication first type of dengue virus type 2 virus, but when threatened they are eligible for another patient. The symptoms are more severe in the latter many times because the antibody that the body uses to fight off viruses type 2, can not kill the virus have died. The virus has a life, is going to hurt the immune cells that result in ill patients even further. And this is the reason Why are so many children who are sick with the disease die. This is because children who are breastfed body may have antibody for the virus. But when the child is receiving the type of virus. Dengue symptoms so severe When cause and effect, this is one way that doctors who were determined to create a dengue vaccine is a vaccine that can protect against all four dengue virus types simultaneously. Prevention of a certain type, but not the only one.
