How common is human T lymphotropic virus?
It is estimated that between 10 and 20 million people are infected by HTLV-I in the world. Only 0.25-2% of the infected individuals will develop a progressive neurologic disease named HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP).
Is HTLV-1 contagious?
The HTLV-1 virus is transmitted (passed) from an infected person to a non-infected person through bodily secretions and blood. It can be transmitted by sexual contact, via the blood through fresh blood transfusions or through re-use of contaminated needles or passed from mother to child through breast-feeding.
How long do you live with HTLV?
For smoldering and chronic ATLL, median survival is estimated to be ∼30 to 55 mo (9), whereas survival is estimated to be 10 mo for the lymphomatous and 8 mo for the acute subtype, respectively (9). Of HTLV-1–infected patients, 0.25 to 3.8% develop HAM/TSP.
What are the symptoms of HTLV 2?

- Sensory neuropathies (conditions that affect the nerves that provide feeling)
- Gait abnormalities.
- Bladder dysfunction.
- Mild cognitive impairment.
- Motor abnormalities (loss of or limited muscle control or movement, or limited mobility)
- Erectile dysfunction.
- Mycosis fungoides.
Who is at risk for HTLV?
The overall prevalence of HTLV-1 infection in a sample of MHD patients was similar to that of other viral infections, such as hepatitis B and C. Our data revealed that MHD patients who are older, unmarried or who have received blood transfusions are at higher risk for HTLV-1 infection.
