Breitbart: "22 Percent of Resettled Refugees in Minnesota Test Positive for Tuberculosis" -- Updated

From the article:

One of every five refugees resettled in Minnesota by the federal government tested positive for latent tuberculosis [infection] in 2014, according to the state’s Department of Health. 

Only 4 percent of the general population in the United States tested positive for latent tuberculosis in the most recent report provided by the Centers for Disease Control.

Also:

26 percent of all foreign born cases of tuberculosis in Minnesota were from people born in Somalia. Somalians almost exclusively enter the state through the refugee resettlement program. 

Update (5/18/2016): "After 20 years of decline, tuberculosis inches up in U.S."--Star Tribune.

In the United States, Asians have the most cases and the highest rate of disease - 17.9 out of 100,000 persons. The top five countries of origin for foreign-born TB patients are Mexico, the Philippines, Vietnam, India and China. 

Immigrants and refugees are screened for TB and treated before entering the United States. Tourists, students and temporary workers are not screened. The CDC does not recommend across-the-board screening for everyone entering the United States, the CDC’s LoBue said. 

Because TB hits some ethnic and racial groups harder than others, TB patients can face discrimination and social isolation. Public health officials worry about finding ways to target high-risk populations with TB education and treatment without stigmatizing those groups.

 Because we wouldn't want to offend someone carrying a deadly disease.
