Answer:
malaria
Step-by-step explanation:
"Malaria" is a mosquito-borne illness that is caused by a parasitic protist called "Plasmodium protozoa." These parasites are carried by mosquitoes. Once a mosquito bites a human, it creates an opening for the parasites to enter. The parasites then become harmful once they enter the human body. They infect the human's Red Blood Cells (RBCs), which causes several symptoms such as fever, fatigue, headache, cough, nausea, etc.
