Roseola, or sixth disease, is a highly contagious viral infection that affects children. It usually begins with a fever that lasts for two to four days and is followed by the appearance of a rash on the trunk and face. Although it can be alarming for parents to see their child’s temperature spike so high, roseola typically resolves itself within about 10 days without any long-term effects.
Here, we’ll discuss what causes roseola, how it’s treated, and when you should seek medical attention for your child if they develop it. With the right knowledge and precautions in place, your family can stay safe and healthy.
History and Definition
Roseola, also known as exanthem subitum or sixth disease, has been recognized for over a century. In 1910, a pediatrician named Thomas Morgan Rotch described a new disease he had observed in his patients, which he named “rose rash of infants”. However, it wasn’t until the 1960s that the virus responsible for the disease was identified.
Roseola is caused by two strains of the herpesvirus family, human herpesvirus 6 (HHV-6) and less commonly human herpesvirus 7 (HHV-7). HHV-6 was first discovered in 1986, while HHV-7 was identified in 1990. Both viruses are ubiquitous and can be found in most people’s saliva, with primary infection usually occurring in early childhood.
Roseola is a common viral illness that primarily affects infants and young children between the ages of six months and two years. The disease is typically characterized by a sudden onset of high fever, which can last for up to a week, and is often accompanied by other symptoms such as irritability, runny nose, cough, and swollen lymph nodes. Once the fever breaks, a distinctive rash appears on the child’s trunk, which spreads to the arms, neck, and face. The rash typically lasts for one to two days before fading away.
While roseola is generally a benign illness, it can be more serious in children with weakened immune systems or in rare cases when complications such as seizures or encephalitis occur. It is important to seek medical attention if a child with roseola experiences seizures, difficulty breathing, or other concerning symptoms.
Symptoms
The symptoms of roseola typically appear after a short incubation period of around five to 15 days after exposure to the virus.
The initial symptoms of roseola are usually non-specific and can include:
- High fever (often over 103°F or 39.4°C), which can last for up to a week
- Irritability and fussiness
- Runny nose, cough, and sore throat
- Swollen lymph nodes in the neck
Once the fever subsides, a distinctive rash appears on the child’s body, which can spread to the arms, neck, and face. The rash is typically pinkish-red and consists of small, flat, and raised bumps that may be slightly raised or have a white center. The rash usually lasts for one to two days before fading away.
In addition to fever and rash, some children with roseola may experience other symptoms, such as:
- Loss of appetite
- Mild diarrhea
- Mild earache
- Mild sore throat
It’s important to note that some children with roseola may experience seizures, particularly during the fever phase. These seizures are typically brief and do not cause long-term harm, but it’s important to seek medical attention if a child experiences seizures or other concerning symptoms.
Causes
Roseola is caused by two strains of the herpesvirus family: human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7). Both viruses are very common and can be found in most people’s saliva, with primary infection usually occurring in early childhood.
Transmission of HHV-6 and HHV-7 usually occurs through close contact with an infected person, particularly through saliva or respiratory secretions. The viruses can also be transmitted through blood transfusions or organ transplants, but this is rare.
Once a person is infected with HHV-6 or HHV-7, the virus can remain dormant in the body for years without causing any symptoms. However, in some cases, the virus can reactivate and cause symptoms such as roseola.
It’s important to note that while roseola is most common in infants and young children between six months and two years of age, adults can also contract the virus and develop symptoms of roseola. However, the illness tends to be milder in adults.
Diagnosis
The diagnosis of roseola is usually based on the characteristic symptoms of the illness. A healthcare provider will typically begin by taking a medical history and conducting a physical examination, which may include checking for the presence of a fever, swollen lymph nodes, and a rash.
In some cases, laboratory tests may be used to confirm the diagnosis of roseola or to rule out other possible causes of the child’s symptoms. These tests may include:
- Blood tests to check for the presence of antibodies to HHV-6 or HHV-7
- Viral cultures to detect the presence of the virus in saliva or other body fluids
- Polymerase chain reaction (PCR) tests to detect the virus’s genetic material in blood or other samples
While laboratory tests can help confirm the diagnosis of roseola, they are not always necessary, as the illness is usually diagnosed based on characteristic symptoms.
It’s important to note that other illnesses, such as measles, rubella, and scarlet fever, can cause similar symptoms to roseola. Therefore, it’s important to consult a healthcare provider if a child develops a fever and rash or if there are concerns about their symptoms.
