 ==Epidemiology and Demographics==
 ===Prevalence===
-HTLV-1 infection in the United States appears to be rare. Although little serologic data exist, prevalence of infection is thought to be highest among blacks living in the Southeast. A prevalence rate of 30% has been found among black intravenous drug abusers in New Jersey, and a rate of 49% has been found in a similar group in New Orleans. It is possible that prevalence of infection is increasing in this risk group. Studies of HTLV-1 antibody indicate that the virus is endemic in southern Japan, in the Caribbean, and in Africa.
 ===Incidence===
-ATLL is relatively uncommon among those infected with HTLV-1. The overall incidence of ATLL is estimated at about 66 per 100,000 adult HTLV-1 carriers per year.
 ===Age===
 ===Gender===
 ===Race===
-Those cases that have been reported have occurred mostly among persons from the Caribbean or blacks from the Southeast (National Institutes of Health, unpublished data). There appears to be a long latent period between HTLV-1 infection and the start of ATLL.
