Introduction:

Dengue is caused by the vectors Aedes aegypti and Aedes albopictus, producing mild to severe symptoms, including death. Mortality is associated with the circulating strain, the host's immunological characteristics, and the health system's preparedness. The importance lies in preventing transmission to avoid complications or mortality. The objective was to identify maternal-fetal complications of dengue during pregnancy in patients at a public hospital in Paraguay.

Materials and methods:

Descriptive, observational, cross-sectional, retrospective. Data were obtained from the medical records and laboratory results of patients who consulted in obstetrics. Criteria: Inclusion: Pregnant patients diagnosed with dengue; patients with complete medical records. Exclusion: Patients who stated they did not wish to participate.

Results:

40% of dengue diagnoses occurred in the 26- to 30-year-old age group, with the third trimester being the most affected at 47%, affecting the period between 36 and 40 weeks. 55% of patients consulted for fever and 21% for fever and headache. Maternal complications included threatened premature delivery in 12%, gestational hypertension in 9%, and low birth weight in 5% of fetal complications.

Discussion:

Problems associated with dengue in pregnant women include hypertension, risk of premature delivery, and hemorrhage. This arbovirus has been identified as a public health emergency. Elimination of mosquito breeding sites, keeping swimming pools clean, personal protection against mosquito bites, use of mosquito nets, and active community participation are recommended.
