Malaria

Malaria is cause by a sponger that is transmitted from one human to another by the bite of impure Anopheles mosquitoes. In humans, the parasites transfer to the liver where they mature and release another form, the merozoites. These enter the bloodstream and pass on a disease to the red blood cells.

The fleas multiply inside the red blood cells, which then split within 48 to 72 hours, infecting more red blood cells. The first symptom usually occurs 10 days to 4 weeks after illness, though they can appear as early as 8 days or as long as a year later. Then the symptoms take place in cycles of 48 to 72 hours.

The bulk of symptoms are caused by the massive discharge of merozoites into the bloodstream, the anemia resultant from the demolition of the red blood cells, and the harms caused by large amount of free hemoglobin free into the circulation after red blood cells rupture.

Malaria can besides be transmitting congenitally and by blood transfusions. Malaria can be passed by mosquitoes in moderate climates, but the parasite disappears over the coldness.
