I will choose : Malaria.
Malaria is an infectious disease caused by a parasite of the genus Plasmodium (the most predominant is the falciparum species), spread by the bite of certain species of anopheles mosquitoes. The malaria parasite is mainly transmitted, at night, during the bite by a female mosquito of the genus Anopheles, itself contaminated after stinging an individual with malaria. The parasite infects the victim's liver cells and then circulates in the blood, colonizing the red blood cells and destroying them.
The symptoms are: generalized fatigue, loss of appetite, dizziness, headache, digestive disorders (gastric embarrassment), nausea, vomiting, abdominal pain, diarrhea and diffuse myalgia.
