Here is a summary of the passage:
Malaria is a serious mosquito-borne infectious disease that affects both humans and various animals. This illness is specifically transmitted by the female Anopheles mosquito, which thrives in hot and wet environments globally. The Anopheles mosquito possesses a long, straw-like proboscis, which it uses to draw blood. Notably, only the female mosquito feeds on blood, as the males subsist on plant-based liquids. The actual cause of malaria is a microscopic parasite, a protozoan, introduced into the body during a bite. When an infected female Anopheles mosquito bites a person, it injects these protozoan parasites directly into the bloodstream. These parasites then travel to the liver, where they multiply rapidly. After this multiplication phase, they re-enter the bloodstream and begin to infect red blood cells. The parasites consume these red blood cells, which are crucial for transporting oxygen throughout the body. This destruction of red blood cells leads to a significant lack of oxygen, causing the infected individual to feel extremely unwell. Common symptoms of malaria include severe headaches, vomiting, and potentially dangerous convulsions. Malaria is a devastating global health problem, responsible for more deaths than any other disease worldwide. Each year, an estimated 300 to 500 million people contract malaria, with over one million fatalities.
