. In March 2020, the World Health Organization (WHO) announced the emergence of a global pandemic, COVID-19. A disease triggered by the new coronavirus infection (SARS-CoV-2). More recent findings indicate that the gestational period makes the mother and her offspring more susceptible to the new coronavirus and the rapid progression to the critical stage of the disease. The maternal organism presents a certain degree of immunological and cardiorespiratory deficiency due to physiological adaptations to the gestational period and, consequently, if affected by prenatal infections caused by viruses, they lead to an exacerbated Maternal Immune Activation (MIA), thus contributing to alterations in maternal-fetal neurogenesis, fetal myelinization, and is directly involved in the pathogenesis of neurodevelopmental disorders in the offspring, especially autism. Objective. This study hypothesizes that maternal COVID-19 infections during pregnancy are a potential risk for the offspring to develop Autism Spectrum Disorder. Conclusion. The exposure to viral infectious agents during the gestational period leads to exacerbated maternal immune activation. It contributes to alterations in maternal-fetal neurogenesis and is directly involved in the pathogenesis of neurodevelopmental disorders, being correlated to the predisposition to affective and psychiatric disorders in the offspring. Therefore, greater attention should be given to the offspring of pregnant women infected by COVID-19, since prenatal infectious processes have a strong correlation with the prevalence of Autistic Spectrum Disorder in the offspring.
