A study published in The EMBO Journal by Cleveland Clinic researchers highlights that even mild or asymptomatic SARS-CoV-2 infections in pregnant individuals can lead to serious inflammatory responses in fetuses. The study suggests that vertical transmission of the virus from mother to fetus may be more common than previously thought. Researchers found the virus and inflammatory markers in placenta and fetal tissues, indicating the impact on the fetus even without a full infection. The findings challenge the traditional definition of vertical transmission and emphasize the need for further research to understand the long-term effects on offspring and guide healthcare practice during public health crises.
