Why is "Congenital varicella syndrome" trending?

Wikipedia Overview

Congenital varicella syndrome is a rare disease resulting from Varicella Zoster virus (VZV) infection during the period of gestation. Viremia during the primary infection can result in transplacental transmission of the infection to the developing fetus. An estimated 25% of fetuses get infected with varicella infection when the mother has a varicella infection during the pregnancy, but the risk of developing congenital varicella syndrome is around 2%; therefore, the majority of the outcomes are normal newborns. Patients with primary infection before 20 weeks of gestation are at a higher risk of developing the severe form of infection, affecting the eyes, limbs, skin, and the central nervous system. Diagnosis requires a documented history of primary infection in the mother and serial ultrasound demonstrating features suggestive of congenital varicella syndrome. There is no definitive treatment; termination of pregnancy in fetuses with severe features is recommended. Vaccination to prevent maternal varicella infection and proper counseling to avoid contact with infected people are important for the management options to reduce the incidence of congenital varicella syndrome.
