A Russian doctor has announced that individuals born in the spring season may be more prone to autoimmune diseases, such as multiple sclerosis. According to Russian media, Dr. Alexander Myasnikov suggests that, based on a theory grounded in statistical data, the month of birth influences the susceptibility to develop multiple sclerosis. The Russian doctor states, "The lowest number of multiple sclerosis patients is born in September and October, while those most at risk are born in April and May. But why? It is believed that the pregnant woman contracted a viral infection, which is transmitted to the child, and after 15 years post-birth, this infection becomes active." According to the Russian doctor, a deficiency of vitamin D and a lack of sunlight during pregnancy can negatively affect the health of the mother, especially since follow-up results have confirmed a link between viruses and the development of autoimmune diseases. He adds, "Infection by a specific type of virus causes immune transitions that lead to inflammation," noting that the true cause of the disease remains unknown and has not been fully studied.