Treatment
There is no specific treatment for roseola, as the illness is caused by a viral infection that typically resolves on its own within a week or two. In most cases, treatment for roseola is focused on relieving symptoms and keeping the child comfortable.
Some common strategies for managing symptoms of roseola include:
- Administering acetaminophen or ibuprofen to reduce fever and relieve discomfort
- Offering plenty of fluids to prevent dehydration
- Encouraging rest and relaxation
- Using cool compresses or baths to soothe the skin and relieve itching
- Keeping the child’s fingernails short to prevent scratching and infection
- Monitoring for signs of complications, such as seizures
In rare cases where a child experiences seizures, medical treatment may be necessary. However, most children with roseola recover fully without the need for medical intervention.
It’s important to note that while there is no specific treatment for roseola, it’s still important to seek medical attention if a child develops concerning symptoms or if symptoms worsen over time. Additionally, it’s important to take steps to prevent the spread of the virus, such as practicing good hygiene and avoiding close contact with others while the child is contagious.
Risk Factors
While the illness is generally mild and self-limiting, certain risk factors can increase the likelihood of a child developing roseola or experiencing complications.
Some common risk factors for roseola include:
- Age: Roseola is most common in infants and young children between six months and two years of age, with the peak incidence occurring between nine and 12 months.
- Lack of immunity: Children who have not been exposed to the viruses that cause roseola may be at increased risk of developing the illness.
- Close contact with infected individuals: Roseola is spread through close contact with an infected person, particularly through saliva or respiratory secretions.
- Weakened immune system: Children who have weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, may be at increased risk of developing complications from roseola.
- Preexisting medical conditions: Children with preexisting medical conditions, such as asthma or eczema, may be at increased risk of experiencing complications from roseola.
While these risk factors can increase the likelihood of a child developing roseola or experiencing complications, it’s important to remember that the illness is generally mild and self-limiting. Most children with roseola recover fully without any long-term complications. However, it’s still important to take precautions to prevent the spread of the virus and to seek medical attention if symptoms worsen or new symptoms develop.
Complications
In rare cases, the illness can lead to complications, particularly in children with weakened immune systems. Some potential complications of roseola include:
- Febrile seizures: High fever associated with roseola can sometimes lead to febrile seizures, which are seizures that occur in young children when their body temperature rises quickly.
- Encephalitis: In rare cases, the viruses that cause roseola can cause inflammation of the brain, leading to encephalitis.
- Meningitis: The viruses that cause roseola can also cause inflammation of the membranes that surround the brain and spinal cord, leading to meningitis.
- Pneumonia: Roseola can sometimes lead to pneumonia, particularly in children with weakened immune systems.
- Thrombocytopenia: Rarely, roseola can cause a decrease in the number of platelets in the blood, which can lead to abnormal bleeding or bruising.
While these complications are rare, it’s still important to seek medical attention if a child with roseola experiences concerning symptoms or if symptoms worsen over time. Parents and caregivers should monitor the child closely and seek medical attention if necessary.
When to See a Doctor
Parents and caregivers should consider seeking medical attention if a child with roseola experiences any of the following symptoms:
- High fever: While a high fever is a common symptom of roseola, it’s important to seek medical attention if the child’s fever is particularly high or if it persists for an extended period of time.
- Seizures: Febrile seizures can sometimes occur in young children with roseola, particularly if their body temperature rises quickly. If a child experiences a seizure, it’s important to seek medical attention immediately.
- Rash or other skin changes: While a rash is a common symptom of roseola, it’s important to seek medical attention if the rash is particularly severe or if it spreads to other areas of the body.
- Difficulty breathing: Roseola can sometimes lead to complications such as pneumonia, which can cause difficulty breathing. If a child with roseola is having trouble breathing, it’s important to seek medical attention immediately.
- Signs of dehydration: Children with roseola may be at increased risk of dehydration due to fever and decreased fluid intake. Signs of dehydration include dry mouth, decreased urine output, and lethargy.
- Compromised immune system: Children with weakened immune systems may be at increased risk of developing complications from roseola. If a child has a compromised immune system, it’s important to seek medical attention if any symptoms of roseola develop.
Overall, while most cases of roseola are mild and self-limiting, it’s still important to seek medical attention if a child experiences concerning symptoms or if symptoms worsen over time. Parents and caregivers should monitor the child closely and seek medical attention if necessary.
