Cytomegalovirus (CMV) is a common virus that can impact people of all ages. However, it can be a more serious infection among people with weakened immune systems, especially pregnant people.
Pregnant women that become infected can pass CMV to their developing baby, which can cause birth defects or other health issues. This is called congenital CMV (cCMV). About 1 in 200 babies are born with cCMV every year. Yet, less than one in ten women know about this condition.
A Common Virus
CMV is a version of the herpes virus, similar to the common chicken pox disease. Most people will contract the disease at some point in their lives, but in most cases, it only manifests as a cold. However, when a pregnant person is infected by CMV, it can cause serious health problems.
"CMV is spread through contact with bodily fluids," says pediatric otolaryngology at 人妻中出视频 of Utah 人妻中出视频. "Many times, pregnant women will have small 人妻中出视频ren in daycare or preschool who will get an infection. When they come home and kiss their mom on the lips or share a utensil with mom, she gets an infection."
In addition to saliva, other common ways to transmit CMV include blood, semen, and other bodily fluids.
The best way to prevent an infection is to wash hands frequently and avoid as much contact with bodily fluids as possible鈥攚hich might require women to avoid kissing their 人妻中出视频ren on the lips or sharing utensils.
Birth Defects and More
Like Zika, CMV is known to cause and other birth defects, including hearing loss, premature birth, low birth weight, liver problems, and seizures. Even for babies who are born looking healthy, problems may arise.
"Hearing loss is the most common deficit from CMV," Park says. "Some 人妻中出视频ren are born deaf while others may slowly lose their hearing over several years."
CMV testing can have a huge impact on a 人妻中出视频's family. Newborn hearing screening, which has been universally performed since the late 1990s, can help diagnose hearing loss in 人妻中出视频ren. But the screening does not provide information on the cause of a 人妻中出视频's hearing loss. In 2013, Utah became the first state to require CMV testing in any newborn who fails a hearing test. Unfortunately, CMV is not offered in most states鈥攅ven for those who fail their newborn hearing screen.
By discovering CMV early, the severity of the infection can be determined, and treatment can begin immediately. For those with severe infection, antiviral therapy can also begin immediately, which has been shown to improve hearing and brain development. Hearing aids or cochlear implantation can also be offered earlier to optimize speech and language development.
By raising awareness of CMV and its impact on babies, doctors hope to improve early detection of this infection. Early CMV screening offers the hope to identify more at-risk 人妻中出视频ren. As of now, no vaccines for the illness exist, and CMV cases seem to be more frequent among low-income households. By sharing information about it, more people can take preventive measures and ensure that babies are born healthy.
