People of all ages, all nationalities and all incomes can get tuberculosis. It would be a mistake to think that developed countries are spared. After a century in decline, TB is making a worrying comeback in London and in New York. Each year over 25,000 people in the United States get tuberculosis. About 3,700 of these people live in New York City.
 

The number of people travelling in airplanes has risen dramatically over the past 40 years. TB travels with them. In many industrialized countries, at least half of TB cases are among foreign-born people.
 

The number of refugees and displaced people in the world is also growing. TB spreads like wild-fire in crowded refugee camps and shelter, and as many as 50 per cent of the world’s refugees could be infected with TB. As they move, they spread TB further.
