Surveillance of Anaemia: Mapping and Grading the High Risk Territories and Populations.

Introduction: Surveillance of anaemia is an ongoing process for assessing iron status and anaemia prevalence among individuals and the communities they live in. Measuring blood haemoglobin levels is the commonest method espoused worldwide for screening individuals and populations for anaemia and iron deficiency. World Health Organization (WHO) proposed a classification of public health significance of anaemia in populations on the basis of prevalence estimated from blood levels of haemoglobin.
