Neonatal herpes

life science Maturity 11-13 Next article →

Neonatal herpes is a serious infection in newborn babies. It is caused by the herpes simplex virus, also known as HSV. This virus can affect babies in different ways. Some babies only get small blisters on their skin. Others might have a much harder time. The infection can spread to the liver or the brain. This is why doctors watch newborn babies very closely.

There are three main ways the virus works. The first is called SEM, which means skin, eye, and mouth herpes. This causes bumps on the outside of the body. The second way is called DIS, or disseminated herpes. This type affects the organs inside the body, like the liver. The third way is called CNS herpes. This affects the central nervous system, which includes the brain. Babies with CNS herpes may have seizures or tremors.

Most babies get the virus during childbirth. This happens when they touch infected fluids in the birth canal. About 85% of cases happen this way. Some babies get it before they are born. This is called an in utero infection. About 5% of babies get the virus this way. A small amount, about 10%, get it after they are born. This can happen from other sources outside the mother.

Scientists and doctors have learned a lot over time. In the United States, the death rate is going down. It is now about 25%. A few decades ago, the death rate was as high as 85% for untreated cases. Doctors now use antiviral medicines like acyclovir. These drugs help fight the virus. This is why more babies are surviving today.

In the United States, about 1 in every 3,500 babies get this infection. Globally, it affects about 1 in 10,000 births. Doctors use blood tests to find the virus. They also use swabs on the mouth or nose. Sometimes they use an MRI to look at the brain. These tests help doctors start medicine quickly. Early treatment is the best way to help a baby stay healthy.
