Introduction

Iran is the third country in the world with the highest number of registered refugees with the majority coming from Afghanistan. They suffer major health and social risks yet their health status has never been comprehensively determined.

Methods

This systematic review of the literature highlights major disparities among documented immigrants in health access, communicable and non-communicable diseases and the increasingly desperate plight of undocumented immigrants.

Results

Comparing with Iranian population, the findings suggest the higher prevalence of most diseases among Afghan immigrants and refugees. This highlights the importance of increasing the migrants’ access to health services from both public health as well as human rights perspectives.

Discussion

Although the Iranian government has taken new initiatives to overcome this challenge, certain issues have still remained unaddressed. Potential solutions to improve this process are discussed.
