One of my friends had just gone for the medical in London with his family members but found out that he was Syphilis positive........his blood test revealed that. He including all the family members were normal in other tests such as HIV negative, Chest X-ray and so on- only this had made him in a difficult situation. He told me that he had once got this 12-13 years ago due to unprotected sex and was then treated. His doctor told him that it stayed on latent (dormant) stage eventhough he was treated 12-13 years ago. Then the doctor gave him 3 anti-biotic (penicillin) for 3 consecutive weeks and he wrote on the medical form that the Syphilis had been treated according to the Canadian STD Guidelines (1998) and informed him that the case would not deny him the visa. But now he is very worried, depressed and embarrassed. Can anyone tell that will this really cause the problem for Immigration visa?
