Tropical spastic paraparesis

Tropical spastic paraparesis, abbreviated TSP, is a medical condition that causes weakness, muscle spasms and sensory disturbance, resulting in paraparesis, which is weakness of the legs. The Wikipedia lead attributes it to the human T-lymphotropic virus. As its name suggests, it is most common in tropical regions, including the Caribbean. The lead also records one preventive measure: blood transfusion products are screened for antibodies to human T-lymphotropic virus 1, known as HTLV-1. The entry therefore sits among conditions tied to a viral cause and a geographic pattern. It records what the source states and is not medical advice.
