Cytomegalovirus

Cytomegalovirus (CMV) is a common virus that can infect almost anyone. Once infected, your body retains the virus for life. Most people don't know they have CMV because it rarely causes problems in healthy people.

 CMV spreads from person to person through body fluids, such as blood, saliva, urine, semen and breast milk. There's no cure for the virus. However, medications can help treat newborns and people with weak immune systems.

Babies

Most babies with congenital CMV appear healthy at birth. A few babies with congenital CMV who appear healthy at birth can develop signs over time — sometimes not for months or years after birth. The most common of these late-occurring signs are hearing loss and developmental delay. A small number of babies may also develop vision problems.

Kawasaki Disease

Kawasaki Disease Kawasaki disease is an illness that almost always affects kids, most of them under the age of 5. It’s one of the leading causes of heart disease in children. Causes When a child has Kawasaki disease, the blood vessels throughout his body become inflamed. This can damage the coronary arteries, the vessels that carry  blood  to his heart. But Kawasaki disease doesn’t affect just the heart. It can also cause problems with lymph nodes, skin, and lining of the  mouth , nose and throat. Scientists haven’t found an exact cause for Kawasaki disease . But they think it’s probably linked to a combination of genetics, exposure to viruses and bacteria, and other environment factors, such as chemicals and irritants.
