Some people who have malaria experience cycles of malaria "attacks." An attack usually starts with shivering and chills, followed by a high fever, followed by sweating and a return to normal temperature. Malaria signs and symptoms typically begin within a few weeks after being bitten by an infected mosquito.Human body is the reservoir of malaria; after a person gets malaria from the bite of an infected mosquito, the mosquito injects immature form of Plasmodium parasites into the host's body; travel through the person's bloodstream to the liver and grow into mature form; the mature form of parasites... Malaria is caused by the Plasmodium parasite. The parasite can be spread to humans through the bites of infected mosquitoes. There are many different types of plasmodium parasite, but only 5 types cause malaria in humans.
Malaria is an infectious disease caused by a parasite: it is spread by the bite of an infected mosquito. People catch malaria when the parasite enters the blood. The parasite causes a deadly infection which kills many people each year.

The parasite that causes malaria is a protozoan called 'Plasmodium'. Protozoa are organisms with only one cell, but they are not bacteria. Bacteria are smaller and simpler than protozoans.
People usually get malaria from the Anopheles or Culex mosquitoes: they are the vectors of the disease. The Plasmodium gets into people by the bites of mosquitoes. The Plasmodium is in the mosquito's special saliva.[1] The mosquito's saliva injects an anticoagulant into the person to prevent their blood from clotting. The person is then infected with Plasmodium as a by-product. This makes the person have the disease we call malaria.
Only the female mosquito gives people malaria, because only the female mosquito consumes blood. The male mosquito lives on the nectar of flowers. The female uses blood as a source of protein for its eggs.
Some people do not get malaria from mosquitoes. A baby can get it while inside its mother. This is called maternal-foetal transmission. People can also get malaria from a blood transfusion. This is when someone gives blood to another person. Another way people can catch malaria is by using a needle that someone with the disease used before them.
मलेरिया या दुर्वात एक वाहक-जनित संक्रामक रोग है जो प्रोटोज़ोआ परजीवी द्वारा फैलता है। यह मुख्य रूप से अमेरिका, एशिया और अफ्रीका महाद्वीपों के उष्ण तथा उपोष्ण कटिबंधी क्षेत्रों में फैला हुआ है। प्रत्येक वर्ष यह ५१.५ करोड़ लोगों को प्रभावित करता है तथा १० से ३० लाख लोगों की मृत्यु का कारण बनता है जिनमें से अधिकतर उप-सहारा अफ्रीका के युवा बच्चे होते हैं।[1] मलेरिया को आमतौर पर गरीबी से जोड़ कर देखा जाता है किंतु यह खुद अपने आप में गरीबी का कारण है तथा आर्थिक विकास का प्रमुख अवरोधक है।
