Infection of the mother with SARS-CoV-2 during pregnancy can lead to disorders in the development of the baby’s nervous system, which increase the likelihood of mental illness. This conclusion was made by scientists at the University of Washington from Seattle (USA).
“There is good cause for concern, as activation of the maternal immune system has different effects on the development of the fetal nervous system and increases the long-term risks of neuropsychiatric disorders, as shown in mouse and human cell models,” the authors wrote in an article in the journal Nature Immunology.
COVID-19 poses a danger to the fetus even if the virus is not transmitted directly to it, scientists say.
The analysis of umbilical cord blood of newborns not infected with coronavirus, whose pregnant mothers underwent COVID-19, showed that the infection of the mother’s body causes noticeable changes in the child’s immunity. It changes the concentration of various cells of the immune system (natural killer cells, T cells, cytokines, monocytes and others), and also forms the so-called polyfunctional cytokine response, which prepares the body for the rapid production of many cytokines. At the same time, the response in the fetus continues to operate even long after the mother’s illness. Its maximum confirmed duration was 221 days from the date of diagnosis.
