What Causes Petechiae?

Cytomegalovirus

Despite the intimidating name, cytomegalovirus is a commonly occurring virus capable of infecting nearly anybody. This virus remains in an individual's body for their entire life after infecting them. The majority of individuals are unaware they have cytomegalovirus since it's rare for the condition to cause issues in healthy individuals. However, those who are immunocompromised or pregnant do have reason to be concerned about cytomegalovirus. Developing a cytomegalovirus infection during pregnancy can cause complications if the virus is passed on to the baby. If an individual's immune system is compromised, especially after an organ transplant, a cytomegalovirus infection might be fatal. The virus is spread through bodily fluids and has no cure. However, some medications can treat immunocompromised patients and newborns with the virus. Babies with cytomegalovirus might have petechiae, along with a host of more concerning symptoms, including an enlarged spleen and liver, impaired liver function, an abnormally small head, pneumonia, or seizures.
