This man is likely to be infected in the UK but his symptoms only start when he is living in Houston, USA. ' This is evidence that the disease is still ongoing in the UK, ' said Lawrence B. Schonberger, an epidemiologist.

According to the government, the man has lived in Houston for four years and he returned to the UK earlier this year.

Schonberger says humans are infected with mad cow disease when they eat the brain or nervous system tissues of animals with mad cow disease. The previous case of infection in the United States was a woman from England and living in Florida. This person died last year and is also thought to have been infected since he was in England.

According to statistics, more than 170 people have died or have fatal symptoms of mad cow disease.
