Epidemiology of Malaria
                                           drug-resistant malaria is a rapidly spreading global health threat
      Malaria is a public health problem today in more than 90 countries, inhabited by 2,400 million people – 40% of the
       world’s population
      An estimated 300 to 500 million cases each year cause 1.5 to 2.7 million deaths, more than 90% of which occur in
       children under age 5 in Africa. Malaria kills one child every 30 seconds
      Progresses made in the last 50 years in restricting the geographical areas affected by malaria are being eroded
       recently, due to changes in land use, global climate changes, armed conflicts/movement of refugees, easy
       international travel and development of multi-drug resistant strains of parasite.
      The vast majority of areas of endemic malaria show resistance to chloroquine (the oldest, cheapest treatment).
       Resistance to sulfadoxine-pyrimidine is emerging in most affected areas. Resistence to mefloquine has been
       observed in South-east Asia (areas of multi-drug resistance)




    No malaria
    Malaria present only in small, remote areas. No chloroquine-resistant
           P.falciparum.

    Intermediate malaria risk, no chloroquine-resistant strains of P.falciparum.                                                   Multidrug resistance areas
