Klok S, van Dulm E, Boyd A, et al. - Undocumented migrants and uninsured legal residents in the Netherlands were screened for HBV, HCV and/or HIV infections to determine their prevalence.

• A total of 1,376 residents were invited for participation in this cross-sectional study; 784 (57%) of these finally participated.

• 451/784 (58%) participants underwent laboratory testing.

• HBV exposure was recorded in 29.7% with 2.5% having chronic HBV infection, 64% of which were newly diagnosed.

• HCV exposure was recorded in 2.3% with 0.7% having chronic HCV infection, all of which were newly diagnosed.

• HIV-positive status was recorded in 1.1%, 40% of which were newly diagnosed.

• The study population had overall a higher prevalence of chronic HBV, chronic HCV and HIV infections relative to the Dutch population, highlighting the relevance of case finding for these infections through primary care and public health in this specific group of migrants.
