• Recognizing the burden

    Recognizing the burden of disease will aid policy-makers define priorities and secure resources for diagnostic purchases.

  • Estimating the impact

    Estimating the impact of a disease on a specific population is key for planning diagnostic strategies that target the most at risk.

  • Prevention and control

    Assessing different diagnostic alternatives is key to choosing the best strategy to meet population needs, the WHO Essential Diagnostic list (EDL) is a great place to start.


What is burden of disease?

Burden of disease refers to the health outcomes that a specific disease has on a population, usually measured by disability or morbidity (quality of life) and mortality (deaths).

What is the difference between incidence and prevalence of a disease?

The incidence of disease represents the rate of occurrence of new cases arising in a given period in a specified population, while prevalence is the frequency of existing cases in a defined population at a given point in time.

What is the WHO EDL?

The essential diagnostics list (EDL) is an evidence-based guide, developed by the WHO, that looks at disease prevalence globally and for each condition recommends the appropriate diagnostic test. That guidance aims not only to improve the health system’s capacity to reach accurate diagnoses, it also saves precious health resources that would otherwise be wasted on inappropriate treatment or lengthy hospital stays.
