B25: Cytomegaloviral disease

B25.0: Cytomegaloviral pneumonitis

There are many different types of viruses. You have been infected with the cytomegalovirus. This virus is usually transmitted by saliva and, less frequently, by blood or through sex.

When someone is infected by this virus, they often have few symptoms or none at all. However, in some cases the virus can make a person seriously ill. This happens when the defense system is weak, for example. Some of the virus remains in the body throughout the person’s life so it can cause illness later, too.

The lungs are on the left and right side of the ribcage. They are also connected to the nose and mouth via the bronchial tubes and windpipe (trachea). If the lungs are inflamed, you will have breathing problems, a cough, or a high temperature, for example.
