💚 June is CMV Awareness Month 💚
Many people have never heard of Cytomegalovirus (CMV), even though it is one of the most common viruses people encounter in their lifetime. Most individuals are exposed at some point without realizing it because symptoms are usually mild or not noticeable. Once CMV enters the body, it stays for life.
During pregnancy, CMV becomes more concerning. It is the most common infection passed from a mother to her unborn baby in the United States, with about 1 in 200 babies born with Congenital CMV (cCMV). This infection can lead to a variety of health issues.
One of the most significant effects of cCMV involves hearing health. Congenital CMV is the leading non-genetic cause of childhood hearing loss, affecting the inner ear and auditory system. Some babies show hearing differences at birth, while others develop hearing loss later in childhood.
Around 1 in 10 babies born with cCMV show signs of infection at birth. Among those who appear healthy early on, another 10 percent may later develop issues related to the infection. The most common long term concern is hearing loss.
Many families only learn about cCMV after it impacts their child. Look out for our next post where we’ll share prevention tips and simple ways to reduce the risk.
