Create a PowerPoint for anemia in general with a brief overview of The

Create a PowerPoint for anemia in general with a brief overview of The four most common types of anemia in Zambia are microcytic hypochromic anemia (mainly iron deficiency), normocytic normochromic anemia, macrocytic anemia (often due to folate/B12 deficiency), and hemolytic anemia (frequently linked to malaria and sickle cell disease). Make it informative and about 20 slides
