Pregnancy Outcomes According to the Gestational Age of Acquiring COVID-19
Pregnancy Outcomes According to the Gestational Age of Acquiring COVID-19
A new coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV2)
 appeared in Wuhan, China and it arrived to Europe 2-3 months later. It infected millions of
 persons and led to the death of thousands until May 2020 where numbers of infections per week
 decreased significantly. However, starting September, number of infections started to
 escalate again and continued to rise until now.

 Hundreds of good quality articles were published during this period to study the relationship
 and effects of this virus on pregnancy and vice versa, as well as to determine the adverse
 neonatal and obstetrical outcomes following the infection. In a case-control study using
 propensity score matching at the level of age, body mass index and comorbidities (diabetes,
 hypertension, asthma), pregnant women over 20 week's gestation had significantly higher risk
 for intensive care unit stay, endotracheal intubation, hospitalization for disease related
 symptoms and need for oxygen therapy. A new systematic review also demonstrated increased
 risk for ICU admission in pregnant women compared to non-pregnant women and to non-infected
 pregnant women.

 On the other hand, many researchers have demonstrated that the rates of preterm delivery and
 cesarean delivery have increased as well, others reported a close relation between SARS-CoV2
 infection and preeclampsia or preeclampsia like condition. Enormous effort was done in order
 to understand adverse outcomes related to this infection, however, most studies included
 patients in the third or late second trimester. Few studies stratified adverse outcomes of
 the patients according to the trimester of infection.
