"TB Man's" father- in-law is U.S. government's top TB reseacher!

The case of the US man who flew across the Atlantic and Europe while infected with a dangerous form of tuberculosis took a bizarre twist today when it emerged his father-in-law is a specialist on the infection.

It was also revealed that the man's father-in-law is Dr Robert Cooksey, a microbiologist at the US Centre for Disease Control in Atlanta, who works in the division of tuberculosis elimination and conducts laboratory research into the disease. But in a statement issued by the CDC, Dr Cooksey denies there is any link between his work and his son-in-law's infection.
