This study The aim of this article is to determine the health risk factors favoring the contraction of infections and the loss of pregnancies among pregnant women coming for consultations at public or private health centers in the Maman Mboualé district. The survey took place from June 03 to October 17, 2023. We used data from the reports of the various health centers surveyed and a questionnaire survey of 46 women living in Talangaï. Among the 46 cases of pregnant women studied, 39.1% were infected by bacterial infections, followed by viral infections (19.6%), parasitic infections (13.3%) and mycotic infections (6.5%). These results reveal the predominance of bacterial infections in pregnant women compared with non-pregnant women. Several factors favor these infections, exposing these women to more serious health risks that can lead to complications of their health condition or loss of pregnancy. These include factors linked to STIs and the practice of self-medication, then factors linked to the consumption of toxic substances and the exercise and practice of heavy work, then factors linked to the absence of food, body and sanitary hygiene and the insalubrity of concessions, and finally factors linked to stress and allergies among pregnant women living in Talangaï in general and in the Maman Mboualé district in particular.
