What disease is characterized by chills fever and anemia due hemoglobin being ingested the infective?

The disease characterized by chills, fever, and anemia due to hemoglobin being ingested by the infective is malaria. Malaria is a vector-borne infectious disease caused by protozoan parasites of the genus Plasmodium. The parasites are transmitted to humans through the bites of infected female Anopheles mosquitoes.

When an infected mosquito bites a human, the parasites enter the bloodstream and travel to the liver. In the liver, the parasites multiply and mature before infecting red blood cells. Once inside the red blood cells, the parasites continue to multiply, causing the infected cells to rupture and release more parasites into the bloodstream. This cycle of infection can lead to chills, fever, and anemia.

In severe cases, malaria can also cause jaundice, kidney failure, and even death. Malaria is a major public health problem in many tropical and subtropical regions of the world.
