Difference in prevalence of hepatitis B markers in children born either in Sweden or in Turkey of Assyrian immigrants.
Sera from 95 children below 20 years of age born to Assyrian immigrants were tested for markers for hepatitis B virus (HBV). HBV markers were found in 26% of the study population. However, no markers were demonstrated in children born in Sweden. Of the 62 children born in Turkey or the Middle East 39% had HBV markers and 4 (6.5%) had HBsAg. Three of the 4 HBsAg+ children had anti-HBe and 1 HBeAg. These results suggest that the transmission of HB in Assyrians may be mainly horizontal rather than vertical. Children of Assyrian immigrants born in Sweden do not seem to constitute a risk group for transmission of HB, whereas those born in Turkey or the Middle East constitute the same risk as reported in a general population of Turks.
