Roseola infantum

A sudden infection of small children, with fever, swelling of the lymph glands and a rash. It is caused by herpesvirus 6.

An infectious, probably viral, disease common in young children, especially those under two years old, involving an abruptly arriving high fever, as high as 105°F, which lasts for four to five days and then drops back to normal, at which time a pink rash spreads over the body, especially the trunk, neck, and thighs, generally lasting from a few hours up to two days. Accompanying symptoms may be sore throat, swollen lymph nodes in the neck, and sometimes convulsions or seizures. In the absence of a specific therapy, the main treatment is generally to bring the body temperature down, as by giving a sponge bath with lukewarm water or giving acetaminophen (not aspirin, because of its link to Reye’s syndrome).

Benign illness of infants and young children. Characterized by abrupt, high fever; mild sore throat; and, a few days later, a faint, macular, pinkish rash that lasts for a few hours to a few days. Treatment involves fever- reducing agents (e.g., acetaminophen), and, if convulsions occur in association with high fever, anticonvulsants.

A benign infectious disease, usually caused by human herpesvirus 6 (HHV-6), that typically affects infants and young children between the ages of 6 months and 3 years. Roseola infantum is characterized by a high fever and a rash, which breaks out as the fever lessens. There are no other symptoms, and the infant or child is generally alert and active during the illness. The high temperature begins abruptly and may rise to as high as 105°F. In some cases, there may be seizures as the temperature increases. The fever rapidly declines by the third or fourth day of illness, and a rash then appears, most commonly on the chest and abdomen, but also sometimes on the face, arms, and legs. The rash is short-lived and may disappear after a few hours to a few days. Body temperature, at this point, returns to normal.

A transient exanthem of toddlers. Mild malaise is followed by a rubella-like rash. It is caused by herpes virus 6.

Roseola infantum is a widespread infectious illness, mainly affecting children between six months and two years old. Caused by a herpes virus, the disease begins suddenly with signs of irritability and fever. After about four or five days, the child’s temperature returns to normal, roughly coinciding with the appearance of a rash on the torso, which may also extend to the neck, face, and limbs. The rash typically fades away within two days.

Additional symptoms might encompass a sore throat and swollen lymph nodes in the neck. While seizures can happen during the feverish phase, the condition generally doesn’t have severe consequences.
