Cytomegalovirus (CMV) 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 CMV 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 breast milk. Pregnant women can pass the virus to their unborn babies, which may lead to congenital CMV infection, potentially causing developmental delays or hearing loss in infants. Regular check-ups and good hygiene practices can help manage the risks associated with CMV.
