Malaria

• Malaria is a communicable disease. It is spread by a pathogen.
• The malaria pathogen is an example of a protist.
• People with malaria experience repeated bouts of fever. Malaria can be fatal.
• First, the infected person is bitted by a mosquito. The malaria pathogen passes into the mosquito.
• The mosquito bites a different person and passes the malaria pathogen to them.
• Scientists call the mosquito a vector because it carries the pathogen from one person to another person.
• We need to stop the vector (the mosquito) from breeding.

  Mosquitos breed in still water. To stop mosquitos from breeding, we need to find areas of sill water and drain them.
• Stopping the spread of malaria:

  We can spray areas of still water with insecticide which kills mosquitos.
• As it is almost impossible to kill all mosquitos, another thing we could do to reduce the spread of malaria is to prevent the mosquitos from biting humans. One of the best ways to do this is to sleep under a mosquito net.
