disease is not found all over the world. For some reasons
it is not fully understood the disease is mainly prevalent
in countries around Mediterranean like Greece,Italy, Cyprus,
Turkey, Egypt, Morocco, Tunisia, etc and then a narrow
south eastern band comprising countries like Palestine,
Iran, Saudi Arabia, Afghanistan, Pakistan, part of India,Maldives,
Bangladesh, Myanmar, Thailand, Malaysia, Part of Indonesia
etc. Even though around Mediterranean the disease is homozygote
Beta Thalassaemia, as one travels southeast haemoglobin
E trait becomes more and more prevalent and the disease
becomes somewhat of intermediate nature called HbE/Beta

Thalassaemia in Bangladesh
According to who publication No.8-5 about 7-8% of the population of Bangladesh are carriers of Thalassaemia and the blood related genetic disorder like HbE disease. Bangladesh Thalassaemia society also felt the necessary to carryout a survey to ascertain how many people are carriers of Thalassaemia and HbE disease. Accordingly BTS organized survey among 1022 marriageable college and University Students of both sexes with the help and assistance of Canadian International Development Agency.
