Throughout the history of immigration, people have raised concerns about waves of new immigrants bringing disease with them into the country. It's true that new populations have sometimes introduced illness into the population, but this argument has also been frequently used as a weapon to stir opposition to immigration.
VermontWatchdog.org, a website that describes itself as a government transparency news site, recently ran an article with the headline "More than one-third of refugees in Vermont test positive for tuberculosis." It claims that the Vermont Health Department is deliberately covering up this fact. The piece has since been picked up by conservative websites around the country.
Patsy Kelso, Vermont Health Department epidemiologist, joined Vermont Edition to explain what tuberculosis is and the number of incidences in the state population.
