Malaria - GCSE Biology Definition

Malaria is a serious disease caused by Plasmodium parasites that are spread to humans through the bites of infected female mosquitoes, mainly in tropical and subtropical regions. These parasites enter the body and travel to the liver, where they grow and multiply. Once they leave the liver, they enter the bloodstream and infect red blood cells, causing symptoms like fever, chills, and fatigue. If not treated, malaria can lead to life-threatening health issues, so it's important to take preventive measures in areas where it's common. Understanding malaria helps students learn about how diseases are transmitted and how they can be prevented.
