What is in a swamp?
Swamps are wetlands consisting of saturated soils or standing water and are dominated by water-tolerant woody vegetation such as shrubs, bushes, and trees.
Where are the swamps?
Where are Swamps Found? Swamp ecosystems are found on all continents of the world except for Antarctica. Some of the most famous are the Okavango Delta in Africa, the Sundarbans in India or the Everglades in the USA. In general, the most extensive areas of swamp in the USA are found in the Southeast.
Where is malaria found?
The highest transmission is found in Africa South of the Sahara and in parts of Oceania such as Papua New Guinea. In cooler regions, transmission will be less intense and more seasonal. There, P. vivax might be more prevalent because it is more tolerant of lower ambient temperatures.
What is malaria Class 9?
Malaria is a mosquito-borne infectious disease caused by various species of the parasitic protozoan microorganisms called Plasmodium.
How is swamp made?
Swamps start out as lakes, ponds or other shallow bodies of water. Over time, trees and shrubs begin to fill in the land. Plants die and decay and the level of the water gets lower and lower. Eventually, the original body of water becomes a swamp.
How did malaria spread?
Malaria spreads when a mosquito becomes infected with the disease after biting an infected person, and the infected mosquito then bites a noninfected person. The malaria parasites enter that person’s bloodstream and travel to the liver.
How is malaria spread?
Malaria is spread by the bite of an infected femaleAnophelesmosquito. Malaria may also be spread by transfusion of blood from infected people or by the use of contaminated (dirty) needles or syringes. People with untreated or inadequately treated malaria may spread infection to a mosquito that bites them.

Infection with P. falciparum may result in cerebral malaria, a form of severe malaria that involves encephalopathy. It is associated with retinal whitening, which may be a useful clinical sign in distinguishing malaria from other causes of fever.
What is the genus and species of malaria parasites?
Malaria parasites belong to the genus Plasmodium (phylum Apicomplexa). In humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi. Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%).
