Preterm Birth Associated with COVID-19

Abstract

Introduction: The COVID-19 responsible for the pandemic has not only produced alterations at the pulmonary level but has also affected other types of population such as pregnant women and has brought with it different complications such as premature birth.
Objective: To identify the relationship between premature birth and COVID-19.
Methods: A narrative review was carried out including all the studies performed between March 2020 and May 2021, which evaluated women during their last trimester of pregnancy, and who were carriers of COVID-19 infection. Information was reviewed in Clinical Key, Cochrane Library, Pubmed, SciELO, and Medline databases.
Conclusions: The symptomatology that prevailed in pregnant women with mild SARS-Cov-2 infection was fever and dry cough, while in moderate to severe infection they had hypoxia, dyspnea and tachypnea. There is high prevalence of premature labor when
contracting SARS-Cov-2, and it was even found that this prevalence was double compared to uninfected pregnant women. This prevalence was observed in pregnant
women who had moderate to severe symptoms of COVID-19 due to the pro-inflammatory
state during the third trimester of pregnancy.
