Reports are circulating now about a guy who, while infected with a rare, drug resistant form of tuberculosis, traveled extensively from America to Europe and back through Canada – while he was aware of his disease and having being told not to travel. Great. You just have to think he’s either incredibly stupid or incredibly selfish, or both. Worryingly he traveled through Montreal and New York, but we won’t know if he had any impact as the incubation period can be up to decades.
