• Malaria is a life-threatening disease which is caused by mosquito bites. Malaria is caused by plasmodium parasite and is transmitted in humans through the bite of Anopheles mosquito. After an infected mosquito bites a human, the parasites begin to multiply in the person’s liver.
• It progresses to infect and destroy red blood cells in the body. Common symptoms of severe malaria include flu, fever and chills, deep breathing and respiratory distress, abnormal bleeding, signs of anaemia and impaired consciousness. Some cases of malaria can be controlled by early diagnosis. But there are some countries which are unable to treat malaria in the initial stages effectively.
