The woman has malaria and symptoms of anaemia. The malarial pathogens infect red blood cells where they multiply to form many new, genetically identical pathogen cells. These new pathogen cells burst out of the red blood cells. Describe how malarial pathogens can be transmitted from this woman to another person.
Name the type of nuclear division that results in new pathogen cells.
Suggest why infection with the malarial pathogen can cause anaemia.
