A new study claims that explorer Christopher Columbus may have been responsible for bringing syphilis to Europe. The controversial theory has been debated for years, but the new study of molecular genetics may show whether the theory is true.

While other scientists dispute the claim, the team of US and Canadian experts feel their findings are backed by the fact that the first European outbreak occurred only two years after Columbus' return.
