Dengue fever is an infectious disease caused by the Dengue virus. The cause of dengue fever is the Aedes mosquito that transmits the virus from an infected person to a healthy person. People with dengue fever can experience severe pain in their muscles and joints.

Febrile convulsion syndrome is a common syndrome in breastfed children (under 2 years old), manifested by convulsions or tonic-clonic convulsions when the child has a high fever. This is a medical condition that requires emergency treatment because it can threaten the child's life or leave serious sequelae such as epilepsy, mental and motor retardation, especially in cases of prolonged febrile convulsions.
