Dengue virus (DENV) causes fever and haemorrhagic symptoms. DENV-2 is associated with more severe diseases.
Dengue infections are caused by four closely related viruses named DEN-1, DEN-2, DEN-3, and DEN-4. These four viruses are called serotypes because each has different interactions with the antibodies in the human blood serum. The four DENV serotypes mean that it is possible to be infected four times. Dengue season begins post-monsoon and stays till the onset of winter.
