Background: The complications of the SARS-CoV-2 infection and its COVID-19 disease on mothers and their offspring are less known. Objective: The aim of this review was to determine the transmission, severity, complications of SARS-CoV-2 infection during the pregnancy. This review showed the influence of COVID-19 disease on the neonatal neurogenesis. Owing to no specific vaccines or medicines that were reported for the treatment of COVID-19 disease, this review suggested some control strategies like treatments (medicinal plants, antiviral therapy, cellular therapy, and immunotherapy), nutrition uptake, prevention, and recommendations. Discussion: This overview showed in severely states that SARS-CoV-2 infection during the early stage of pregnancy might increase the risk of stress, panic, and anxiety. This disorder can disturb the maternal immune system, and thus causing a neurodevelopmental disturbance. This hypothesis may be depending on the severity and intensity of the SARS-CoV-2 infection during pregnancy. However, vertical transmission of SARS-CoV-2 from dams to their fetuses is absent until now. Conclusion: During this global pandemic disease, maintaining safety during pregnancy, vaginal delivery, and breastfeeding may play a vital role in a healthy life for the offspring. Thus, international and national corporations should be continuing for perinatal management, particularly during the next pandemic or disaster time.

It is suggested that programming of the immune system starts before birth and is shaped by environmental influences acting during critical windows of susceptibility for human development. Prenatal and perinatal exposure to physiological, biological, physical, or chemical factors can trigger permanent, irreversible changes to the developing immune system, which may be reflected in cord blood of neonates. The aim of this narrative review is to summarize the evidence on the role of the prenatal and perinatal environment, including season of birth, mode of delivery, exposure to common allergens, a farming environment, pet ownership, and exposure to tobacco smoking and pollutants, in shaping the immune cell populations and cytokines at birth in humans. We also discuss how reported disruptions in the immune system at birth might contribute to the development of asthma and related allergic manifestations later in life.
