Countries with high prevalence HTLV infection
An area of ‘high prevalence’ is defined as a prevalence over 1% in the general population or prevalence of over 1/10 000 among first-time blood donors.1 These countries are listed below. In many parts of the world, there is inaccurate data on prevalence, so this list is likely to be incomplete.
