CMV (Cytomegalovirus) is a common virus that belongs to the herpesvirus family. It can infect people of all ages and often remains dormant in the body after the initial infection. Most healthy individuals may not experience any symptoms, but the virus can cause serious health issues in those with weakened immune systems, such as HIV/AIDS patients or organ transplant recipients. CMV is primarily spread through bodily fluids, including saliva, urine, and blood. Pregnant women can pass the virus to their unborn babies, which may lead to congenital CMV infection, potentially causing developmental issues. Regular screening and preventive measures can help manage the risks associated with CMV.
