Pediatric cytomegalovirus infections can be categorized as either acquired or congenital infections, where congenital infections may present with twitching symptoms and acquired infections do not usually present with this condition. Cytomegalovirus is a type of herpesvirus, and children with acquired infections often have respiratory tract infections and generally do not have twitching symptoms. In congenital infection, cytomegalovirus will be latent in the body, mainly reflected in the central nervous system, urinary system, liver and other abnormal lesions, and will show twitching, convulsions, spasms and other symptoms. When a child has a twitching condition, he needs to go to the hospital as soon as possible for a detailed examination to clarify the cause of the twitching and treat the symptoms under the guidance of the doctor.
