Introduction:

Neonatal infection is one of the most common diseases due to the sensitivity of these patients. This infection can lead to neonatal sepsis and increase mortality.

Objective:

Determine the clinical and epidemiological characteristics of late neonatal infection.

Methods:

Retrospective and cross-sectional descriptive study of records on neonates admitted to the neonatology service of "William Soler Ledea" Hospital in the period 2017-2019 with a diagnosis of infection. Records of infected infants undergoing surgery were excluded. The variables studied were: epidemiological, risk factors, clinical and paraclinical. Descriptive statistical techniques such as percentages, ratio, mean or average were used.

Results:

The sample consisted of 1078 patient´s records, with an infection rate of 59.4 × 100 admissions. Prenatal and conatal risk factors obtained prevalence ratio < 1. The postnatal risk factors with the highest prevalence were male sex (57.6%) and central venous catheterization (53.6%). From 83 to 88% of infected neonates had alterations in the hematopoietic profile. Respiratory, skin and soft tissue infections occurred in 36% of the neonates and gram-positive bacteria were the main isolated microorganisms. There were 11 patients who died representing a mortality rate of 22.9%.

Conclusions:

Morbidity due to late infection is remarkable, postnatal risk factors predominate and male sex; prematurity and low weight had the highest representation in the deceased ones.
