Respiratory syncytial virus bronchiolitis among refugees and
Bronchiolitis is a prominent illness in children with a high burden in the developing world. The objective was to assess bronchiolitis severity among infants and toddlers of refugees and asylum seekers who fled from developing countries with high disease burden to a developed country.

A retrospective cohort comparative-group study of children 0–24 months of age who were admitted with a diagnosis of respiratory syncytial virus (RSV) bronchiolitis was done. The refugees and asylum seekers (study group) were mostly from war-torn African countries, and the control group was comprised of children from Israel (controls), a developed country. The primary outcome was length of stay (LOS), and the secondary outcomes were nutritional support and disease characteristics.

--A total of 185 patients were included (92 refugees and 93 controls). The mean LOS was higher for the former compared to the latter (4.7±3.2 vs. 3.5±2 days, respectively).

--More hospitalized refugees required nutritional support compared to controls (48% vs. 24%, respectively).

--No differences were found in vital signs, physical findings and symptoms, laboratory results, or complications.

Finally, in comparison to the Israelis refugees and asylum seekers of underdeveloped countries had a longer course of RSV bronchiolitis and demanded greater nutritional support. This can indicate a more serious illness.
