Fifth disease is a common infection affecting the skin, upper airway, and joints. It is caused by a virus known as Human Parvovirus B19 and tends to spread during the late winter to early spring. It usually appears as a very red rash on a child’s cheeks, giving a “slapped cheek” look. Fifth disease is usually very mild. It is usually more severe in adults. Most people who had fifth disease as a child will not get it again.
Pregnant women who are not immune usually do not have serious complications after being exposed to others with fifth disease. In most cases, these babies will not have any problems. However, sometimes a baby will develop severe anemia. If you are pregnant and develop a rash or have sore joints and have been exposed to someone with fifth disease (or to anyone with an unusual rash), call your healthcare professional.
