Hidden Threats: Why Detained Migrants Face a Health Crisis You've Never Heard Of

"Unveiling the alarming rates of parasitic and viral coinfections among detained migrants from Sub-Saharan Africa and Latin America, and why it demands immediate action."


Imagine being uprooted from your home, facing uncertainty in a new land, and then finding yourself behind bars. Now, add a hidden layer to this already difficult situation: the increased risk of parasitic and viral infections. For many detained migrants, this is a harsh reality, one that often goes unnoticed and untreated.

A recent study sheds light on this critical issue, revealing alarmingly high rates of coinfections – the presence of multiple infections at once – among detained migrants from Sub-Saharan Africa (SSA) and Latin America (LA). These aren't just any infections; they're often persistent parasitic neglected tropical diseases (NTDs) like schistosomiasis and strongyloidiasis, combined with viral infections such as HIV, hepatitis B (HBV), and hepatitis C (HCV).

Why is this happening? Migrants from these regions may carry these infections with them, and the conditions in detention centers can exacerbate the problem. Limited access to healthcare, poor sanitation, and lack of awareness all contribute to a perfect storm where these diseases thrive. This isn't just a health issue; it's a human rights crisis that demands our attention.

What Infections Are Lurking Undetected?

The study, conducted in a Swiss pretrial prison, paints a concerning picture. Researchers screened 201 participants, primarily from SSA (85.6%) and LA (14.4%), and uncovered significant prevalence rates of several infections:

The team found multiple infections in a single person are more common than we expected. For instance, nearly 5% of people from Sub-Saharan Africa who were tested had both schistosomiasis and chronic HBV. There are other combinations that also showed up like Schistosomiasis with HIV, HIV with chronic HBV, HIV with HCV, and Schistosomiasis with Strongyloidiasis.

  • HIV: 3.5% (4.1% in SSA, 0% in LA)
  • Chronic HBV: 12.4% (14.5% in SSA, 0% in LA)
  • Viraemic HCV: 2.0% (1.7% in SSA, 3.4% in LA)
  • Strongyloidiasis: 8.0% (8.1% in SSA, 6.9% in LA)
  • Schistosomiasis: 20.3% in SSA (not endemic in Latin America)
These numbers are far from just statistics. They represent real people, many of whom are unaware of their conditions and the potential health risks they face. What's even more alarming is that a significant percentage of those infected were unaware of their status: 42.9% of HIV-positive individuals, 52% with chronic HBV, and a staggering 75% with HCV were undiagnosed. This lack of awareness underscores the urgent need for increased screening and awareness programs within detention settings.

A Call to Action: What Can Be Done?

The study's findings highlight a critical gap in our approach to migrant health and detention center management. It's time to move beyond simply acknowledging the problem and implement concrete strategies to address it. This includes routine screening for parasitic and viral infections, access to appropriate medical care and treatment, and educational programs to raise awareness among detainees and staff. By prioritizing the health and well-being of this vulnerable population, we can uphold human rights, prevent the spread of infectious diseases, and create a more just and equitable society for all.
