Dengue is an acute febrile disease caused by a virus , one of the major public health problems in the world . Its main transmission vector is the mosquito Aedes aegypti , which develops in tropical and subtropical areas .
The World Health Organization ( WHO) estimates that 50 to 100 million people become infected annually with dengue in more than 100 countries on all continents except Europe . Approximately 550,000 patients require hospitalization and 20,000 die from dengue.
There are four types of dengue , because the causative dengue virus has four serotypes : DEN - 1 , DEN - 2 , DEN - 3 and DEN - 4 . Infection by one of them gives permanent protection to the same serotype , but partial and temporary immunity against the other three .
Although it seems somewhat aggressive , the disease can progress to dengue hemorrhagic fever and dengue shock syndrome , characterized by bleeding and falling blood pressure , which increases the risk of death . The best way to combat this evil is acting preventively , preventing mosquito breeding .
Dengue virus has four variations : DEN - 1 , DEN - 2 , DEN - 3 and DEN - 4 . All types of dengue cause the same symptoms.
When a person is infected with a certain type of virus , it creates antibodies in your body and will not contract the disease by the same virus , but can still be infected by the other three types . This means that you can only get dengue four times .
