Fever During Pregnancy: Etiology and Fetomaternal Outcomes.

Purpose Etiological spectrum of fever in pregnant women and its impact on fetomaternal outcomes were studied. Methods This was a hospital-based prospective study, conducted over 12 months. All pregnant women with fever were screened and detailed etiological evaluation carried out. Maternal and foetal outcomes were noted. Results One hundred and eighty-one pregnant women with fever were included. Common causes were dengue 44 (24.3%), hepatitis E 26 (14.4%) and urinary tract infection (UTI) 22 (12.2%). Mosquito-borne diseases accounted for the highest burden 61 (33.7%). Second most common were diseases transmitted by feco-oral route 46 (25.4%). Maternal deaths occurred in 29 (16%) patients. Common causes of death were hepatitis E infection in 9 of 26 (34.6%) cases, dengue in 7 of 44 (15.9%) and tuberculosis in 5 of 11 (45.5%) cases. Conclusion Dengue, hepatitis E and UTI were the most common causes of fever during pregnancy. Most cases were caused by vector- and water-borne diseases and thus potentially preventable. Overall maternal mortality was 16%.
