The main symptom of the disease is a high fever. The disease also destroys red blood cells and before the 20th century often resulted in death. The disease is caused by a parasite that is transferred to humans by a mosquito bite.

The disease can be removed from an area by draining the land. The cause of malaria was discovered in 1880 and this has enabled successful drugs to be developed against the disease. Find the book you want in seconds by author, title or subject.
