<\/span><\/h2>\nRoseola is a disease caused by the human herpes virus type 6B (HHV-6B) and possibly type 7 (HHV-7). These herpes viruses have only been identified in recent years, and we are still learning about the full range of diseases caused by them.<\/p>\n
Roseola is characterized by high fever<\/span> Lasts 3-5 days, runny nose, irritability, and tiredness. As the fever decreases eruption<\/span> (exanthema<\/span>) can appear on the face and body.<\/p>\nRoseola is also known by the names roseola infantum and exanthem subitum.<\/p>\n\n<\/span>Roseola<\/span><\/h5>\n<\/section>\n\n\n

<\/span>Who gets roseola?<\/span><\/h2>\nRoseola is most often seen in children between 6 months and three years of age. Most children (86%) will have had roseola by the age of 1 year. Roseola is rarely seen in adults, since infection<\/span> during childhood it will probably confer lifelong immunity to the disease. Repeated attacks are known to occur, but are not common.<\/p>\n\n

<\/span>How is roseola spread?<\/span><\/h2>\nRoseola is transmitted from person to person through the saliva of asymptomatic<\/span> members of the family. the incubation<\/span> The period for roseola is approximately 9-10 days after exposure.<\/p>\n<\/span>What are the signs and symptoms of roseola?<\/span><\/h2>\nIn many cases of roseola, the child looks good with little or no signs or symptoms. Typical cases are characterized by the following:<\/p>\n
\n- High fever (often up to 40 C) for 3 to 5 days.<\/li>\n
- Symptoms of the upper respiratory tract, such as a sore throat, cough, runny nose, or congestion.<\/li>\n
- Irritability and tiredness.<\/li>\n
- The rash appears around days 3-5, as the fever subsides\n
\n- Usually small pinkish pink or red dots (2\u20135 mm in diameter) that whiten<\/span> (turns white) when touched<\/li>\n
- Some spots may be surrounded by a lighter halo of pale skin<\/li>\n
- It mainly affects the trunk and rarely extends to involve the neck, face, arms, and legs.<\/li>\n
- Similar spots appear on the soft palate and uvula (Nagayama spots)<\/li>\n
- Does not itch, does not hurt and does not blister<\/li>\n
- It can disappear in a few hours or persist for two days.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
In some cases, a child may be infected with the virus and never develop the rash. Less often, the rash may appear without a previous fever. In most cases, particularly if the fever is low, the child is fine. In about 5 to 15% of young children, high fevers can trigger febrile<\/span> seizures<\/p>\n<\/span>How is roseola diagnosed?<\/span><\/h2>\nBecause roseola is usually mild and self-limiting, diagnosis is generally based solely on characteristic history and physical examination.<\/p>\n
Some labs can confirm HHV-6 infection by serology<\/span> or Polymerase chain reaction<\/span> (PCR<\/span>)<\/p>\n\n

<\/span>What is the treatment for roseola?<\/span><\/h2>\nThere is no specific treatment for roseola. The disease is usually mild and self-limiting. Rest, fluid intake, and acetaminophen for fever are all that is generally required. No treatment for the rash is necessary as it does not itch or hurt and spontaneously fade away.<\/p>\n
<\/span>What are the complications of roseola?<\/span><\/h2>\nComplications are rare with roseola in most children. The most common complication is febrile seizures \/ convulsions that can occur in 5 to 15% of children. These are triggered by high roseola fevers and can be alarming when they are first seen. Signs of a febrile seizure include:<\/p>\n
\n- Loss of consciousness<\/li>\n
- Sudden or jerky movements in the arms, legs, or face for 2 to 3 minutes.<\/li>\n
- Wet or dirty pants on an unconscious child, trained to go to the bathroom<\/li>\n
- Irritability<\/li>\n<\/ul>\n
These seizures are brief and not dangerous. However, you should have a doctor examine your child if one occurs.<\/p>\n
