Malaria is usually contagious, with the greatest possibility of transmission being the bite of a mosquito infected with Plasmodium, which is the main route of infection with Plasmodium. Then there is blood transmission, which can be contracted by importing blood with Plasmodium or sharing syringes with patients who have Plasmodium. There is also vertical transmission from mother to child, where a pregnant woman with the parasite or malaria can enter the fetus through the placenta and cause congenital malaria in the newborn. Malaria is an insect-borne disease caused by infection with Plasmodium, which is mainly transmitted through the bite of infected mosquitoes. The main symptoms of malaria are chills, fever and sweating. The chills start with chills at the end of the extremities, followed by chills all over the back, blue nails and pale face, as well as generalized muscle and joint pains and shivering.
