Abstract
Introduction: Breast milk (BM) is an ideal food for infants. In addition to the protective factors, the infant can be infected during breastfeeding, the LM itself being the source of contagion. Viruses are present in colostrum, but in some cases, there is no proven vertical transmission as in the case of respiratory viruses. Little is known about the excretion of the SARS-CoV-2 Virus that infects the maternal organism.
Objective: to investigate the presence of virus in human colostrum samples from postpartum women in the immediate postpartum period.
Methods: Cross-sectional, observational and descriptive study conducted on a convenience sample of mothers over 18 years of age, 50 healthy and 3 with a diagnosis confirmed by RT-PCR of nasal Swab for COVID-19, in the immediate postpartum period at Maternity Hospital of Santa Casa de São Carlos (State of São Paulo, Brazil), who consented to their participation in writing in the period from 01/08/2020 to 30/11/2020. Verification was performed through nucleic acid extraction and qualitative virus detection by RT-PCR. Descriptive statistics (frequency and percentage) were used to present the results.
Results: Samples (one ml) of colostrum from 53 postpartum women were obtained. The presence of respiratory virus genomes was observed in 2 samples (3.8%).
Conclusion: SARS-CoV-2 virus genomes were observed in 2 of the colostrum samples; however, isolation of the respective viruses was not possible.
