Abstract
Dengue Hemorrhagic Fever is an infectious disease caused by dengue virus which is transmitted through bites of Aedes aegypti or Aedes albopictus[1]' In Indonesia particularly, there has not been much research on ABO blood type associated with dengue fever occurrence[2]. This study aims to see the ABO blood group description and its relation to the incidence of dengue hemorrhagic fever in Semarang. The DHF sample cases were obtained from three hospitals in Semarang city (n=39), from the period of March to May 2017 and the control groups were obtained from healthy respondents with matched age, sex, and the district location (n=39). The data was analyzed by Chi-Square test. The frequency distribution of blood groups in DHF patients was 6 type A (15.4%), 10 type B (25.6%), 7 type AB (17.9%) and 16 type O (41.0%). In control there were 10 type A (25.6%), 12 type B (30.8%), 9 type AB (23.1%) and 8 type O (20.5%). Comparison between blood group B, AB and O to blood group A resulted in the p-value of 0.875, 1.00, and 0.136 which not significant. Although DHF cases at three hospitals in Semarang are not related to blood type, the highest percentage of the patients had O blood group (41%).
