Profiling infectious diseases in Turkey after the influx of 3.5 million Syrian refugees

Abstract

Background: since 2011, the conflict in Syria has led to over five million refugees. Turkey hosts the highest number of Syrian refugees in the world. By February 2019 over 3.6 million people had fled to Turkey to seek safety. Only 6.1% of Syrian refugees live in temporary shelters. Owing to the disrupted healthcare services, many children coming from the conflict zones are less likely to have received vaccination. In temporary shelters immunization coverage is >95% and the refugee population is receptive to vaccination. Aims: the objective of this study was to review the infectious diseases situation among Syrian refugees in Turkey. Sources: we have reviewed the reports and studies provided by the governmental and non-governmental organizations and obtained more detailed data from the Ministry of Health in Turkey. Content: between 2012 and 2016, 1 299 209 cases of respiratory tract infection and 158 058 episodes of diarrhoea with 59 bloody diarrhoeas were reported; 1354 hepatitis A cases and 108 active tuberculosis cases were detected and treated in the temporary shelters for Syrian refugees. Overall in Turkey, 7794 cutaneous leishmaniasis have been reported. Implications: since the influx of Syrian refugees, there has been an increase in cases of leishmaniasis and measles. No significant increase was detected for tuberculosis, other vector-borne infections, and healthcare associated or sexually transmitted infections. The Syrian refugees can be considered as a vulnerable group in Turkey due to their living and working conditions. Based on available data and our detailed analysis, the numbers show a stable situation regarding infectious diseases.
