World Map of Epidemiology of Hb Disorders
~ 7% of the global population carries an abnormal Hemoglobin (Hb) gene
~ 3% of all hemoglobinopathy-related deaths occur in children under 5 years of age
DO YOU KNOW THAT…
300,000 -500,000 children are born with Hb disorders annually:
• ~80% of affected children are born in developing countries
• ~70% are born with sickle cell while the rest with thalassaemia
disorders
• ~50-80% of children with sickle cell anaemia, and
• 50,000 – 100,000 children with thalassaemia major die each year in low and middle income countries

Global Program Objectives?
Concentrate on management and therapeutic approaches unlikely to ever reach most or on those with possible wide application
Create a few excellent centers with access limited to few patients or maximize access and availability of services?

Sickle Cell Disease Global
WHO SCD 2006 Report: Recommendations
• Model of a national control programme developed in high-resource countries is not appropriate for most low-resource settings.
• Sickle-cell disorders should be covered by health-service planning in all countries where they are common.
Sickle Cell Disease Global
WHO SCD 2006 Report: Recommendations
• All components of prevention and treatment should be considered together.
• Systematic gathering of information on most cost-effective approaches for prevention and treatment should be promoted.
• Essential areas of work should cover prevention and counselling, early detection and treatment, surveillance and research, and community education and partnership.
Sickle Cell Disease Global
WHO SCD 2006 Report: Recommendations
Sickle Cell Disease Global
• In areas where sickle-cell anaemia is common, dedicated centers are required in order to ensure adequate services for prevention and treatment.
• Ideally, the disease should be identified at birth as part of a screening programme or neonatal diagnosis and affected individuals urged to attend a center periodically for evaluation.
• A close working relationship between the primary-care provider and the center is essential for appropriate care.

WHO SCD 2006 Resolution 59.20
Sickle Cell Disease Global
WHO 59th WHA: SCD 2006 Resolution: PreambleHaving examined the report on sickle-cell anaemia;1. Recalling resolution WHA57.13 on genomics and world health, and the
discussion of the Executive Board at its 116th session on control of genetic diseases, which recognized the role of genetic services in improving health globally and in reducing the global health divide;
2. Recalling decision Assembly/AU/Dec.81 (V) of the Assembly of the African Union at its Fifth Ordinary Session;
3. Noting the conclusions of the 4th International African American Symposium on sickle-cell anaemia (Accra, 26-28 July 2000), and
4. the results of the first and second international congresses of the International Organization to Combat Sickle-Cell Anaemia (respectively, Paris, 25-26 January, 2002 and Cotonou, 20-23 January 2004); …….
Sickle Cell Disease Global
WHO 59th WHA: SCD 2006 Resolution 59.20 :
1. URGES Member States having sickle-cell anaemia as a public health problem:
(1) to develop, implement and reinforce in a systematic, equitable and effective manner, comprehensive national, integrated programmes for the prevention and management of sickle-cell anaemia, including surveillance, dissemination of information, awareness-raising, counselling and screening, such programmes being tailored to specific socioeconomic, health systems and cultural contexts and aimed at reducing the incidence, morbidity and mortality associated with this genetic disease;
Sickle Cell Disease Global
WHO 59th WHA: SCD 2006 Resolution 59.20 :
REQUESTS the Director-General:
(1) to increase awareness of the international community of the global burden of sickle-cell anaemia, and to promote equitable access to health services for prevention and management of the disease;
(2) to provide technical support and advice to national programmes of Member States through the framing of policies and strategies for prevention and management of sickle-cell anaemia;
Sickle Cell Disease Global
WHO 59th WHA: SCD 2006 Resolution 59.20 :
(3) to promote and support:
(a) intercountry collaboration to develop training and expertise of personnel and to
support the further transfer of advanced technologies and expertise to
developing countries;
(b) the construction and equipment of referral centres for care, training and research;
Sickle Cell Disease Global
WHO 59th WHA: SCD 2006 Resolution 59.20:
(4) to continue WHO’s normative functions in drafting guidelines, including good practices and practical models, on prevention and management of sickle-cell anaemia with a view to elaborating regional plans and fostering the establishment of regional groups of experts;
(5) to promote, support and coordinate the research needed on sickle-cell disorders in order to improve the duration and quality of life of those affected by such disorders.

WHO Experts Meeting, 2007
The meeting was convened at the request of the WHO’s Human Genetics Programme (HGN) following the WHO Resolutions on May 2006 on Sickle Cell Disease (WHA59.20) and Thalassaemia (EB118.R1), respectively.

WHO Experts Meeting: Report
The overall consensus of the group was to promote the WHO Resolutions on
Sickle Cell Disease and Thalassaemia
Sickle Cell Disease Global
WHO Experts Meeting: Recommendations (1/3)• Efforts should be intensified on expanding the database
on the epidemiology and available control services.
• Implementation and strengthening of programmes, including:
i. Community Awareness;
ii. Training of Health Professionals;
iii. Pilot studies;
iv. Research;
v. Cost-effectiveness in programme design, and;
vi. Strengthening of medical and genetic services in low-

• Funds should be secured for the development and
initiation of services for care, and successful
implementation of control programmes
• Efforts should focus on the identification and the
promotion of affordable interventions.

during which activities for raising public awareness
• Involving other potential stakeholders, such as
patients/parents organizations and other national and
international health related agencies

Report of Sickle Cell Disease Group
Patient Ascertainment and Early Diagnosis
• Importance of early diagnosis of sickle cell disease.
• Best achieved by newborn screening, associated with• comprehensive care including close follow-up• appropriate immunization • parental education, and, • documentation of disease problems.
• Children missing newborn diagnosis should be diagnosed as part of a minimal care package for Primary Care Centres.
