As migrants suffer disproportionately from TB, accurate and timely detection of TB in migrants is critical to ending the global TB epidemic. See how we can protect migrants from TB.
TB Management


There are an estimated 1 billion immigrants living in the world today. That’s one in every eight people. Out of this massive number, around 281 million are international immigrants, meaning they moved from one country to another, and approximately 82.4 million are forcibly displaced individuals who were forced to leave their homes due to various reasons (1).

Unfortunately, immigrants often struggle to access proper healthcare, which puts them at a higher risk of getting infected or developing tuberculosis (TB). This lack of access to medical services can be due to various reasons, such as language barriers, limited financial resources or unfamiliarity with the healthcare system in their new country. To make matters worse, many immigrants live and work in poor conditions, which can further increase their susceptibility to TB.

So, while immigrants contribute greatly to the diverse fabric of our world, it's important to address the challenges they face in terms of healthcare and living conditions.

People are on the move, and so is TB
As immigrants suffer disproportionately from TB, accurate and timely detection of TB in immigrants is critical to ending the global TB epidemic. The WHO recommends systematic TB testing and treatment for immigrants originating from countries with a high burden of TB (2).

Helping immigrants start a new life without TB

How can a doctor reach out to foreign patients who don't speak the language, have distrust of doctors and have priorities that supersede a latent disease they may not even be aware of? Dr. Christian Herzmann, an expert in respiratory disease, is exploring uniquely creative ways to connect with patients – two-thirds of whom are immigrants or refugees in Germany.

Understanding the USCIS TB testing guidelines for immigrations exams

The USCIS no longer accepts the tuberculin skin test (TST) for US immigration exams. Instead, a TB blood test (interferon-gamma release assay or IGRA) is required for permanent resident applicants. View the on-demand webinar where Dr. Alawode Oladele introduces the new IGRA requirement and the updated technical instructions.
